Foreword

This document (CEN Guide 18:2021) has been prepared by Technical Committee CEN/SFG_U “Sub

Forum Gas Utilization”, the secretariat of which is held by AFNOR.

This document is intended for the use of Technical Committees writing product and/or supporting

standards in the field of gas appliances and fittings.

It gives guidelines for the development of standards to support the Essential Requirements of the Gas

Appliances Regulation (EU) 2016/426.

As a response to the increased number of standards dealing with gas appliances and fittings not

published in the Official Journal of the European Union, the relevant Gas Technical Committees have

undertaken publication of guidelines for the implementation of Essential Requirements of GAR in

European gas product standards, supplementing the CEN/CENELEC Internal Regulations, Part 3:2019,

which sets out general principles and requirements for all European Standards.

1 Scope

This document presents guidelines for the implementation of Essential Requirements of Gas Appliances

Regulation (EU) 2016/426 into hEN candidates for citation in the OJEU.

This document gives guidance that is additional to the CEN/CENELEC Internal Regulations, Part 3:2019,

when this is necessary owing to the special requirements of gas appliances and fittings.

This document is intended for the drafting of gas appliances and fittings standards.

2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

CEN/CENELEC Internal Regulations, Part 3:2019, Principles and rules for the structure and drafting of

CEN and CENELEC documents (ISO/IEC Directives Part 2:2018, modified)

EN 1672-2:2005+A1:2009, Food processing machinery — Basic concepts — Part 2: Hygiene requirements

EN 60335-2-102:2016, Household and similar electrical appliances — Safety — Particular requirements

for gas, oil and solid-fuel burning appliances having electrical connections (IEC 60335-2-102:2004,

modified)

EN 60730-1, Automatic electrical controls — Part 1: General requirements (IEC 60730-1)

EN ISO 13732-1, Ergonomics of the thermal environment — Methods for the assessment of human

responses to contact with surfaces — Part 1: Hot surfaces (ISO 13732-1)
3 Terms and definitions

For the purposes of this document, the terms and definitions given in the CEN/CENELEC Internal

Regulations, Part 3:2019 apply.
4 General principles

The CEN/CENELEC Internal Regulations, Part 3:2019 should be used in conjunction with this document

when preparing a new standard dealing with gas appliances and fittings or revising an existing one.

In general, the standards should not repeat or paraphrase the text of other reference standards;

however, for better understanding of standards, it is acceptable to repeat a basic definition, concept or

the scope of the standard.
5 Principles to be considered during drafting process
5.1 Checklist to be considered during drafting process

At least the following items of the standard should be checked before filling out the Annex ZA:

1) Clear follow up of comments on former assessment sometimes by the TC;

2) Information indicating significant changes in the foreword of the revised or amended standard;

3) It is essential to follow rules for the use of verbal forms so that a clear distinction can be made

between requirements (shall), recommendations (should), permissions (may), possibilities and

capabilities (can);
---------------------- Page: 7 ----------------------
SIST-V CEN Guide 18:2021
CEN Guide 18:2021 (E)
4) All normative references dated;

5) State of the art for fulfilling the Essential Requirement of the GAR to be taken into account;

6) For incorporated fittings the relevant ER have to be taken into account;

7) Adequate method/test to verify each requirement (e.g. visual inspection is not sufficient in all

cases…);
8) Clear separation between requirements and test conditions in the same clause;

9) No requirements to the manufacturer, test laboratory, installer, etc. in a product standard;

10) No items concerning quality control, etc. in a product standard;

11) Lex Specialis: The rational use of energy essential requirement laid down in point 3.5 of Annex I to

this Regulation does not apply to appliances covered by a measure adopted pursuant to Article 15 of

Directive 2009/125/EC;

12) Requirements for parts/material coming into contact with food and water are essential, no

reference to Regulation 1935/2004 as all relevant Regulations have to be applied;

13) No mixture of “instructions”, GAR is using installation instructions for the installer, instructions for

use/maintenance/servicing (intended for the user) and technical documentation (which shall

make it possible to assess the product);

14) No “country of destination” or “Official language(s)” as GAR is only talking of “languages easily

understood by consumers, appliance manufacturers, the market surveillance authorities and other

end-users” in clauses relevant for Annex ZA;
15) Check the numbering of the standard.
5.2 Implementation of Essential Requirements

For the implementation of Essential Requirements of Gas Appliances Regulation (UE) 2016/426, the

following Table 1 gives some guidelines.

PRELIMINARY OBSERVATIONS:
1. The essential requirements laid down in this
Regulation are compulsory.
2. The essential requirements are to be
interpreted and applied in such a way as to take
into account the state of the art and current
practice at the time of design and manufacture as
well as technical and economic considerations
which are consistent with a high degree of energy
efficiency and of health and safety protection.
