scope:

This standard provides information on the safe installation and use of gas fuelled spark ignition and dual-fuel engines

These Procedures apply to spark ignition and compression ignition engines of both the reciprocating and rotary type, either stationary or potable, for both continuous and standby duties, excluding engines used to vehicle and marine propulsion. Primarily they cover the essential safety aspects of the engineering, installation and operation of engines using 1st, 2nd or 3rd family gases as fuel. They apply to gas pipework and control systems downstream of, and including, the engine manual isolation valve, at an upstream MOP > 0.5 bar.
