Comments Proposed change Observations of the secretariat

1 FR01 ge FRNC supports the proposal with the following comments :

Noted

2 GB01 ge The British National Committee supports this document without comment.

Noted

3 CH01 ge The CH NC regrets to reject 61/5991/DC due to the following reason(s).

See 8

4 AU01 ge Australia has already made changes to this standard to cover the risk of electric shock as described in this DC however the scope was not expanded to include swimming pools. We understand the intent is to expand the scope of the standard to pools. Australia is also currently looking into this, but more work is required to ensure it is mature enough to share. We suggest waiting until the Australian proposal is submitted to discuss further.

See 8

5 CH02 Background

ge Requirement for installations can have some differences to the requirements for products. Within the product the rules of IEC 60335 apply, the installations rules shall be applied only until the socked-outlet. The safety of “transportable whirlpool spas” is guaranteed by the special requirements adapted to the product in question, which are described in IEC 60335-2-60. The installation standards cannot be compared with a product standard. Only the standard of a product can take into account its specific details and safety issues.

(e.g. Table 1)

6 DK01 ge The “background” provided for this proposal is not fully understood. In particular it is indicated that there has been “…failure of cl. II insulation where metal parts are not connected to earth…the water was in contact with mains voltage… allowed by the standard”.However, the fact that water had reached live parts due to a failure of “cl. II insulation” suggest that a single-layer the reinforced insulation has been used. Such construction is however prohibited by the second paragraph of cl. 22.33. Therefore, it would appear that the appliances in question are not compliant with the standard.If the “cl. II insulation” consist of separate basic- and supplementary insulation or of reinforced insulation of minimum 3 separate layers as required in cl. 22.33 then water entry to live parts resulting from a failure of the “cl II insulation” appear to be preventedSimilar requirements are also provided in cl. 22.106 of 60335-2-60.Additionally, the DK NC questions the relation to IEC 60364-7-702 in connection with whirlpool spa’s.IEC 60364-7-702 cover installation requirement for swimming pools and ponds. A swimming pool is defined as a “water basin designed for swimming, diving etc”A whirlpool spa is not designed for swimming or diving and would normally not be sufficiently large for this purpose. Therefor the reference to IEC 60364-7-702 should not be made and instead IEC 60364-7-701 would be sufficient to

See 8





(e.g. Table 1)

Type of comment


cover requirements for both whirlpool baths and spa’s(following their definitions the difference between these appliances is mainly whether or not they are being drained after each use).

7 DK02 2 1 te Adding the word “spas” as proposed does not make sense. The third paragraph specify that the standard also cover appliances for circulating air or water in conventional baths. Per definition a “spa” already include provisions for circulating air or water.A “spa” is already included in the scope and should not be added in this paragraph

Delete line 2 of the proposal See 8

8 NZ01 2 1 te The term spa has no meaning with respect IEC 60364-7-702. We presume the intention is to expand the scope of the standard to cover swimming pools that are defined in IEC 60364-7-702 as “water basin designed for purposes such as swimming, diving, etc. and not for personal cleaning activity” whereas whirlpool spas are not designed swimming or diving activities.

More details of examples of what is intended if swimming pools are added to the scope.

Regarding the question of whether whirlpool spas are covered by 60364-7-701 or 60364-7-702, during the meeting it was decided to setup an ahG to work during the course of the 2020 web meeting series to prepare the questions that would be presented from IEC TC61 to IEC TC 64 and for an overall analysis of the proposals concerning 2-60 covered by the document under discussion (61/5991/DC ) and those being prepared by AU NC (see also comment AU01 #4). The Convenor of the ahG was Adam Murdoch (AUNC). The following





(e.g. Table 1)

Type of comment


experts volunteered to participate on the ahG: Thijs van Zanten (NLNC), Derek Johns (NZNC), Thabo Mabena (ZANC), Danilo Kraner (SINC) and Severo Nicoli (CHNC).Update 23 November 2020: The report from the ahG was provided during the TC 61 web meeting held 23 November 2020.The ahG prepared the request to IEC TC 64, including that a formal decision of the TC is requested, considering the opinion of NCs in the TC, and that the decision shall be clarified in an amendment to the applicable standard (7-701 or 7-702) to eliminate the uncertainties on whether 60364-7-701 or 60364-7-702 shall be applied to whirlpool SPAs.Based on the answer to be received from IEC TC 64, TC 61 will determine whether to form a WG to review the scope of 2-60 and application of the standard for different appliances and develop modifications to be covered in a new DC for 60335-2-60. This will include addressing the clarification from IEC TC 64, updates

needed for the proposal from NL NC and the additional proposals being developed by AU NC. As a result of the above actions, it was agreed to postpone the Stability Date for 60335-2-60 to 2022.

9 FR02 3.5.1 Note 1 te Modification: Delete the word ‘Transportable’ in Note 1 to entry.The note avoids confusion between transportable and portable.

Keep note 1 to entry See 8

10 CH03 9-16 3.5.1 ed “Transportable whirlpool spas” are a defined kind of product. Do not make confusion with the definition: “portable appliance”. This note 1 just clarify the fact that “transportable whirlpool spas” are not “portable appliances“;for example because they are heavier than 18 kg. To delete the word “transportable” do not make sense.

Don't change clause 3.5.1 See 8

11 US01 13, 14 te The Note in 3.5.1 for Portable Appliance should not be revised. The definition as currently published suffices.

The Note clarifies that a Transportable Whirlpool Spa is not considered Portable. Removing the word “transportable” may lead to confusion, if a transportable spa then is considered portable. Also, to avoid classifying a whirlpool spa as a portable appliance, the term Portable in Part 1 already applies and is sufficient

Last, the rationale indicates that “…when full with water is more than 18kg..”. There is no requirement in Part

1 or part 2 to measure the weight with or without water.

However, if the proposed change does not occur, then this carries thru to other parts of the submitters proposal as well, which may need to be reconsidered.

12 CH04 17-22 5.101 te There is no reason to reduce the severity of the requirements only because the installations rules say that. This art of product need these severity of requirements.

Don't change clause 5.101 See 8

13 NL01 19 5.101 te As a consequence of the deletion of 5.101 some requirements for portable appliances in this standard and in part 1 are not applied anymore to transportable spas while some of these however are relevant for portable spas and required by the existing part 2-60.With regard to 7.15:The easy visibility of markings for portable appliances shall also apply to transportable whirlpool spas (as is the case in the existing part 2-60)13.2:Transportable whirlpool spas are plug connected appliances just like portable appliances. Therefore there is an increased risk that these appliances are not connected to an earthed socket outlet. As a result the leakage current limits for class I portable appliances should apply for class I transportable whirlpool spas (as is the case in the existing part 2-60)16.2:Transportable whirlpool spas are plug connected appliances just like portable

The following additions are necessary:

7.15 Modification:For portable appliances and transportable whirlpool spas, it shall be possible to remove or open this cover without the aid of a tool.

13.2 Modification:(9th paragraph - 4th dashed item).

- for portable class I appliances and class I transportable whirlpool spas 0,75 mA

16.2 Modification:(4th paragraph -3rd dashed item).

- for portable class I appliances and class I transportable whirlpool spas 0,75 mA

22.104 Modification:In the first paragraph add the words ‘and transportable whirlpool spas’ after the word appliances.

appliances. Therefore there is an increased risk that these appliances are not connected to an earthed socket outlet. As a result the leakage current limits for class I portable appliances do apply fro class I transportable whirlpool spas (as is the case in the existing part 2-60)

22.104:These requirements are also applicable to transportable whirlpool spas (as is the case in the existing part 2-60). Transportable whirlpool spas may be moved from time to time and they do not have a fixed location, therefore there is an increased risk of putting the appliance on a non hardened surface (e.g. lawn) where small objects may penetrate the underside.25.19:These requirements are also applicable to transportable whirlpool spas (as is the case in the existing part 2-60).

25.19 Modification:For type X attachment, glands shall not be used as cord anchorages in portableappliances and transportable whirlpool spas.

14 NZ02 19 5.101 te We do not agree with the deletion of this subclause It is important for the correct application of Part 1 particularly for the leakage current limits in Clause 13.2, 16.2 and other clauses such as 25.9, 25.21 etc. Its deletion will lead to a reduction in the level of safety for transportable whirlpool spas.

Reject the proposal. See 8

17 US03 28, 36 6.1 te 6.1 is about the classification. The voltage limitation should be included in Clause 22 instead. This should be covered in the 22.33 Addition, similar to the requirements in 22.26 of -2-8 or 22.36 of -2-52.

Delete lines 28 and 36 and update 22.33 if needed

Parts in contact with the water shall be class III construction having a working voltage not exceeding 12 V.

See 8

18 CH05 31-37 6.1 te By changing the second paragraph, all the requirements for “transportable whirlpool spas” are overturning and they do not make sense anymore. The safety of this kind of product is no longer given.

Don't change the second paragraph:”Transportable whirlpool spas having metal parts in contact with water shall be class I or class III.”

See 8

19 DK03 42-43 6.2 te It does not make sense to require a certain IP rating for the tub itself of whirlpool bath’s and spa’s. IEC 60529 which defines the IP classes and associated requirements is a standard aimed at “enclosures” and degree of protection provided by enclosures. As the tub is fully open at the top it cannot be considered as an enclosure in this context. Rather it is a water basin.

As defined in 60529 the tub can be considered as an enclosure for the parts of the appliance located beneath the tub but it is obviously understood and follows from the requirements throughout the standard that the tub is sufficiently watertight to prevent water from penetrating into area containing live parts and that electrical part of the appliance that are located in the tub are equally water tight.

Delete the last sentence of the proposed text in both line 42 and 43 starting with “the tub/basin…”

See 8





(e.g. Table 1)

Type of comment


In this context an IPX7/X8 requirements for the tub is meaningless and will also present considerable practical problems testing appropriately.

20 DK04 42-43 6.2 te The proposed modification sets different requirements for whirlpool baths (IPX4) and whirlpool spa’s (IPX5). The argument is that whirlpool baths could be subject to cleaning with water jets.It is not understood why this should be the case. From a general perspective whirlpool-baths and -spa’s are used and cleaned in the same way and thus same requirements should apply.There may be an underlying assumption that whirlpool spa’s are only used outdoors but that is not always the case. Whirlpool spa’s may also be located and used indoors.If this is the intent behind the differentiation, then a separate requirement, specific for appliances used outdoors should be made.

Modify the proposed text to specify same requirements for IP classification of whirlpool baths and spa’sIf necessary, add additional requirements for appliances for use outdoors

See 8

21 NO01 42 6.2 te We do not understand the background for the IPX7 and IPX8 immersion-tests. What is the purpose? How to perform these tests?In addition, as IPX8 is not described in part 1, clarification of test criteria should be given.

A description of these tests are necessary.

See 8

22 DK05 44-45 6.2 te The requirements for “other appliances” in this context may be misunderstood. For clarity and to prevent misunderstanding some rephrasing is proposed.The strikethrough is following DK02

Modify the text in line 44-45 so that it reads:“Submersible appliances for use with a conventional bath or spa shall be at least IPX8. Other appliances shall be at least IPX5”

See 8

23 NZ03 42-45 6.2 te We do not understand why the Reject the proposal relating to IPX8. See 8





(e.g. Table 1)

Type of comment


“tub/basin” has to be IPX7 or IPX8. It is just the part that contains the water, it is not immersed in the water.Also why should appliances used in a conventional bath be IPX8 – we are not aware of conventional baths with a depth of 1 m or more.See swimming pool examples in the Annex.

24 NO02 46-47 6.2 ed To state “at least IPX0” (lowest classification) is not necessary.

Change the text to:“Parts of appliances intended for mounting within the dwelling but outside the zones 0, 1 and 2 as specified in IEC 60364-7-701 and IEC 60364-7-702 shall be at least IPX0 do not need any IP-classification”.

See 8

25 NL02 51 7.12 te The requirement in 7.12 of existing part 2-60 that for portable appliances no part of the appliance is to be located above the bath during use, should also be applicable to whirlpool spas.

Add the following to the proposal:

7.12 Modification:In the second paragraph of the addition add the words ‘or spa’ after the word ‘bath’.

See 8

26 NL03 60 13.1 te Considering the severity of electric shock at appliances under part 2-60, protective impedance and radio interference filters (such as Y-capacitors) shall not be disconnected / removed for the tests of 13.2. The leakage current shall be limited to safe values no matter if the leakage current is due to protective impedances, filter capacitors or leakage through solid insulation. After all it is the total leakage current that, when passing through the human body, causes electric shock. Therefore the total leakage current shall be measured and be below the limits given in 13.2.


13.1 Modification:Protective impedance and radio interference filters are disconnected only before carrying out the tests of 13.3.

27 NL04 60 13.2 te Leakage current from surfaces / parts that are not accessible by the user (clause 8) but that are accessible by the water (in which the user is immersed) must also be measured. This is however lacking in the current part 2-60.


13.2 In part 1 delete the 3rd paragraph and replace the 2nd paragraph by the following:

The leakage current is measured between any pole of the supply and– accessible metal parts intended to be connected to protective earth, for class l appliances;– metal foil having an area not exceeding 20 cm x 10 cm which is in contact with accessible surfaces of insulating materials and metal parts not intended to be connected to protective earth, for class II appliances, class ll constructions and class III appliances. The metal foil has the largest area possible on the surface under test without exceeding the dimensions specified. If its area is smaller than the surface under test, it is moved to test all parts of the surface. The heat dissipation of the appliance is not to be affected by the metal foil;– metal foil which is in contact with surfaces of insulating materials, and unearthed metal parts, that are in contact with the water of the bath or spa in normal use, for class II appliances, class ll constructions and class III appliances. The metal foil shall have such an area that it covers the whole surface of the part in contact with the water. The heat dissipation of the appliance is not to be affected by the metal foil.

See 8

28 NL05 60 16.1 te Considering the severity of electric shock at appliances under part 2-60,

protective impedance shall not be disconnected / removed for the tests of 16.2. The leakage current shall be limited to safe values no matter if the leakage current is due to protective impedances, filter capacitors or leakage through solid insulation. After all it is the total leakage current that, when passing through the human body, causes electric shock. Therefore the total leakage current shall be measured and be below the limits given in 13.2.

16.1 Modification:Protective impedance is disconnected from live parts only before carrying out the tests of 16.3.

29 NL06 60 16.2 te Leakage current from surfaces / parts that are not accessible by the user (clause 8) but that are accessible by the water (in which the user is immersed) shall also be measured. This is however lacking in the current part 2-60.


16.2 Modification:Add the following as a third dashed item to the text of the first paragraph in part 1:– metal foil which is in contact with surfaces of insulating materials, and unearthed metal parts, that are in contact with the water of the bath or spa in normal use, for class II appliances, class ll constructions and class III appliances.

See 8

See 8

31 CA01 64 22.33 - te The proposal suggests to delete the second paragraph of the original addition to 22.33. The CANC does not believe that is correct as these requirements are still valid and necessary to clarify what types of circuits are allowed in accessible controls.

Replace line 64 of the proposal with the following:“Delete the first paragraph and note of the addition”.

controls accessible to the user in the whirlpool bath or whirlpool spa shall only be supplied at safety extra-low voltage not exceeding 12 V.”

33 NL08 64 22.33 te An error has occurred in 22.33 to delete the entire addition. The NLNC had the intent to only delete the 1st paragraph including note 101.

Replace line 64 by the following:

Delete the 1st paragraph and note 101 of the addition.

See 8

34 NL09 63-64 22.33 te The existing requirement in the 2nd paragraph of the addition in part 2-60 should be extended for electric parts that are mounted in the walls of the tub / basin of whirlpools baths or spas (such as lamps) since any energized part in the tub/basin (zone 0) shall be of class III construction with a voltage not exceeding 12 V.


22.33 Replace the second paragraph of the addition by the following:

Parts mounted in the basin or in walls of the basin, such as lamps or luminaires, and parts accessible to the user in the whirlpool bath or whirlpool spa such as switches and controls, shall only be supplied at safety extra-low voltage not exceeding 12 V.

See 8

35 DK06 64 22.33 te The second paragraph of the addition specifying that“parts such as switches and controls accessible to the user…. shall only be supplied at SELV not exceeding 12V” is still relevant and should not be deleted

would for example prevent control switches being accessible to the user while they are using the appliances. It is not in conflict with 8.1.4

38 US04 61-66 22.33 te Deleting the Addition to Clause 22.33 in IEC 60335-2-60 would have unintended consequences for the pool and spa industry. In addition to whirlpool baths and whirlpool spas, this standard has been used for related products that provide health and sanitization benefits such as electrolytic chlorine generation systems which use electrolysis to produce chlorine from the dissolved salt in the pool water and sanitization automation systems which rely on probes immersed in the pool or spa water to measure water chemistry and make appropriate adjustments to maintain water quality.

These technologies have been used successfully for 30+ years. In the absence of any other Part 2 standard, the “addition” in Clause 22.33 in 60335-2-60 has provided a -2 means for recognizing these technologies. The parts of the product that are in contact with water are low voltage as specified in Clause 22.33 of 60335-2-60. These products incorporate appropriate methods such as double insulation, safety isolation transformer, etc. for isolating the mains from the water contact points

If the existing “addition” were to be removed, it could potentially eliminate these important technologies that provide beneficial health and

DECISION: The ahG formed during the meeting developed a letter that will be sent to IEC TC 64 to request that a formal decision of TC 64 is requested, considering the opinion of NCs in the TC, and that the decision shall be clarified in an amendment to the applicable standard (60364-7-701 or 60364-7-702) to eliminate the uncertainties on whether 60364-7-701 or 60364-7-702 shall be applied to whirlpool SPAs.

Based on the answer to be received from IEC TC 64, TC 61 will determine whether to form a WG to review the scope of 60335-2-60 and application of the standard for different appliances and develop modifications to be covered in a new DC for 60335-2-60. This will include addressing the clarification from IEC TC 64, updates needed for the proposal from NL NC and the additional proposals being developed by AU NC.

As a result of these actions, it was agreed to postpone the Stability Date for 60335-2-60 to 2022.

4 DK01 ge The DK NC does not agree in this proposal and at least in the way it is phrased we do not believe it is sufficiently mature to provide the necessary level of safety of appliances using this construction.

We also do not quite understand how the proposed constructions can practically operate.

See 3 and 5.A practical operation of the proposed construction is outlined in the rationale of the proposal.

5 NZ01 ge We are against this proposal since safety relies on the water conductivity being below a specific value. Also it does not meet the requirement for Class I appliances in 7.3 of IEC 61140 which is a basic safety publication.There are many areas of the world where the water conductivity may be above the specified value and hence a safety issue will exist.As a consequence, this proposal should not be included in the International standard. It is a proposal for national use in those countries that have water supplies that can meet the specified conductivity requirements.The same issue applies in Part 2-35 for instantaneous water heaters incorporating bare element water heaters. Requirements for these types of instantaneous water heaters is also a national issue and should be removed from the international standard.

Delete the proposal. Not accepted. Concept 1

(61(2020Web/CHNC)107) relies on the “Protection by limitation of steady-state touch current and charge” (IEC 61140 cl. 6.9), which provides the construction's safety regardless of the liquid conductivity by supplying the electrodes with a protective impedance device.

Concept 1 (61(2020Web/CHNC)107) also includes a class I construction according to IEC 61140 cl. 7.3, where all conductive parts are separated from hazardous-live-parts and the mains, by at

8 DK02 8 3.1XX te The definition does not provide sufficient clarity. It is assumed that the intent is to define a unit that heats the water via the electrical conductivity of the water itself as described in the rationale. However apart from the word “direct” this definition may just as well cover a heating unit using an ordinary resistive heating element.The word “direct” is not sufficient to clearly describe the intent type of heating without the support of the rationale and so it may cause misunderstandings.

Modify the definition to provide a clearly understandable description of the relevant heating principle.

15 DK07 49 19.X te The term “protective electronic circuit” is already defined in IEC 60335-1.According to the “rationale” and introduction of this proposal, a “protective electronic circuit” is a circuit that monitors “touch current” and limits this to be in accordance with cl. 8.1.4 or 13.2This is quite different from the existing definition of the same terms and therefor this term cannot be used as in the context of this proposal.

Rephrase the proposal to refrain from using the term “protective electronic circuit” in the context as proposed.

17 DK09 29-31 22.33 te Considering that only the electrodes of a direct heating unit are connected through devices that control the associated leakage current, it will be necessary to specifically limit the allowance for direct contact of water with live parts only to the electrodes of a direct heating unit and not for any other part of such appliance.

Additionally, the specification that the inlet and outlets being connected to the earthing terminal seems to contradict with allowance in cl. 6.2 for using cl. II constructions

28 AU03 22.X.5.3 te This clause should require an Isolation transformer

Delete reference to “transformer or a switch mode power supply unit” and refer to isolation transformer complying to IEC 61558-2-4:2009

Accepted to delete reference to “switch mode power supply unit.”

As stated in the IEC 61558 series, the definition of a transformer has an internal operating frequency below 500Hz. Transformers with an internal operating frequency above 500Hz are classified as switch mode power supplies.

The IEC 60335 series does not differentiate these cases and allows transformers to be operated with an internal operating frequency greater than 500Hz.

It was agreed 22.X.1 defines the required isolation. Therefore, the required transformer, separating (basic insulation) or isolating (double or reinforced insulation), should depend on that requirement.

In alignment with 60335-2-115 it was agreed to add the following:Isolating transformer additions:

Add IEC 61558-2-4 in normative references of Clause 2.

Also, add in 24.1.2 “The

3 AU01 We vote against this proposal. In all states and territories in Australia, it is illegal to sell, possess or use e-cigarettes that contain nicotine. The 60335 series of standards has always looked to keep the user of the appliance safe. The function of these appliances poses a known and serious risk to the health of users that can only be overcome by not using them. If a standard is really required it should be standardised under a different committee, perhaps relating to medical or therapeutic goods .

The general consensus among regulators has been that the most stringent requirements shall be applied to such devices. This draft does not address internal short-circuit due to mechanical stresses, wide range of operating temperatures (e.g., very cold/hot), mechanical abuses. Also, it’s heavily relied upon the data provided by the manufacturers that may apply different, non-standardized test methods, not adhered to ISO lab quality programs.

34 US06 132 3.1.9 te How do we ensure gauge R&R if we permit a wide range of operating parameters? Test results will vary. Operating the devices under no-load state does not represent the actual use conditions. It’s not appropriate to define general test conditions in Clause 3, terms and definitions, instead, it should be part of Clause 5, general conditions for the tests.

The proposed puffing cycle is based on the big data extracted from a data set of 403,000 recorded sessions out of 750 devices used by consumers in the market. The general misconception with puffing regime used in ISO 3308, i.e., 35/55 mL once every 60s/30s is that, this smoking regime is intended to measure the cigarette content and emissions, however, the purpose of this standard is to address electrical safety (not chemical toxicity), in this sense, the worst-case smoking regime representing actual consumer behaviours shall be used, e.g., very rare smoker would stop smoking for an interval of 30s or 60s. A recent research by Korea shows that the interval of the most intense/anxious smokers (e.g., during the breaks) can be as low as 4s.

without the detachable battery109 US19 336 21.B.102 te The internal short-circuit test cannot be

observed right after the drops and therefore cannot address the actual hazardous scenarios. In the past decade, a number of lithium battery incidents were caused by internal short-circuit due to mechanical stresses (e.g., dropping, manufacturing assembly process) could lead to catastrophic thermal runaway. The evaluation of relative change in open-circuit voltage has been implemented in other IEC product safety standards such as that used for the safety of smartphones, IEC 62368-1, seeing that no immediate fire or explosion does not ensure safety. Most field incidents took place after a few charging/discharging cycles following the mechanical stresses (e.g., drop).

Modify as follows:21.B.102electric heater must have sufficient mechanical strength to withstand drop, and compliance is checked by carrying out natural the drop test. - method 1 of IEC 60068-2-31, 3 times, each dropping in different postures– drop height is 1500 mm– after test, dangerous events such as rupture and ignition that do not comply with this standard shall not occurAn appliance with the most unfavourable consumable / consumable-load as specified in the manufacturer’s instructions shall be subjected to test free-fall – procedure 1, of IEC 60068-2-31 following pre-conditioning without consumables for 3 h at a temperature of -35 +0/-5 oC and then 1 h at a temperature of 25 ±5°C. It shall be dropped three times from a height of 1,5 m onto a concrete surface. The sample shall be positioned to vary the point of impact. The test is repeated on 3 additional samples. If the appliance is capable of operation following the drops, it is additionally tested under the conditions of Clause 11 at an ambient temperature 25 ±5°C.Following the above tests, the appliance shall not catch fire, leak fluid that is visible from the outside of the appliance enclosure or explode

and shall meet the requirements of Clauses 20 and 29 and B.22.103.1 and B.22.105 where short circuit of functional insulation will impair compliance with the standard. The open circuit voltages of the dropped cells and an additional reference (undropped) cell are periodically monitored during the following 24 hours. The relative change in the open circuit voltage difference shall not exceed 5%.The relative change in the open circuit voltage difference between a dropped cell and the reference (undropped) cell is calculated as follows:

|(OCV dropped(t=0)−OCV dropped(t=24h ))−(OCV undropped( t=0)−OCV undropped(t=24h))|OCV undropped(t=24h)?

DECISION: It was agreed to combine the NPs into a single NP under new PT 60335-2-120 with Co-convenorship by Mr. Yusuke Suzuki, JPNC, and Mr. Flore Chiang, USNC. An AC will be circulated to clarify the combination of the two NPs under a single PT 60335-2-120, to confirm the co-convenors, to identify the nominated experts from 61/6058/RVN and 61/6060/RVN, and to allow NCs to nominate additional experts.

The draft standard scope shall cover electrical safety of heaters for tobacco products and battery-operated vaping appliances supplied by batteries and related risks, but will not cover health effects of steam generated from tobacco units or nicotine.


The report to Council Board from CAB meeting 48, held virtually on 2020-11-09/10, as reported in SMB/7159/INF, was noted. It was also confirmed that from the side of the IEC there is no opposition from the ethical point of view (known danger to the health) on the development of standards addressing these types of appliances. It was also noted that the matter is still under discussion at the SMB level and it is expected to have feedback


by June 2021. In the report of TC 61 to SMB the essence of this decision and the request to SMB to clarify the approach to be taken by TCs when dealing with ethically sensible products will be noted.

Regarding the liaison request from ISO TC 126 and the presentation by Mr. Takatsugu Hyodo in 61(2020Web/ISOTC 126)86, TC 61 thanked Mr. Hyodo for the presentation proposing a Mode 4 liaison between ISO/TC 126/SC3, ISO/TC 126/WG22 and IEC/TC 61.
