Committee Statement

CommitteeStatement:

In paragraphs 5.1.8 and 5.1.8.1, the technical committee is clarifying the intent of the label date.

There are three key aspects to the proposed addition of the new 5.1.9:

1) Added text is similar to 7.1.4 as a new paragraph under 5.1 on product label requirements. Thefocus of this new paragraph is compliance with the product label (marking) requirements fromANSI/ISA 12.12.01. The rationale for this is because ANSI/ISA-12.12.01 includes requirements forproduct label (marking) in addition to performance requirements. Without the addition of this newparagraph, NFPA 1801 could be mistakenly assumed to only require compliance with theperformance requirements in ANSI/ISA-12.12.01.

2) Expand the referenced Division 2 certification requirement to include Class II, Division 2, GroupsF and G, in addition to the existing Class I, Division 2 requirements. The rationale for this is becauseexposure to Class II explosive dust atmospheres (such as coal, carbon black, charcoal, coke, flour,grain, wood, and plastic dusts) is a concern for this equipment, in addition to exposure to Class Iexplosive gas atmospheres. Compliance with such Class II, Division 2 requirements mostly involvesuse of a NEMA Type 12 or better enclosure.

3) Include reference to the T3 and T4 temperature classifications between T3 and T6 that havesuffixes, in addition to the existing reference to T3, T4, T5 and T6. The rationale for this is becauseT3A, T3B, T3C and T4A are permitted temperature classifications between T3 and T6 in bothANSI/ISA-12.12.01 and in the NEC.

The technical committee believes that although the standard specifies percentage of poweravailable percentage, this means little to the user. Section 6.1.2 requires that the thermal imager

shall be capable of continuously operating for a minimum of 120 minutes in TI BASIC mode. If themanufacturer supplies a power source that is capable of operating for a minimum of 120 minutes orgreater it should be able to provide the estimated level of power associated with each of the foursegments in time. It should be noted that the operating time of a fully charged power source currentlysupplied in many thermal imagers far exceeds 120 minutes.

Committee Statement

CommitteeStatement:

The technical committee is adding the term "service life" to provide further clarification to 5.2.7.

There are three key aspects to the proposed new text for 5.2.8:

1) The new added text is similar to 7.1.4 as a new paragraph under 5.2 on user informationrequirements. The focus of this new requirement is compliance with the user information(manufacturer’s instruction manual) requirements from ANSI/ISA 12.12.01. The rationale for this isbecause compliance with ANSI/ISA-12.12.01 includes requirements for user information(manufacturer’s instruction manual), in addition to performance requirements. Without the addition ofthis new paragraph, NFPA 1801 could be mistakenly assumed to only require compliance with theperformance requirements in ANSI/ISA-12.12.01.

2) Expand the referenced Division 2 certification requirement to include Class II, Division 2, Groups Fand G, in addition to the existing Class I, Division 2 requirements.

Committee Statement

CommitteeStatement:

The technical committee observed that the original intent of the document was to require videorefresh rates of 30Hz or higher. This was discussed and included in the earlier drafts of the standardunder development, but was not included in the final version. A low refresh rate camera will pass theNFPA 1801 image quality tests since all the NFPA testing is done on static images. A refresh rate ofless than 30Hz can make navigation more difficult and may lead to firefighter disorientation.

Committee Statement

CommitteeStatement:

The technical committee believes that there are three key aspects to this proposed newrequirement.

1) The added is text similar to 7.1.4 as a new paragraph under 6.1 on Design requirements. Thefocus of this new requirement is compliance with the design (construction) requirements fromANSI/ISA 12.12.01. The rationale for this is because compliance with ANSI/ISA-12.12.01 includesrequirements for design (construction) in addition to performance requirements. Without the additionof this new paragraph, NFPA 1801 could be mistakenly assumed to only require compliance with theperformance requirements in ANSI/ISA-12.12.01.

2) The referenced Division 2 certification requirements have been expanded to include Class II,Division 2, Groups F and G, in addition to the existing Class I, Division 2 requirements. The rationalefor this is because exposure to Class II explosive dust atmospheres (such as coal, carbon black,charcoal, coke, flour, grain, wood, and plastic dusts) is a concern for this equipment, in addition toexposure to Class I explosive gas atmospheres. Compliance with such Class II, Division 2requirements mostly involves use of a NEMA Type 12 or better enclosure.

3) A reference is included to the T3 and T4 temperature classifications between T3 and T6 that havesuffixes, in addition to the existing reference to T3, T4, T5 and T6. The rationale for this is becauseT3A, T3B, T3C and T4A are permitted temperature classifications between T3 and T6 in bothANSI/ISA-12.12.01 and in the NEC.

Committee Statement

CommitteeStatement:

NFPA 1801 requires that the thermal imager shall be provided with a method of attaching thethermal imager to the user, and the method of attachment shall not degrade the function orperformance of the thermal imager but nowhere in the standard is a test conducted for this.

It is important to have have the requirement in 6.1.9 as most thermal imagers are intended to beattached to the user, possibly by a retractable lanyard or strap rather than to just be hand held. It isunderstood that there are several methods of attachment and it would be counterproductive to theprocess to have a manufacturer submit all specimens with all the attachment variations for all thetesting. It is recommended that each means of attachment that a manufacturer offers be provided tothe testing lab and that the testing lab simply attach them to the thermal imager as intended and thento the person to determine if either the attachment point on the thermal imager and/or the method ofattachment degrades the function or performance of the thermal imager.

Committee Statement

CommitteeStatement:

The technical committee believes that there are three key aspects to this proposed revision:

1) The text of paragraph 7.1.4 to focus on performance (test) requirements from ANSI/ISA 12.12.01.The rationale for this is because, while compliance with ANSI/ISA-12.12.01 includes requirementsfor product label, user information and design, in addition to performance requirements, this chapteronly addresses performance requirements. Separate proposals are being made to add similar textunder Chapters 5 and 6 so that it cannot be mistakenly assumed that only compliance with theperformance requirements in ANSI/ISA-12.12.01 is required.

2) Expand the referenced Division 2 certification requirement to include Class II, Division 2, GroupsF and G, in addition to the existing Class I, Division 2 requirements. The rationale for this is becauseexposure to Class II explosive dust atmospheres (such as coal, carbon black, charcoal, coke, flour,grain, wood, and plastic dusts) is a concern for this equipment, in addition to exposure to Class Iexplosive gas atmospheres. Compliance with such Class II, Division 2 requirements mostly involvesuse of a NEMA Type 12 or better enclosure.


The TC also believes that locking features that rely on the use of special tools to limit the ability toperform simple tasks such as battery replacement are often ignored by users that have not read thesmall print hidden in the product user guide. However the certification bodies are much morecomfortable with this approach and adherence is recognized within the high risk Petrochemical /Mining Industries.

Committee Statement

CommitteeStatement:

The technical committee believes that cycling the temperature between 49C and 60C is notcreating enough of a temperature differential to truly test the product. In addition, the long dwelltimes and multiple cycles make the test very difficult to run from a practical perspective. The testcannot be completed in a work day.

The 60C soak at 4 hours provides more than ample time for the camera to come to equilibrium andprovides the desired temperature stress.
