Proposal defines the working pressure for an LNG tank to be the primary relief valve setting (paragraph 4.4.), without stating a minimum value of the said relief valve. If a vehicle has an on-board tank with a primary relief valve that opens at a lower pressure than that at which the filling station is set to stop, the primary relief valve will open during refueling and this is an obvious safety risk.

Proposes the addition of design qualification tests also will harmonize with ISO 15500-13:2012, and the North American CSA/ANSI PRD 1 (2020).

Update paragraphs to be in line with the requirements of ISO15500 and NGV3.1 (industry standards for CNG).

Proposal aims to prevent the installation of the filling unit under the body of M1 vehicles.

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 from GRSG to resolve issues with the application of provisions to vehicle configurations for which BSIS may not work correctly (e.g. because of the vehicle body, the vehicle use) to allow more flexibility for system design and facilitate introducing automated brake functions.
