This document specifies the safety requirements for domestic gas cooking appliances. These appliances are freestanding, built-in or table-top and are intended to be used indoors. This document applies to the gas sections of the appliances and their component parts (e.g. combined gas-electric cooking appliances). This document does not apply to: a) electrical heated elements as part of the appliance; b) outdoor appliances; c) appliances supplied at pressures greater than the maximum pressure of the test gases; d) cook stoves, covered by the standards being developed in ISO/TC 285 In general, it does not take into account children playing with the appliance. NOTE 1   For requirements of electrical safety refer to the IEC 60335 standard series. NOTE 2   Attention is drawn to the fact that −     for appliances intended to be used in vehicles or on board of ships or aircrafts, additional requirements could be necessary; −     in many countries additional requirements are specified by the national health authorities, the national water supply authorities and similar authorities This document does not cover requirements relating to gas cylinders, their pressure regulators and their connections. This document does not cover requirements for gas installation.

Appareils de cuisson domestiques utilisant les combustibles gazeux -- Sécurité

Le présent document spécifie les exigences de sécurité des appareils de cuisson domestiques utilisant les combustibles gazeux. Ces appareils sont isolés, encastrés ou à poser sur table et sont destinés à être utilisés en intérieur.

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

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

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 International Standard 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 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 Annexes A and E.
This document covers type testing.

This document series ISO 21364 "Domestic gas cooking appliances – Safety" is structured as follows:

− Part 1: General requirements
− Part 21: Particular requirements for hobs, surface grills and griddles
− Part 22: Particular requirements for ovens and compartment grills

This document can be supplemented by the corresponding clauses of ISO/TS 21364-21:2021 and

ISO/TS 21364-22:2021.

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).

L'attention est attirée sur le fait que certains des éléments du présent document peuvent faire l'objet de

droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable

de ne pas avoir identifié de tels droits de propriété et averti de leur existence. Les détails concernant

les références aux droits de propriété intellectuelle ou autres droits analogues identifiés lors de

l'élaboration du document sont indiqués dans l'Introduction et/ou dans la liste des déclarations de

brevets reçues par l'ISO (voir www .iso .org/ brevets).

Introduction

Le présent document fournit des exigences générales pour la sécurité des appareils de cuisson

domestiques utilisant des combustibles gazeux.

Le présent document peut aussi être appliqué, dans la mesure du raisonnable, à des appareils non

traités par cette norme particulière et à des appareils conçus sur la base de principes nouveaux, auquel

cas des exigences supplémentaires peuvent être nécessaires.

Lorsqu’il n’existe pas de document spécifique pour un appareil, celui-ci peut être testé conformément

au présent document et à des essais complémentaires tenant compte de l’usage auquel il est destiné.

Les appareils à gaz utilisant des combustibles gazeux doivent supporter le type de gaz spécifié. D’autres

comités techniques de l’ISO, par exemple l’ISO/TC 193, Gaz naturel, traitent des essais et des propriétés

des gaz combustibles.

Il convient de noter qu'en raison des changements de propriétés du gaz combustible en fonction de sa

source/région d'origine, il existe actuellement certaines différences entre les réglementations dans

différentes régions; certaines de ces différences sont présentées dans les Annexes A et E.

Le présent document couvre les essais de type.

La législation locale du pays d'utilisation prévu doit être respectée (par exemple, les exigences en

matière de substances dangereuses, d'efficacité énergétique et d'efficacité des matériaux).

La présente série de documents ISO 21364 « Appareils de cuisson domestiques utilisant les combustibles

gazeux — Sécurité » est structurée comme suit:
— Partie 1: Exigences générales;

— Partie 21: Exigences particulières pour les tables de cuisson, grils et grils par contact;

— Partie 22: Exigences particulières pour les fours et compartim

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.

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 properties of fuel gas depending on its source/region of origin, certain

differences in regulations exist at present in different regions; some of these differ

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

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

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.
