It also describes the test procedures for checking compliance with these requirements and provides information necessary for the purchaser and user. This standard applies to pressure governors for gas burning appliances of nominal connection size up to and including DN 50 which may be used and tested independently of these appliances. These governors are suitable for one or more of the fuel gases of the Ist, 2nd and 3rd families, at inlet pressures up to and including 200 mbar. This standard does not cover: a) governors connected directly to the mains pipework or to a container that maintains a standard distribution pressure; b) governors intended for gas appliances to be installed outdoors and exposed to the environment; C) governors which use electrical auxiliary energy.
