Domestic cooking appliances burning gas. Safety. General
BS EN 30-1-1 is the standard that specifies the construction and performance characteristics as well as the requirements and methods of test for the safety and marking of freestanding and built-in domestic cooking appliances burning the combustible gases given according to the categories specified, and referred to as "appliances".
What appliances does BS EN 30-1-1 cover?
It covers the following types of domestic cooking appliances:
- Independent freestanding hotplates
- Independent built-in hotplates
- Independent hotplates and grills
- Table cookers
- Freestanding ovens
- Built-in ovens
- Freestanding or built-in grills
- Griddles
- Freestanding cookers
- Built-in cookers.
BS EN 30-1-1 applies to these appliances or their component parts, whether or not the component parts are independent or incorporated into a single appliance, even if the other heating components of the appliance use electrical energy (e.g. combined gas-electric cookers).
It includes requirements covering the electrical safety of equipment incorporated in the appliance that is associated with the use of gas. It does not include requirements covering the electrical safety of electrically-heated component parts or their associated equipment.
It does not apply to, outdoor appliances, appliances connected to a combustion products evacuation duct, appliances having a pyrolitic gas oven, appliances having covered burners which are not in conformity with the constructional requirements, appliances incorporating flame supervision devices and having an automatic ignition device for which the duration of the ignition attempt is limited by design or appliances equipped with a burner that is periodically ignited and extinguished under the control of an automatic on/off device.
