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.

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 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).

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).

GRPE to consider the proposal for corrigendum to document ECE/TRANS/WP.29/2019/45..

Proposals to amend or supersede the proposal in document GRSG-116-05. Liquid Gas Europe opposes the proposal to add an odorant in the n-pentane.

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

AEGPL views on the proposal to align Regulation No.115 to the new WLTC test cycle, defined in the GTR 15 and in the Commission Regulation (EU) 2017/1151 and later modifications.

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 require marking of extension numbers on accessories relevant to the UN R67 bonfire test (e.g., multivalve, pressure relief valve, pressure relief device) in order to prevent/prohibit the misuse (in container configurations) of these accessories. The proposal includes provisions for components where such marking is impractical based upon text drawn from UN R46.

1. Document GRSG/2017/22 proposed by Turkey raised concerns regarding the location on the vehicle of the filling unit and a limitation of the service life of LPG containers
2. In order to prevent a proliferation of different service-life specifications, AEGPL proposes a fixed mandatory service live of 10 years.

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.

Proposal to allow for the approval of systems using non-seamless double and single wall tubes subject to testing for high pressure and high resistance to pressure pulses. The proposal would also add general test requirements for LPG fuel lines and couplings based on ISO Standard 15500 for compressed natural gas equipment.

In GRSG/2017/10, Poland proposes requirements for the LPG tank and its accessories. AEGPL notes that UN R67 requires a specific bonfire test of the container equipped with specific configurations of accessories which includes markings to indicate the extension number of each accessory corresponding to each configuration. In order to ensure that the user knows whether an accessory can be fitted with a specific container, AEGPL proposes to require marking the extension number on the accessories relevant to the bonfire test (multivalve, pressure relief valve and pressure relief device) in order to prevent/forbid the fitting of any accessory not approved for use in each container configuration. This alternative proposal to that in GRSG/2017/10 would imply a new marking requirement for accessories, but would avoid the proliferation of accessory type-approval numbers and increase in paperwork.

Proposal to introduce tolerances for dish, bayonet, and acme filling units in order to reduce risks of misuse in connecting these filling units with nozzles.

Proposal to restrict the application of CO2 specific emission limits only to NMHC and CO emissions (back-to-back comparison of NOx and PM to apply under the regulation in any case). The proposal also aligns the text where applicable with the intent of paragraph 2.3.15.: “R49 original emission limits” means the emission limits as defined in Regulation No. 49 to which the original engine system was approved."

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.

Amendments to the proposal as presented in document GRPE/2016/12.

Proposal to insert 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 amend UN R67 to allow for limited flows of petrol into the LPG tank of dual fuel vehicles, taking into account comments received during the 109th GRSG session.

Presentation on the proposal to allow for limited flows of petrol into the LPG tank of dual fuel vehicles.

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

Proposal to limit reporting requirements to the tested (or parent) vehicles in the type approval communication form by deleting the requirement to communicate CO2 emissions and power figures for each specific vehicle0. For vehicle types where the retrofit system is qualified (i.e. other than parent vehicles), the current model requires the communication of a calculated CO2 factor as well as of the specific CO2 emissions in natural gas mode. Since the specific CO2 emissions in gas mode are calculated by applying the CO2 factor to the emissions in petrol mode, communication of only the CO2 factor is sufficient to establish the CO2 emissions in gas mode of any vehicle type, when required.

Version 7 of the working draft regulation for HDDF retrofit systems under the custodianship of the AEGPL as revised during the 32nd GFV/HDDF group sessions.

In document GRSG/2013/29, the AEGPL proposed 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. At the 105th GRSG session, Germany requested a more detailed test procedure. Therefore, this proposal responds to the German request, improves certain descriptions of requirements, and provides comments to justify the various provisions.
