This International Standard is applicable to pressure-vacuum valves and devices to prevent the passage of flame protecting marine vessel systems, including cargo tanks, which may be subject to explosive gas/vapour and/or to gas/vapour pressure or vacuum beyond the design parameters of the system/tank. This International Standard specifies the minimum requirements for performance and testing. It also specifies design and in-service performance criteria, operational testing and maintenance requirements. Design or manufacturing in accordance with this International Standard does not imply suitability for any given installation, it indicates that certain minimum requirements have been considered and that information necessary for determination of suitability is provided to the buyer of the equipment.

The flame test procedures of this standard are based on the requirements of ISO 16852:2016.

NOTE 1 Minimum requirements for devices to prevent the passage of flame are found in the International Maritime Organization (IMO) "International Convention for the Safety of Life at Sea, as amended" (SOLAS), Chapter II-2, Regulation 4, and IMO Maritime Safety Committee (MSC) Circular No. 677 (MSC/Circ. 677), "Revised Standards for the Design, Testing and Locating of Devices to Prevent the Passage of Flame into Cargo Tanks in Tankers", as amended.
