This document specifies the safety, design, construction as well as performance requirements and testing for pneumatic pressure regulators and safety devices for burners and appliances burning one or more gaseous fuels, hereafter referred to as ‘pressure regulators’. This document is applicable to: - pressure regulators with declared maximum inlet pressure above 50 kPa up to and including 500 kPa, of nominal connection size up to and including DN 250 for use with one or more fuel gases in accordance with EN 437; - pressure regulators incorporating safety devices; - pressure regulators and safety devices which use auxiliary energy; and - stand-alone pressure regulators or pressure regulators equipped with a control device for maximum or minimum gas pressure. This document is not applicable to: - pressure regulators that are connected directly to mains pipe-work or to a container that maintains a standard distribution pressure; - pressure regulators intended for gas appliances to be installed in the open air and exposed to the environment.

This document specifies the safety, design, construction, and performance requirements and testing of electronic pressure and/or flow rate regulators (hereafter referred to as ‘regulators’) for burners and appliances burning one or more gaseous fuels. This document is applicable to regulators with declared maximum inlet pressure up to and including 500 kPa and of nominal connection sizes up to and including DN 250. This document is applicable to - regulators which use auxiliary energy, - regulators, which function by controlling a gas outlet pressure or a gas flow rate, - regulators with a modular structure specified as a unit, - regulators intended for gas appliances to be installed indoor or in the open air and exposed to the environment. This document does not cover regulators connected directly to a gas distribution network or to a container that maintains a standard distribution pressure.

This European Standard specifies the safety, construction and performance requirements for automatic vent valves for use with gas burners, gas appliances and similar use, hereafter referred to as ‘valves’. This European Standard is applicable to: - valves with declared maximum inlet pressures up to and including 500 kPa (5 bar) of nominal connection sizes up to and including DN 100 for use with one or more fuel gases in accordance with EN 437:2003+A1:2009; - electrically operated valves; - valves actuated by fluids where the control valves for these fluids are actuated electrically, but not to any external electrical devices for switching the control signal or actuating energy; - valves fitted with open position indicator switches. NOTE Provisions for final product inspection and testing by the manufacturer are not specified.

This document 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 regulator), intended for use with gas burners, gas appliances and similar use, hereafter referred to as ‘pressure regulators’. This document is applicable to - pressure regulators with declared maximum inlet pressures up to and including 50 kPa (500 mbar) of nominal connection sizes up to and including DN 250 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, which function by controlling a gas outlet pressure in response to an air signal pressure, air signal differential pressure, and/or to a furnace pressure signal (zero pressure regulators are included as a special type of pneumatic gas/air ratio pressure regulator), - gas/air ratio pressure regulators, which change an air outlet pressure in response to a gas signal pressure or a gas signal differential pressure. This document does not cover - pressure regulators connected directly to gas distribution network or to a container that maintains a standard distribution pressure, - pressure regulators intended for gas appliances to be installed in the open air and exposed to the environment, - mechanically linked gas/air ratio controls, - electronic gas/air ratio controls (EN 12067 2).

This document specifies the safety, design, construction and performance requirements and testing for automatic shut-off valves with or without modulating control functions (hereafter referred to as ‘valves’) for burners and appliances burning one or more gaseous fuels according to EN 437:2003+A1:2009. This document is applicable to valves with declared maximum inlet pressures of more than 500 kPa (5 bar) and up to and including 6 300 kPa (63 bar). This document is applicable to - electrically operated valves and to valves actuated by fluids including the pilot valves for these fluids if actuated electrically and including release valves, but not to any external electrical devices for switching the actuating energy; - automatic shut-off valves where the flow rate is controlled by external electrical signals proportional to the applied signal. This document is not applicable to valves specifically designed for use in transmission and distribution networks. NOTE Provisions for final product inspection and testing by the manufacturer are not specified.
