Introduction
This standard recognizes the safety level specified by CEN/TC 58 and is regarded as a horizontal
standard dealing with the safety, construction and performance of controls for burners and appliances
burning gaseous and/or liquid fuels and to their testing.
The general requirements for controls are given in this document, and methods for classification and
assessment for new controls and control functions are given in EN 14459:2015 (see Figure 1). EN 126
(see Figure 1) specifies multifunctional controls combining two or more controls and Application
Control Functions, one of which is a mechanical control function. The requirements for controls and
Application Control Functions are given in the specific control standard (see Figure 1, control
functions).
Figure 1 — Interrelation of control standards
This European Standard should be used in conjunction with the specific standard for a specific type of
control, (e.g. EN 88-1:2011, EN 88-2:2007, EN 125:2010, EN 126:2012, EN 161:2011+A3:2013,
EN 257:2010, EN 298:2012, EN 1106:2010, EN 1643:2014, EN 1854:2010, EN 12067-2:2004,
EN 16304:2013 and EN 16340:2014), or for controls for specific applications. This standard can also be
applied, so far as reasonable, to controls not mentioned in a specific standard and to controls designed
on new principles, in which case additional requirements can be necessary. EN 14459:2015 provides
methods for classification and assessment of new control principles.
Primarily in industrial applications it is common practice to rate the safety of a plant based on values
describing the likelihood of a dangerous failure. These values are being used to determine Safety
Integrity Levels or Performance Levels when the system is being assessed in its entirety.
CEN/TC 58 standards for safety relevant controls do go beyond this approach, because for a certain life
time for which the product is specified, designed and tested a dangerous failure is not allowed at all.
Failure modes are described and assessed in greater detail.
Measures to prevent from dangerous situations are defined. Field experience over many decades is
reflected in the CEN/TC 58 standards. Requirements of these standards can be considered as proven in
practice.
To be able to provide values for the parameters that are needed for the determination of a Safety
Integrity Level (SIL) or of a Performance Level (PL), Annex J and Annex K of this document specify a
possible methodology to derive values for the relevant parameters from the requirements of this
European Standard. Only controls that conform to the relevant CEN/TC 58 control standard can be
assessed for SIL or PL classification according to these Annexes.
It cannot be presumed that any Safety Integrity Level or Performance Level assessment alone would
imply that requirements of a CEN/TC 58 standard have been met.
1 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 safety accessories and pressure accessories with a product of
the maximum allowable pressure PS and the volume V of less than 600 000 kPa · dm (6 000 bar · L) or
with a product of PS and DN of less than 300 000 kPa (3 000 bar).
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).
