Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
This document provides general requirements for safety of domestic gas cooking appliances.
This document can also be applied, so far as is reasonable, to appliances not mentioned in this
specific standard and to appliances designed on the basis of new principles, in which case additional
requirements may be necessary.
Where no specific document for an appliance exists, the appliance can be tested according to this
document and further tests which take into account the intended use.
Gas burning appliances using fuel gases need to withstand the type of gas which is specified. Other ISO
technical committees, e.g. ISO/TC 193, Natural gas, deal with the testing and properties of fuel gases.
Note that, due to the differing pro

Introduction
This International Standard provides general requirements for safety of domestic gas cooking
appliances.
This International Standard can also be applied, so far as is reasonable, to appliances not mentioned in
this specific standard and to appliances designed on the basis of new principles, in which case additional
requirements may be necessary.
Where no specific International Standard for an appliance exists, the appliance can be tested according
to this International Standard and further tests which take into account the intended use.
Gas burning appliances using fuel gases need to withstand the type of gas which is specified. Other ISO
technical committees, e.g. ISO/TC 193, Natural gas, deal with the testing and properties of fuel gases.
Note that, due to the differing properties of fuel gas depending on its source/region of origin, certain
differences in regulations exist at present in different regions; some of these differences are presented
in Annex E.
This International Standard covers type testing.
This International Standard series is structured as follows:
ISO 21364 Domestic gas cooking appliances – Safety
— Part 1: General requirements
— Part 21: Particular requirements for gas hobs, gas grills and gas griddles
— Part 22: Particular requirements for ovens and compartment grills
This Part 22 is to be used in conjunction with ISO/DIS 21364-1:2019.
This Part 22 supplements or modifies the corresponding clauses in ISO/DIS 21364-1:2019, so as to convert
that publication into the ISO standard: Particular requirements for ovens and compartment grills.
When a particular subclause of ISO/DIS 21364-1:2019 is not mentioned in this Part 2, that subclause
applies as far as is reasonable. When this standard states “Addition”, “Modification” or “Replacement”,
the relevant text in ISO/DIS 21364-1:2019 is to be adapted accordingly.
NOTE The following numbering system is used:
— subclauses, tables and figures that are numbered starting from 101 are additional to those in
ISO/DIS 21364-1:2019;
— unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including
those in a replaced clause or subclause;

Domestic gas cooking appliances — Safety —
Part 22:
Particular requirements for ovens and compartment grills
1 Scope
This Part of ISO 21364 specifies particular requirements for safety, construction and materials of
domestic gas ovens and compartment grills. For general requirements for safety, construction and
materials of gas ovens and compartment grills the Standard ISO/DIS 21364-1:2019 applies.
This Part covers the following gas cooking appliances:
— ovens with natural or forced convection;
— pyrolytic ovens and pyrolytic compartment grills;
— compartment grills
being built-in, part of a cooking appliance or table top.
— oven accessories
It does not cover gas ovens and compartment grills intended for outdoor use and/or commercial use
as well as electrical heated elements as part of the appliance. It does also not cover appliances with
automatic burner control systems.
NOTE 1 For requirements of electrical safety refer to the IEC standards.
NOTE 2 Attention is drawn to the fact that
— for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be
necessary;
— in many countries additional requirements are specified by the national health authorities, the national water
supply authorities and similar authorities.
This International Standard does not cover requirements for gas installation.
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.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes
nationaux de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est
en général confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l'ISO participent également aux travaux.
L'ISO collabore étroitement avec la Commission électrotechnique internationale (IEC) en ce qui
concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier de prendre note des différents
critères d'approbation requis pour les différents types de documents ISO. Le présent document a été
rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2 (voir www
.iso .org/ directives).
