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 differences are presented
in Annex A.
This document covers type testing.
This document series is structured as follows:
ISO 21364 Domestic gas cooking appliances – Safety
— 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 is to be used in conjunction with ISO/TS 21364-1:2021.
This document is designed to be used in combination with ISO 21364-1. Together, they establish the
full requirements as they apply to the product covered by this document. Where needed, this document
adapts ISO 21364-1 by stating in the corresponding clause:
- “with the following modification”;
- “with the following addition”;
- “is replaced by the following”;
or
- “is not applicable”.
In order to identify specific requirements that are particular to this document, that are not already
covered by ISO 21364-1, this document may contain clauses or subclauses that are additional to the
structure of ISO 21364-1.
To ensure global relevance of this document, the differing requirements resulting from practical
experience and installation practices in various regions of the world have been taken into account. The
variations in basic infrastructure associated with appliances have also been recognized, some of which
are addressed in ISO/TS 21364-1:2021, Annex E and ISO/TS 21364-22:2021, Annex A. This document
intends to provide a basic framework of requirements that recognize these differences.

with reference gas according to the corresponding Table in ISO/TS 21364-1:2021, Annex A at normal
pressure. Hob burners, if any, are not operated.
The oven burner is operated up to an average temperature of 230 °C in the centre of the oven. This
temperature is maintained, if this temperature cannot be obtained the control is set to full rate. The
grill burner is operated at full rate.
After 1 h of operation or after the burner was shut off by an overheating safety device, if any, the
temperatures are measured.
7.3.4 Temperatures of accidentally touchable surfaces
7.3.4.1 General
During the accidentally touchable surfaces temperature tests, if the front and side surfaces are flat,
temperature rises are measured using the probe of Figure 1 or any other measuring device giving the
same results. For non-flat surfaces fine wire thermocouples are used.
The probe is applied with a force of (4 ± 1) N to the surface in such a way that the best possible contact
between the probe and the surface is ensured. The temperature is read after stabilization of the
measuring device.
The probe can be held in place using a laboratory stand clamp or similar device.

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 soumis à essai
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 à l’Annexe A.
Le présent document couvre les essais de type.
La présente série de documents est structurée de la manière suivante:
ISO 21364, Appareils de cuisson domestiques utilisant les combustibles gazeux — Sécurité
— Partie 1: Exigences générales;
— Partie 21: Règles particulières pour les tables de cuisson à gaz, grils à gaz et grils par contact à gaz;
— Partie 22: Exigences particulières pour les fours et compartiments de grillage.
Le présent document doit être utilisée conjointement avec l’ISO/TS 21364-1:2021.
Le présent document est prévu d’être utilisé conjointement avec l’ISO/TS 21364-1:2021. Ensemble, ils
établissent l’ensemble des exigences qui s'applique au produit couvert par ce document. Le cas échéant,
ce document adapte l'ISO 21364-1 en indiquant dans l'article correspondant:
— «avec la modification suivante»;
— «avec l'ajout suivant»;
— «est remplacé par»;
ou
— «n'est pas applicable».
Afin d'identifier les exigences spécifiques qui sont particulières au présent document, qui ne sont pas
déjà couvertes par l'ISO 21364-1, ce document peut contenir des paragraphes ou sous-paragraphe qui
s'ajoutent à la structure de l'ISO 21364-1.
Pour assurer la pertinence globale de ce document, les exigences différentes résultant de l'expérience
pratique et des pratiques d'installation dans diverses régions du monde ont été prises en compte.
Les variations de l'infrastructure de base associées aux appareils ont également été reconnues, dont
certaines sont traitées dans l’ISO/TS 21364-1:2021, Annexe E et l’ISO/TS 21364-1:2021, Annexe A. Le
présent document vise à fournir un cadre de base d'exigences qui reconnaissent ces différences.

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;

7.3.102.3 Temperatures of accidentally touchable surfaces of forced convection ovens and
compartment grills
Ovens and compartment grills that can be operated in the forced convection mode are tested in the
same way as ovens or grills with natural convection, but with an average temperature of 180°C at the
centre of the compartment.
7.3.102.4 Temperatures of accidentally touchable surfaces of pyrolytic ovens and
compartment grills
7.3.102.4.1 Requirement
The contact temperatures of the exterior surfaces of an appliance provided with self-cleaning oven or
self-cleaning grill feature shall not exceed those specified in 7.3.102, Table 101 and ISO/DIS 21364-1:2019,
7.3.2, Table 4 (except the temperatures for knobs and grips) when the appliance is operated in the self-
cleaning mode.
Burn hazard potential shall be determined on all surfaces specified in 7.3.102.2 Table 101 and
ISO/DIS 21364-1:2019, 7.3.2, Table 4. If no top surface is provided, this surface is considered to extend
152 mm above the top edge of the compartment door(s).
During the test for pyrolytic ovens, the temperature rise of the surface of knobs and grips shall not
exceed the following values:
— metal   55 K
— porcelain or vitreous material  65 K
— moulded material, rubber or wood 80 K
The temperature rises of knobs and grips associated with functions that cannot be performed during
the cleaning operation are not determined.
7.3.102.4.2 Test
The manufacturer shall specify the temperature and duration of the self-cleaning mode.
Prior to conducting this test, the appliance shall be adjusted to obtain the self-cleaning temperature.
oSIST ISO/DIS 21364-22:2020
ISO/DIS 21364-22:2020(E)
This test shall be conducted according to 7.3.102 and ISO/DIS 21364-1:2019, 7.3.1 except that the oven(s)
temperature shall be the self-cleaning temperature.
If the appliance includes two compartments, a non-self-cleaning compartment shall remain inoperative
during the test. Two self-cleaning compartments shall be operated simultaneously, if the controls
permit such operation. If the controls do not permit simultaneous operation of the two self-cleaning
compartments, individual tests shall be conducted on each compartment.
The appliance shall be operated through the longest cleaning cycle attainable by using the control
system or until all contact temperatures of the exterior surfaces to be measured are constant,
whichever results in the shorter operating time. Points of expected maximum contact temperature
shall be monitored throughout the duration of the self-cleaning mode.
7.3.102.5 Temperatures of accidentally touchable surfaces of a portable table-top oven or
compartment grill
7.3.102.5.1 Requirement
During the following test, the temperature rise of surfaces shall not exceed the values specified in
Table 102.
7.3.102.5.2 Test
The portable table-top oven or compartment grill is placed as specified in ISO/DIS 21364-1:2019,
5.6.4 and is supplied with reference gas at normal pressure according to the corresponding Table of
ISO/DIS 21364-1:2019, Annex A.
The appliance is operated without accessories, with the exception of a grid with the thermocouple for
measuring the centre temperature of the compartment.
For an oven with a thermostat, the control is positioned in order to obtain an average temperature of
200 °C at the centre of the compartment.
For an oven without a thermostat, the control is set to the highest position until a temperature of about
200 °C is obtained at the centre of the compartment. The control is then set to the position allowing a
temperature of 200 °C to be maintained.
Ovens are operated until steady conditions are established or for 60 min, whichever is shorter.
The grill burner is operated for 30 min. A grill burner with means to reduce the heat input is operated
for 15 min with the control adjusted to full rate position and then for 15 min at a setting which reduces
it to half of the nominal heat input.
If for a compartment grill the instructions for use and maintenance state that for grilling the door
shall be closed, the test is performed with the controls set according to the instructions for use and
maintenance.
If the appliance is provided with a rotating spit, it is operated with the spit rotating for 60 min. The
controls are set to give the most unfavourable conditions specified in the instructions for use and
maintenance. The measurements are only carried out on surfaces for which temperature rise limits for
the front surface of the appliance door apply.
Temperature rises are not measured on the follow
