Over deze norm
This European Standard specifies the safety, construction and performance requirements for pressure regulators and pneumatic gas/air ratio pressure regulators (zero pressure regulators are included as a special type of pneumatic gas/air ratio pressure regulators), intended for use with gas burners, gas appliances and similar use, hereafter referred to as ‘pressure regulators’. This European Standard covers type testing only. This European Standard applies to pressure regulators of nominal connection sizes up to and including DN 250 with declared maximum inlet pressures up to and including 50 kPa (500 mbar) for use with one or more fuel gases in accordance with EN 437, pressure regulators which use auxiliary energy, pneumatic gas/air ratio pressure regulators (zero pressure regulators are included as a special type of pneumatic gas/air ratio pressure regulators), which function by controlling a gas outlet pressure in response to an air signal pressure (or air signal differential pressure) and/or to a furnace pressure signal, but gas/air ratio pressure regulators which change an air outlet pressure in response to a gas signal pressure (or gas signal differential pressure) are not excluded.
