Proposal prepared by the GRSG Secretariat pursuant to discussions of document GRSG/2016/24. The proposal aims 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 improve and clarify provisions concerning the approval of interior materials, cables and insulation materials. The proposaladds 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. The experts from Finland, France and Germany agreed that the change from ISO 6722:2006 to ISO 6722-2011 does not impact the degree of safety and, therefore, the test reports or approvals established under the older version of the ISO standard shall remain valid.

Proposal to delete the volume and shape limits of the fume cupboard described in Annex 8 (Test to determine the vertical burning rate of materials) and replace these with the performance specification that the fume cupboard dimensions shall not affect the test results. The proposal also sets a minimum sample size of 375 × 170 mm under paragraph 3.1. of Annex 8.

Proposal to clarify the scope and the application of the regulation. The proposal clarifies that the regulation applies to “the burning behaviour of electric cables and cable sleeves or cable conduits used in the vehicle” 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.

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.
