Please see Appendix F of this bulletin regarding designated responsibility for the subject product categories. Please note that proposed requirements are of a tentative and early nature and are for review and
20、comment only. Current requirements are to be used to judge a product until these requirements are published in final form. PRODUCTSANDINDUSTRIESAFFECTED BYTHE PROPOSAL UL requests your assistance in identifying other products or industries that might be affected by the requirements contained in this
21、 bulletin. UL suggests that all suppliers or customers for these products and industries be made aware of these requirements prior to their proposed effective date. Also, please forward your suggestions to UL so that these products and industries may be identified in future bu I let ins. RATIONALE U
22、L proposes a revision to paragraphs 12.1 and 12.4 of UL 913, the Standard for Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division 1, Hazardous (Classified) Locations. The paragraphs address requirements for the separation of intrinsically safe and nonintri
23、nsically safe internal wiring. The purpose of the revision is to align the wording of paragraphs 12.1 and 12.4 with the wording of the same requirements used in UL 60079-1 1, the Standard for Electrical Apparatus for Explosive Gas Atmospheres - Part 11 : Intrinsic Safety “i“ . While UL certifies int
24、rinsically safe apparatus using UL 91 3 for North American “Division“ Locations, and international standards such as UL 60079-1 1 for “Zone“ Locations, these are both Hazardous Locations. Therefore, the requirements on internal wiring should be aligned. Unless specifically requested to do so, UL wil

As such, this series of safety standards will replace ANSI/UL 2279, Electrical Equipment for Use in Class I, Zone O, 1 and 2 Hazardous (Classified) Locations - representing the latest evolution in ULs efforts towards more closely harmonizing the US Zone requirements with the applicable IEC 60079 s
42、eries of Zone requirements, along with furthering the US position internationally under the IECEx Scheme. As part of these US efforts associated with the IECEx Scheme, as of October 2002, UL is now accredited as an Accepted Certification Body (ACB) and Assessment & Testing Laboratory (ExTL) under th
43、e IECEx Scheme. This provides the US its first and only such accredited body able to accept and issue Assessment and Test Reports (ATRs) for certification in 22 countries across Asia Pacific, Europe and North America that are actively participating under the Scheme.
