What are BS EN 88-1 - Pressure regulators and associated safety devices for gas appliances about?
BS EN 88 is a series on pressure regulators and associated safety devices for gas appliances. Pressure regulators and associated safety devices for gas appliances is a valve that controls the pressure of a fluid or gas to the desired value, using negative feedback from the controlled pressure.
BS EN 88-1 specifies the safety, construction, and performance requirements for pressure regulators and pneumatic gas/air ratio pressure regulators, intended for use with gas burners, gas appliances. BS EN 88-1 provides the best industrial guidance on Pressure regulators for inlet pressures up to and including 50 kPa.
BS EN 88-1 is applicable to:
- Pressure regulators with declared maximum inlet pressures up to and including 50 kPa (500m bar) 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
- Gas/air ratio pressure regulators change an air outlet pressure in response to a gas signal pressure or a gas signal differential pressure.
Note: BS EN 88-1 does not cover:
- Pressure regulators connected directly to the 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).
Who is BS EN 88-1 - Pressure regulators and associated safety devices for gas appliances for?
BS EN 88-1 on Pressure regulators and associated safety devices for gas appliances that inlet pressures is useful for:
- Gas equipment manufacturers
- Regulator manufacturers
- Gas regulator distributors
- Design engineers
- Quality control personnel
Why should you use BS EN 88-1 - Pressure regulators and associated safety devices for gas appliances?
Regulators are used for gases and liquids and can be an integral device with a pressure setting, a restrictor, and a sensor all in one body, or consist of a separate pressure sensor, controller, and flow valve. BS EN 88-1 provides construction, and performance requirements for pressure regulators and pneumatic gas/air ratio pressure regulators. BS EN 88-1 states that the regulator is used in combination with a safety shut-off device upstream of the regulator the following alternative external leakage test can be used for external leakage carry out the test with 1,5 times the withstand pressure at inlet and outlet and with a pressure of 1,5 times the difference between withstanding pressure and maximum outlet pressure on the atmospheric side of the working diaphragm (including the safety diaphragm if any).
BS EN 88-1 intended for use with gas burners, gas appliances. BS EN 88-1 helps to improve the quality and ensure associated safety devices for gas appliances that inlet pressures up to and including 50 kPa. With compliance and obedience to BS EN 88-1, you can enhance the efficiency or efficacy of machinery and manufacture a standardized product of high-quality. Using BS EN 88-1 you can specify the safety, construction, and performance requirements for pressure regulators and pneumatic gas/air ratio pressure regulators, intended for use with gas burners, gas appliances.
