Scope: This standard specifies the safety, constructional and performance requirements for zero pressure governors, hereafter referred to as zero governors, intended for use with gas appliances. It also gives the test procedures for evaluating these requirements and information necessary for the purchaser and user. This standard applies to zero governors for gas-burning appliances that may be used and tested independently of these appliances. These zero governors are suitable for one or more of the fuel gases of the 1st, 2nd and 3rd families, at inlet pressures up to and including 200 mbar. This standard does not cover: a) zero governors connected directly to distribution pipework or to a container that maintains a standard distribution pressure; b) zero governors intended for gas appliances to be installed out-of-doors and exposed to the environment. This standard covers type testing only.
