This European Standard specifies the safety, construction and performance requirements for pressure regulators, (hereafter referred to as regulators), intended for use with gas burners and gas burning appliances using fuel gases of the 1st, 2nd and 3rd families. This European Standard covers type testing only. It also gives information necessary for the purchaser and user. This European Standard is applicable to regulators, which may be tested independently of these appliances, having a connection size up to and including DN 250 and a declared maximum working pressure up to and including 500 mbar. The methods of test given in this European Standard are intended for product type testing only. Tests intended for production testing are not specifically included. Regulators intended to be used on installations for the 3rd family gases are also covered by EN 13785 and EN 13786. This European Standard does not cover: a) pressure regulators connected directly to mains pipework or to a container that maintains a standard distribution pressure; b) pressure regulators intended for gas appliances to be installed out-of-doors and exposed to the environment; c) pressure regulators which use electrical auxiliary energy.
