Introduction
This document is intended to be used in conjunction with EN 13611:2019.

EN 13611:2019 recognizes the safety level specified by CEN/TC 58 and is regarded as a horizontal

standard dealing with the safety, construction, performance and testing of controls for burners and

appliances burning gaseous and/or liquid fuels.

The general requirements for controls are given in EN 13611:2019, and methods for classification and

assessment for new controls and control functions are given in EN 14459:2021 (see Figure 1).

EN 126:2012 (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

EN 13611:2019 should be used in conjunction with the specific standard for a specific type of control (e.g.

EN 88-1:2022, EN 88-2:2022, EN 88-3:2022, EN 125:2022, EN 126:2012, EN 161:2022, EN 257:2022,

EN 298:2022, EN 1106:2022, EN 1643:2022, EN 1854:— , EN 12067-2:2022, EN 16304:2022,

EN 16340:2014, EN 16678:2022 and EN 16898:2022), or for controls for specific applications.

EN 13611:2019 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 14459:2021 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.
Under preparation. Stage at the time of publication: FprEN 1854:2022.

Measures to prevent from dangerous situations are defined. Field experience over many decades is

reflected in the CEN/TC 58 standards. Requirements of EN 13611:2019 can be considered as proven in

practice.

This document refers to clauses of EN 13611:2019 or adapts clauses by stating “with the following

modification”, “with the following addition”, “is replaced by the following” or “is not applicable” in the

corresponding clause.

This document adds clauses or subclauses to the structure of EN 13611:2019 which are particular to this

document. Subclauses which are additional to those in EN 13611:2019 are numbered starting from 101.

Additional Annexes are designated as Annex AA, Annex BB, Annex CC, etc. It should be noted that these

clauses, subclauses and Annexes are not indicated as an addition.

If by reference to EN 13611:2019 the term “control” is given, this term should be read as “tap”.

European foreword

This document (prEN 1106:2020) has been prepared by Technical Committee CEN/TC 58 “Safety and

control devices for burners and appliances burning gaseous or liquid fuels”, the secretariat of which is

held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1106:2010.

This document has been prepared under a standardization request given to CEN by the European

Commission and the European Free Trade Association, and supports essential requirements of

EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this

document.

This document is intended to be used in conjunction with EN 13611:2019. This document refers to

clauses of EN 13611:2019 or adapts clauses by stating “with the following modification”, “with the

following addition”, “is replaced by the following” or “is not applicable” in the corresponding clause.

This document adds clauses or subclauses to the structure of EN 13611:2019 which are particular to

this standard. It should be noted that these clauses and subclauses are not indicated as an addition.

Subclauses which are additional to those in EN 13611:2019 are numbered starting from 101. Additional

Annexes are designed as Annex AA, BB, CC, etc.

The following significant technical changes compared to the previous edition have been incorporated in

this document:

a) the Scope is enlarged to maximum inlet pressures up to and including 50 kPa (500 mbar);

b) alignment with EN 13611:2019;
c) updating of Clause 2, Normative references;

d) requirements from EN 126:2004 relating to “Open and closed position of a tap”, “Compensation

means for taps” and “Spring effect in taps” were included (refer to 6.101.8 to 6.101.10);

e) requirements and tests relating to durability of elastomers in contact with gas (7.8 of this

document) are now totally aligned with EN 13611:2019, 7.8.
