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

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.

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.
