This International Standard specifies the design, minimum safety and functional requirements, inspection and testing procedures for LNG dry-disconnect/connect coupling served for LNG hose bunkering system intended for use on LNG bunker ship, tank truck and shore-based facility etc. This standard is not applicable to hydraulically operated quick connect/disconnect coupler (QCDC) used for hard loading arm since it has been stipulated in ISO 16904. Based on the current technology of industrial manufacturing, the size of coupling from DN25 to DN200 is to be considered and contained within this standard at the development period.

The scope of this standard includes the following five elements.

1)    General requirements: basic design principle, design parameters, functional requirements, internal valve, protective cap, handle;

2)    Materials: body of coupling, welding, bolting, spring, seals;

3)    Interface type and dimensions: Ends termination of receptacle, dimensions;

4)    Marking: manufacturer and international standard information;

5)    Testing: test conditions, test arrangement, general requirements, verification testing, production testing.
