This European Standard specifies safety, construction, and performance requirements
and testing 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 first, second or

Controls to which this European Standard applies include the following:
-
— automatic shut-off valves;
-
— automatic burner controlsystems;
-
— flame supervision devices;
-
— gas/air ratio controls;
-
— pressure regulators;
-
— manual taps;
-
— mechanical thermostats;
-
— multifunctional controls;
-
— pressure sensing devices;
-
— valve proving systems;
-
— zero pressure regulators.
The methods of test given in this standard are intended for product type testing.
For DC supplied controlsAnnex H applies.
NOTE 1 When no particular control standard exists, the control can be tested according to this standard and further tests taking into account the intended use.
NOTE 2 This European Standard should be used in conjunction with the specific control standard (see Bibliography).
