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.

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

European foreword

This document (prEN 16898:2020) 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 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 or B, which are an integral part of this

document.

Introduction

The generic 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 14459:2015, Clause 1 up to and

including 7.13 (see Figure 1).

The requirements for controls are given in the specific control standard (see Figure 1).

Multifunctional Controls (MFC) according to EN 126:2012 with two or more controls and Application

Control Functions, e.g. the Gas Shut-off Control Function, being inherently multifunctional controls.

Each control integrated in the MFC meets the applicable requirements of the relevant control

standard(s). In addition, EN 126:2012 covers requirements for the safety related interactions between

the different devices.

This control standard refers to clauses of EN 13611:2019 or adapts it 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.

1 Scope

This document specifies the safety, design, construction, and performance requirements and testing for

gas filters for burners and appliances burning one or more gaseous fuels.
This document is applicable to:

— gas filters with declared maximum inlet pressure up to and including 600 kPa, of nominal

connection size up to and including DN 250 for use with one or more fuel gases in accordance with

EN 437:2009;

— gas filters specified as pressure accessories as defined by EU Directive 2014/68/EU (see Annex F).

NOTE 1 For pressure accessories, the requirements of EN 13611:2019, Annex F also apply.

NOTE 2 Requirements for pressures above 500 kPa are considered in subclause 6.3.1 by referring to

EN 13611:2019, Annexes F to H.

This document is not applicable to gas filters that are connected directly to mains pipe-work or to a

container that maintains a standard distribution pressure.
