Report of the EGOLF TC1 meeting held on 26th March 2015 at CSI S.p.A., Viale Lombardia 20, 20021 Bollate (MI), Italy

1 Opening of the meetingThe chair of TC1, Rupert Ehrlenspiel, welcomed members to the meeting and expressed appreciation to CSI for hosting the week of EGOLF meetings and for the excellent tour and dinner in Bergamo. He extended thanks also to CSI sponsors TREMA Verfahrenstechnik GmbH (suppliers custom designed gas cleaning equipment), J.F. Amonn S.p.A (intumescent paints) and Troterolo & Re S.p.A (security doors).

2 To approve the draft agenda, N579rev2The agenda was approved, subject to additional item on status and review of EGOLF recommendations and agreements, further to discussions in Plenary on 25th March. This will be taken under Item 9.

3 To approve the report of the previous meeting held on 13th October 2014, N572The report was approved.

4 To consider any matters arising

- Cable test method in EN 13501-6M Łukomski (ITB) reported that Europacable were not interested in sponsoring this course and so this item is closed for the time being.

- Gaiker reaction to fire videosMembers had all received a link to these videos which are available on You Tube.

5 To note discussions on reaction to fire matters in CEN/TC127/WG4 Although he had not been able to attend the last meeting of WG4, H Rademacher reported that all comments on prEN 16733:2014 (Reaction to fire tests for building products - Determination of a building products propensity to undergo continuous smouldering) had now been considered. It is expected that a formal vote will take place and that the standard will be available toward the end of the year or early in 2016. (Post meeting note from the Chairman: The EC wants the smoldering classification to be included in prEN 16733, rather than EN 13501-1. This means that delays in the timetable might occur).

The SG had been informed by Silvio Messa that WG4 would notify ISO TC 92 SC1 about the EGOLF position paper EGP01 (EN ISO 1182 review of non-combustibility test method) in order for them to take this into consideration when reviewing ISO EN reaction to fire methods later this year. P Howard (BM Trada) offered to check the situation with Christine Lukas whom he will be seeing next week.

Action P Howard6 Reaction to fire standards, N581rev1

This paper was noted.

7 TC1 helpdesk reports, N495rev5, N548rev2 & N576Only one item was raised (2013-07), since all others had either been closed or are dealt with under Item 10 of agenda.

8 TC1 Activities

8.1 Workshop: evaluation of uncertainty of measurement in context of European reaction to fire test methods, N586This workshop had attracted a large number of delegates (21). H Rademacher reported that Bart Sette had done a good job at facilitating the event. His report is available on the TC1 meeting folder (N586).

8.2 Harmonisation coursesThe Chairman expressed appreciation to H Rademacher for all his work on EGOLF reaction to fire courses. The latest to be held was given in the German language in week beginning 16 th March at MPA NRW. This had attracted thirty participants, including a number from the host lab. and three non-members. If additional courses in German are required, Mr Rademacher said he could plan these quite quickly.

Meeting attendees who had attended reaction to fire courses in English at SP and Kiwa BDA in November 2014 and March 2015 confirmed that these had been very helpful and informative.

8.3 EGOLF reaction to fire round robins

Five year planThe Chairman pointed out that German accreditation bodies require a five year plan from labs. for round robin tests and that it would be helpful to know EGOLF's future schedule. The next round robin is the SBI test, which is to be launched shortly. Members agreed with him that this could be followed by another EN ISO 1182 round robin, including an evaluation of organic content according to EN 13820, which is an option in EN 13162.

For note SG

Reference documents on EGOLF websiteThe SG will include a reference on future agendas to the location of round robin reports and guidelines etc. which are held in the EGOLF RR reports and guidelines pages of the Publications folder and therefore not duplicated on the TC1 meeting folder. She was also asked to consider introducing a separate numbering system for such documents.

Actions SG

EGOLF round robin guidelines, N580The round robin guidelines will be updated to include reference to accreditation bodies in Chapter 5 – Ownership of Results, in order to clarify that participating member labs. may show (but not hand over) confidential reports to their national accreditation bodies.

EGOLF SBI round robin, N569rev1Nick Neumann of MFPA Leipzig, the lab. which is organising this round robin in collaboration with SP Sweden, presented the proposed plan of action and budget which had been endorsed by Executive in January. The following comments were raised:

- The materials (e.g. particle boards) available on the market may belong to the same fire reaction class but are often still different e.g. concerning the values required for particle board substrates in EN 13238, footnote to Table 1. It would therefore be preferable to have a central material; it is not considered EGOLF's task to ascertain if materials on the market are different. If there is a scattering of results, the round robin will be of no use. It is recommended therefore that the particle boards are provided by one manufacturer only.

- It was recommended that a comparison of the 2004 round robin results be included in this proposal

- In addition to the EGOLF contribution of €17,700, Executive should be asked to approve payment of extra €11,120 (i.e. estimated €370 participation fee per participant, which excludes shipping which must be paid for on an individual lab. basis)

- Before participating labs. validate their evaluation software using EGOLF validation files and document SM7 "prEN 13823 SBI reaction to fire test – Procedures to be used for validation of SBI 'data analysis' software", it will be necessary for the organisers to ensure the Word document is up to date and also to check and validate the software. This may cause some delays to launch of the round robin.

In conclusion, the following actions were agreed:

1) The validation process will follow the schedule in the proposal. The first step is for Nick Neumann and colleagues on the round robin steering group to revise the proposal and then consider and resolve all the issues to do with updating of SM7 document and checking and validation of data files for software evaluation.

Action RR steering group

2) Nick will provide the SG with a zip file containing the EGOLF Word document and validation files for uploading to the EGOLF website.

Action N Neumann/SG

3) The following members agreed to take responsibility for running the EGOLF CD and comparing this with the three main software providers – wfrgent and IBS (Fire Instrumentation & Research Equipment (FIRE) software), CSTB (FTT software) and MFPA Leipzig (Taurus software)

Actions N Neumann/E van Wesemael (wfrgent) & M Eichhorn-Gruber/G Créach

4) The round robin organisers will order particle boards from one batch Action MFPA Leipzig and SP

5) An option will be for participating labs. to include a third test on a steel substrate. A Steen-Hansen suggested that it would be easy to do this and so include it in round robin proposal – not for the round robin report but to be kept in another file for attention of the standards committee.

For note/action: RR organisers & participating labs.3

6) Nick Neumann will revise the RR proposal, including increase in EGOLF contribution, for endorsement by Executive at the earliest opportunity, preferably before their next meeting in June.

Action N Neumann/Executive

7) The SG will add a new point on the Autumn agenda of TC1 about collecting data for tests on substrates alone where problems are found concerning the borders of EN 13238 Conditioning procedures and general rules for selection of substrates. Where it is proved that the standard is too strict, EGOLF will bring information to the attention of the standards committee.

Actions SG/TC1 Chairman

8.4 Proposed industry round robin (SH02 WG10) – Cables to EN 50399:2011), SH02 N614The SG reported that the maximum number of labs. (30) had already submitted expressions of interest for this round robin which is being organised by SP, Sweden on behalf of SH02 WG 10 Cables. The EGOLF SG will provide the central secretariat for the round robin, an activity which will be undertaken outside of her normal duties. Participants will include notified and candidate fire testing laboratories and manufacturers with the facilities to perform fire tests according to EN 50399. The launch is expected in the latter part of 2015. Minimum requirements for participation are to be defined by SH02 WG10.

9 EGOLF publications: Recommendations and position papers9.1 Two recommendations have been published since the meeting in October – PIR and PUR flat linear

products classification EN 13501-1 (EGR 86) and definition test specimen according to CEN/TS 1187 tm1 (EGR 88).

9.2 Status of new position papers, EGP 02 & SH02 N594rev2Dieter Brein, the new convenor of CEN TC 127 WG5 has responded to SG's request to include the latter on agenda of their next meeting. Richard Zammitt offered to present this to the WG and will forward any corrections to this paper for attention of SG. (Post meeting note: R Zammitt has reported that WG5 were in agreement with EGP 02 and will look to revise TS 1187 and 13501-5 at the next opportunity).

Donatas Lipinskas of FRC in Lithuania is able to provide test evidence to demonstrate problems with the mineral wool. Since evidence will also be required from other labs., members are requested to send information direct to Mr Lipinskas for presentation in the Autumn.

9.3 Status of EGOLF EGRs and EGAsIn the context of Plenary discussions concerning the need for clarification about the status of EGRs and EGAs (whether or not they are all mandatory and up to date with latest versions of the standards etc.) it was agreed to commence the process for reaction to fire guidance as follows:

4

Hendrik Rademacher and Bernd Restorff will take one standard each (EN 13823 and 11925-2 respectively) and identify those Recommendations and Agreements which are still needed as they stand now, those which can be combined and those which are in need of updating, as well as an indication of their status (Agreement or Recommendation). The deadline to complete this task is 30th June.

Action H Rademacher/B Restorff

Following the exercise, TC1 will decide which of these documents should be considered mandatory as opposed to best practice guidance. This information will then be fed back to Plenary.

Action H Rademacher2014-04 application rules flexible sheetsThere were a lot of items being addressed at once with this. A few members were concerned about the allowance to change layers in the field of application. The reason wfrgent need this is that their client has been to another lab where a lot less testing was required to cover a large field of application. This is worrying and the test reports and classifications have been requested to see how this was achieved. The document will be re-written to simplify it.

2015-05 span calibration CO2 analyser for SBITechnically there was no concern about this in TC1; one member suggested that in ISO 17025 there is a statement that we can deviate from standards if it improves accuracy. One lab has FTT equipment and they have to span with 8%. Standard states 5-10%. It was also stated that the uncertainty of the calibration gas certificate is improved with a lower percentage of CO2. There were no objections to BM TRADA or others using 3% for CO2 span calibration.

Group 2 (Roofing Subgroup) Reporter – Richard Zammitt

Draft EGR: Use of brands in tm1 of CEN TS 1187

N566 was discussed, the draft recommendation was agreed by the subgroup as representing “good practice” to address potential repeatability (results within a given laboratory) and reproducibility (results between different laboratories) issues that had been identified as part of the EGOLF round robin exercise. A draft recommendation, based on N566, has been prepared (N566rev1).

N566rev1

Draft EGP: Burnt length of EPS insulation in a test specimen according to CEN/TS 1187, test method 1 (see Helpdesk Item below)

The draft Position Paper (N574) on interpretation of “burnt” or “damaged” material for EPS insulation to test method 1 was discussed. The EGOLF round robin had proved that different laboratories interpret differently whether EPS has “burnt” (combustion or pyrolysis) or is “damaged” (including melting). To achieve consistency in reporting within EGOLF, the group agreed that the draft position paper recommendation: to consider “internal fire spread” to mean “internal damage” was a pragmatic solution. However, in Classification Reports it would still be necessary to report in accordance with EN 13501-5 and TS 1187.

Conclusion: The draft Position Paper can be published but shall be sent to CEN TC 127 WG5 and SH02 for endorsement/agreement by those bodies as well.

2015-01 Damaged length definition, CEN/TS 1187 tm 2 – to be discussed with draft EGP above “Burnt length of EPS insulation… CEN/TS 1187 tm1 (N574)"

Neither SP (originator) nor BDA (commentator) were able to attend TC1 and so the subgroup had to discuss item N583 and N583 Annex 1 without further explanation. VTT were however present and confirmed that this item came about from the recent (November 2014) harmonization course on “t2” run at SP.

The group agreed unanimously (8 laboratories present) that the proposed improved wording of SP for damaged length definition (see N583 revision 1) was an improvement to aid with consistency of interpretation, however, the group was also unanimous that the second photograph from SP in N583 revision 1 was not consistent with the now improved definition of damaged length. All members of the subgroup agreed with the BDA position that the roof cover in the second picture was “clearly damaged” (melted material exposing the reinforcement layer in the roof cover) beyond the point indicated and labeled as “damaged”.

CONCLUSION

This item (N583 revision 1) to be returned to SP and ask them to “improve” the second photograph in N584 revision 1 so it is consistent with the suggested wording and with the photographs below from Nordtest Project 1572-02:2004 (see below). At that point an EGOLF recommendation shall be issued with the new improved definition of damaged length.

2015-02 CEN/TS 1187 test 1 and extension to test and glowing combustion criteria - to be discussed with draft EGP above "Burnt length of EPS insulation…CEN/TS 1187 tm1 (N574)”

BDA (originator) were not present, but Fire Research centre of Lithuania (commentator) weree able to explain the N584 revision 1 document. The problem is that it is possible to run a t1 test for 60 minutes and find „internal glowing combustion“ in mineral wool insualtion such that the test has „failed“ according to the classification criteria of EN 13501-5. However, it is also possible (at customer request) to extend the test to „any longer time“ and it has been observed by several laboratories that a test „failing“ at 1 hour (for glowing combustion) will „pass“ at 2 hours, particularly for mineral wool insulation. Although the test report is required to state the duration of test, the Classification Report indicating „BROOFt1“ will not state the duration of test.

CONCLUSION

An EGOLF recommendation is needed to ensure that if the t1 test has been extended by the test sponsor (see clause 4.7.4 of TS 1187) then a footnote shall appear beneath the „BROOFt1“ classification in the Classification Report stating the actual time of test (eg 2 hours, 3 hours etc etc) in order to achieve the Classification.

A draft Recommendation has been prepared (N584rev2).
