Standards Development

Scope

This document specifies the general safety, design, construction, and performance requirements and testing of safety, control or regulating devices (hereafter referred to as controls) for burners and appliances burning one or more gaseous fuels or liquid fuels. This document is applicable to controls with declared maximum inlet pressure up to and including 500 kPa and of nominal connection sizes up to and including DN 250.

This document specifies general product requirements for the following controls:

— automatic shut-off valves;

— automatic burner control systems;

— flame supervision devices;

— fuel/air ratio controls/ supervision;

— pressure regulators;

— manual taps;

— mechanical thermostats;

— multifunctional controls;

— pressure sensing devices;

— valve proving systems;

— automatic vent valves.

This document applies:

— for control functions that are not covered by a specific control standard for burners and appliances burning one or more gaseous fuels or liquid fuels.

— for AC and DC supplied controls (for controls supplied by stand-alone battery, controls supplied by a battery which is part of a mobile application or controls supplied by a DC supply networksee Annex F).

— to reset functions used for reset from lockout, e.g. due to ignition failure or temperature cut-out in burners and appliances (see Annex H).

This document covers type testing only.

This document does not apply to mechanical controls for use with liquid fuels.

The protection against environmental impact in open air (i.e. capable of withstanding UV radiation, wind, rain, snow, dirt deposits, condensation, ice and hoar frost, earthquake and external fire) is not covered by this document.

This document establishes methodologies for the determination of a Performance Level (PL) (see Annex G).

This document gives guidelines for environmental aspects (see Annex I) and basic cyber security aspects (see Annex L).
