    Abstract - (Show below) - (Hide below)

    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 provides additional information for the purchaser and user. This European Standard is applicable to regulators that may be tested independently of gas burners and gas-burning appliances, which have a declared working pressure from above 500 mbar up to and including 5 bar.This European Standard is also applicable to regulators incorporating safety devices. NOTE 1For safety accessories and pressure accessories, the requirements of EN 13611:2000, Annex F also apply.NOTE 2Regulators conforming to EN 88-2 fulfil also the requirements of EN 88-1.Regulators intended to be used on pipe work installations for third family gases are also covered by EN 13785 and EN 13786.This European Standard is not applicable to:a)pressure regulators that are connected directly to mains pipe-work or to a container that maintains a standard distribution pressure;b)pressure regulators which use electrical auxiliary energy.pressure;b)pressure regulators which use electrical auxiliary energy.
