This proposal clarifies that the provisions concern any cable used in the entire vehicle, not only to those in the interior compartment, engine compartment and separate heater compartment. The proposal also clarifies that the regulation applies not only to electric cables, but also to cable sleeves or cable conduits and it updates the reference to paragraph 5.22. of ISO 6722-1:2011. Specifically, the proposal would apply testing to electric cables, cable sleeves, and cable conduits that exceed a length of 100 mm.

Text as adopted by the Working Party on General Safety Provisions (GRSG) at its 103rd session, clarifying the provisions on interior materials which shall be tested. It is based on document GRSG/2012/22, as amended at that session.

Proposal to improve and clarify provisions concerning the approval of interior materials, cables and insulation materials. The proposal adds new requirements for cable sleeves and conduits, modifies vertical testing requirements under Annex 8 to allow testing of small test samples and to clarify their fixation to the specimen holder, and adds a new Annex 10 on provisions for testing of electrical cables.

Proposal to reduce the administrative burden in obtaining approvals for electrical cables according to UN Regulation No. 118 by allowing for test reports and/or approvals established under ISO 6722:2006 (previous version of the current ISO 6722:2011) to remain valid.

Proposal to replace the term “roof” with the term “ceiling” throughout the text pursuant to Supplement 1 to the 02 series of amendments which modified the definition of “interior compartment” (previously “passenger compartment”) in paragraph 2.2. The definition replaced the term “roof” by “ceiling” in reference to the upper boundary surface of the compartment definition; however, the change in terminology was not reflected throughout the rest of the text. This proposal corrects that omission.
