This European Standard deals with the safety, construction and performance requirements of safety, control or regulating devices and sub-assemblies or fittings (hereafter referred to as controls) for burners and gas-burning appliances using fuel gases of the 1st, 2nd or 3rd families and to their testing.
This European Standard is to be used in conjunction with the specific control standard.
When no specific control standard exists, the control can be tested according to this standard and further tests taking into account the intended use.
Controls to which this European Standard applies include the following:
- Automatic shut-off valves;
- Burner controls
- Flame supervision devices;
- Gas/air ratio controls;
- Pressure Governors;
- Manual taps;
- Mechanical thermostats;
- Multifunctional controls;
- Pressure sensing devices;
- Valve proving systems;
- Zero governors
The methods of test given in this standard are intended for product type testing. Tests intended for production testing are not specifically included.
