Standards Development

Scope

This European Standard 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 European Standard 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 European standard specifies general product requirements for the following controls:

— automatic shut-off valves;

— automatic burner control systems;

— flame supervision devices;

— gas/air ratio controls;

— pressure regulators;

— manual taps;

— mechanical thermostats;

— multifunctional controls;

— pressure sensing devices;

— valve proving systems;

— automatic vent valves.

This European standard 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.

This European Standard applies also for pressure accessories with a product of the maximum allowable pressure PS and the volume V of less than 600 000 kPa · dm3 (6 000 bar · L) or with a product of PS and DN of less than 300 000 kPa (3 000 bar) and which are subject to a maximum allowable pressure > 50 kPa.

This European Standard applies to safety accessories. Specific requirements for pressure accessories and safety accessories are given in Annex F.

This European Standard does not cover aspects of manufacturing processes, e.g. proof tests of pressure accessories.

This European Standard applies for AC and DC supplied controls (for controls supplied by stand-alone battery system, battery systems for mobile applications or systems which are intended to be connected to DC supply networks controls see Annex I).

This European Standard is applicable to reset functions used for reset from lockout, e.g. due to ignition failure or temperature cut-out in burners and appliances (see Annex M).

This European Standard establishes methodologies for the determination of a Safety Integrity Level (SIL) and the determination of a Performance Level (PL) (see Annex J, Annex K and Annex L).

This European Standard gives guidelines for environmental aspects (see Annex N).

This European Standard 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 (see IEV 441-11-05:2005), earthquake and external fire) is not covered by this standard.

This European Standard should be used in conjunction with the specific control standard (see Bibliography).

Purpose

In the latest revision EN 13611:2019 the standard was aligned to the new Gas Appliance Regulation – valid since April 2018. Due to the time an alignment to the Pressure Equipment Directive (PED) was not considered in the latest version of EN 13611. In order to receive a listing in the Official Journal of the European Union under GAR and PED, an amendment to EN 13611:2019 – aligning the standard with the PED as well – is needed.
