GRSG | Session 123 | 28 Mar-1 Apr 2022

37. GRSG considered the proposal for Supplement 1 to the 05 series of amendments to UN Regulation No. 110 (CNG and LNG vehicles) in GRSG-123-02-Rev.1 (superseding ECE/TRANS/WP.29/GRSG/2022/12) to overcome the lack of design qualification tests within UN Regulation No. 110 to determine that a temperature activated Pressure Relief Device (PRD) would consistently activate in a timely manner. GRSG agreed to resume discussion at its October 2022 session based on a new official proposal drafted by a Task Force coordinated by the expert of NGVA Europe. GRSG also agreed, in case a new proposal was not submitted by the deadline for official documents, that the secretariat would distribute GRSG-123-02-Rev.1 with an official symbol.
