BS EN 125:2010+A1 is a European Standard that specifies the safety, construction, and performance requirements for thermoelectric flame supervision devices, energized by a thermocouple intended for use with gas burners, gas appliances and similar use, hereafter referred to as "controls".
BS EN 125:2010+A1 is applicable to controls with declared maximum inlet pressures up to and including 500 kPa (5 bar) of nominal connection sizes up to and including DN 50 for use with one or more fuel gases in accordance with EN 437.
BS EN 125:2010+A1 not applicable to:
BS EN 125:2010+A1 on gas burning appliances is useful for:
A gas burner is a device that generates a controlled flame by combining a fuel gas, such as acetylene, natural gas, or propane, with an oxidizer, such as ambient air or supplied oxygen, and permitting ignition and combustion.
BS EN 125:2010+A1 provides you with the safety, construction, and performance requirements for thermoelectric flame supervision devices.
Compliance with the best industry guidance on thermoelectric flame supervision devices, BS EN 125:2010+A1, may help you optimize performance and standardise by setting the best safety requirements.
