29. The expert from France proposed incorporating new provisions concerning refrigeration systems for cooling the cargo compartment which are connected to the compressed natural gas (CNG) and/or liquefied natural gas (LNG) system (ECE/TRANS/WP.29/GRSG/2016/16). The expert from Japan raised concerns about risks of increased filling cycles of CNG cylinders due to a higher filling frequency. He suggested supplementing the proposed provisions with additional test conditions to not exceed the maximum number of filling cycles of CNG cylinders (GRSG-111-18). A number of experts were of the opinion that the number of filling cycles of CNG cylinders specified in the test requirements of UN Regulation No. 110 would be sufficient to cover the higher filling frequencies. GRSG did not support the additional test conditions proposed by Japan.

30. GRSG adopted ECE/TRANS/WP.29/GRSG/2016/16 as amended below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2017 sessions, as draft Supplement 6 to the 01 series of amendments to UN Regulation No. 110.

Paragraph 18.1.7.1., replace “compartiment des marchandises” by “compartiment de chargement”.
Paragraph 18.5.1.3., subparagraphs (b) and (c), replace “compartiment des marchandises” by “compartiment de chargement” and “contrôle électronique” by “contrôle électronique GNC/GNL” (two times).

31. At its previous session, GRSG had discussed the need to update the reference to the ISO standard in paragraph 2.2. of Annex 4J. The expert from the Netherlands volunteered to submit a concrete proposal for amendments for consideration at the next GRSG session.

32. The expert from ISO presented an overview of the activities of his organization on specific aspects for gaseous fuels (GRSG-111-25). He introduced GRSG-111-02 with the rationale of all amendments proposed to UN Regulation No. 110 in document ECE/TRANS/WP.29/GRSG/2016/22 superseding ECE/TRANS/WP.29/GRSG/2016/6. GRSG welcomed GRSG-111-03 listing the copies of all ISO standards referenced to in UN Regulation No. 110 on CNG/LNG vehicles. A number of experts raised a concern on the dynamic referencing of international standards and expressed their preference for a static referencing, mainly for legal purposes. GRSG reviewed the document and agreed on the need to adopt the proposal as a new 03 series of amendments and to insert transitional provisions triggered of the 1 September. The expert from France asked for more detailed information on each of the proposed amendments, especially on the level of stringency and their impact on technical services. The expert from CLEPA underlined the need to also insert transitional provisions for existing type approvals and sufficient lead time for suppliers to upgrade them.

33. Following study reservations by the experts from Germany, France and CLEPA, GRSG decided to resume consideration of the proposal at its next session in April 2017 based on a revised document to be submitted by ISO. The Chair invited all experts to send their written comments on GRSG-111-02-Rev.1 in due time to the experts from ISO or NGV Global.

34. The expert from the Netherlands introduced GRSG-111-20 aimed at correcting an error in the definitions related to the manual valve. GRSG noted general support and agreed to resume consideration of this subject at its next session in April 2017. The secretariat was requested to circulate GRSG-111-20 with an official symbol.

35. GRSG noted GRSG-111-31, tabled by the International Association of Fire and Rescue Services (CTIF), on the need to take into account during the development of UN regulations necessary interventions and actions of and risks for rescuers, especially on the identification of propulsion and energy storage systems in vehicles. The Chair invited interested experts to send their comments to the authors of the presentation (see e-mail addresses on the last page).
