Session 106 | Geneva | 5-9 May 2014
8. Regulation No. 110 (Specific components for CNG)
GRSG-106-07 | UN Regulation No. 110 – CNG/LNG vehicles Proposal to regulate the discharge direction of pressure relief devices (PRD) on CNG containers in response to a fire accident in the Netherlands in which the PRD produced a long horizontal jet flame for several minutes posing a risk to other road users and surrounding buildings.
GRSG-106-15 | UN Regulation No. 110 – CNG/LNG vehicles Note to open a discussion concerning the gas-cylinder periodic inspection requirements of Annex 3 of UN R110.
GRSG-106-24 | Proposals for amendments to Supplement 1 to the 01 series of amendments to UN Regulation No. 110 Supplement 1 to the 01 series included requirements for the positioning of LNG tanks. While the Netherlands believes that mounting the LNG fuel tank 200mm above the road surface is broadly adequate; this proposal aims to ensure that the fuel tank cannot, under any normal driving or stationary working situations, come into contact with the ground. The new wording provides more definitive conditions, including the possibility of a vehicle having one or more flat tires as well as for those vehicles that have ‘kneeling’ capability or variable suspension, both of which lower the frame of the vehicle closer to the ground.
GRSG-106-29 | UN R110 Annex 3 & ISO 11439 “High pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles” Presentation highlighting concerns regarding the separate development of UN R110 and ISO 11439 provisions resulting in diverging test protocols and other differences.
GRSG-105-31 | Comments on the draft Supplement 1 to the 01 series of amendments to Regulation No. 110 The draft supplement 1 to the 01 series of amendments to UN R110 (pending before the November WP.29 session) introduces type-approval provisions for vehicles equipped with liquefied natural gas propulsion systems. In this document, Germany signals its intention to prepare substantial revisions concerning its safety provisions.
GRSG-106-27 | Proposal for amendments to UN Regulation No. 110 Proposal to require an exterior protection on cylindrical gas tanks. Under the current regulation, such exterior protection may be fitted at the discretion of the manufacturer. The intention is to increase protection against corrosion of cylinders in response to a corroded cylinder explosion in Germany.
