Proposal to correct references to para.6.15. which was renumbered as para. 6.17. by Supplement 15 to 01 series amendments (document WP.29/2018/18).

Proposal to align the requirements of IP protection grades to latest IEC standard and recognize ISO 20653 as a valid alternative and to correct duplicate paragraph numbers 6.17.10.8 in separately adopted amendments by changing one of the amendments to 6.17.10.9.

Proposal from the European Liquefied Petroleum Gas Association (AEGPL) to add values for the aerostatic pressure to be reached during the external leakage test of Class 0 components, in line with the provisions of paragraph 5.3.

Proposal from AEGPL to revise the text proposed by Germany (GRSG/2012/18) (to clarify approvals of hoses and couplings) in order to preserve the possibility to type-approve flexible hoses separately and prior to hose assembly approval.

Proposal to introduce new provisions into Regulation No. 67 for preventing the flow of liquefied petroleum gas (LPG) into the petrol or diesel tank, and vice versa in order to address a potential safety risk in bi-fuel or dual-fuel vehicles.

Proposal to amend UN R67 to allow for limited flows of petrol into the LPG tank of dual fuel vehicles.

Proposal for new safety provisions with regard to LPG systems having hydraulic interconnections with the petrol or diesel fueling system through which inter-flows of fuels may occur.

Proposal for new safety provisions with regard to LPG systems having hydraulic interconnections with the petrol or diesel fueling system through which inter-flows of fuels may occur.

Proposal to establish procedures for the approval of non-seamless gas tube(s), gas tube(s) made of materials other than copper, stainless steel, and steel with corrosion-resistant coating, and their couplings in Liquefied Petroleum Gas (LPG) vehicles provided they can withstand the applicable tests according to Annex 15.

Proposal presented as an alternative to the previous proposal from Poland (GRSG/2017/10) to require manufacturers to mark the approval extension number on any accessories relevant to the bonfire test (multivalve or, when approved separately, pressure relief valve (discharge valve) and pressure relief device) so that the fitting of any accessory not on the list of approved configurations (Table 3 in the appendix of Annex 2B) will be prevented/forbidden. This solution would imply a new requirement in Annex 2A for the marking of the accessories fitted to the containers.

In the absence of complete harmonization with ISO 11439, this proposal recommends that Table 6.4 of UN R110 should be amended by the following for CNG-1 designs:

1. Delete A.17, A.25, and A.7 since they do not match the tests specified in paragraph 7.5 on Cylinder design qualification tests
2. Add A.15 and A.6 since they do match the tests specified in paragraph 7.5 on Cylinder design qualification tests
3. Add A.24 because paragraph 6.9 on Fire protection requires all PRDs on all cylinder types to comply with A.24.

Proposal to insert type (item 1.1.) and pressure classification (item 1.2.) in the communication form (Annex 2B).

Proposal to amend the transitional provisions of UN Regulation No. 67 and clarify the validity of type approvals according 01 series of this regulation for components not affected by modifications introduced by 02 series of amendments.

Proposal to correct the references to paragraph 6.15. which were renumbered as paragraph 6.17. by Supplement 15 to 01 series of amendments (document WP.29/2018/18).

Proposals aims to align the requirements of IP protection grades to the latest IEC standard and to recognise ISO 20653 as a valid alternative, which is more appropriate and focused on automotive applications.
