Draft text under discussion within the LNG task force concerning automatic valve requirements on LNG tanks.

Draft text under discussion within the LNG task force as of its 11th session proposing amendments to document GRSG/2013/7 concerning automatic valve provisions.

Review of four international LNG standards (ISO 12991-2012, NFPA 52-2013, SAE J2343-2008 and AS 2739-2009) for requirements related to LNG tank shut-off devices. The report discusses specific aspects and challenges of mounting two valves in series on same LNG line. The emphasis is on using two components, a manual valve and an automatic valve mounted in series on
the LNG supply line to shutoff the flow.

Proposal to establish uniform provisions for gangway barriers in vehicles of Classes I and A, including a proposed 100N force limit for moving such barriers out of the way.

Proposal to clarify that the regulation applies to the type approval of anti-theft devices if fitted in the vehicle (and therefore is not meant to render such devices compulsory in vehicles).

Proposal to clarify the transitional provisions of the 03 series of amendments to UN Regulation No. 46, including provisions for extensions of approvals to the 03 series of amendments,for approval of devices to the 02 series, and provisions for aftermarket devices.

Proposal to allow the installation of exterior mirrors with automatic pivoting functions on the passenger side of a vehicle in order to enable designs that offer a better field of vision for the driver during turning maneuvers.

Proposal to clarify the provisions on the extended field of vision on heavy goods vehicles across different mirror classes. The text would require assessment of normal and extended fields of vision using a single mirror adjustment and to allow for the loss of up to 10% of the close-proximity field of vision in such configurations.

Proposal to introduce more stringent requirements for rear underrun protection devices.

Proposal to introduce type-approval provisions for “valve control at stop-start” into the regulation on LPG equipment. The proposal would allow tank valves stay open in a commanded stop-start phase as it is the case for the idling phase of non-stop-start vehicles. These provisions are similar to those for UN R110 on CNG vehicles.

Proposal to introduce type-approval provisions for fuel selection systems into the regulation on compressed natural gas-powered vehicles.

Proposal to introduce type approval provisions for “valve control at stop-start”.
