Domestic cooking appliances burning gas - Part 1-1: Safety - General
This European Standard specifies the construction and or characteristics as well as the requirements and methods of test for the safety and marking of freestanding and built-in domestic cooking appliances burning the combustible gases given in 4.1 according to the categories specified in 4.2, referred to in the text as "appliances".
The appliances covered by this standard are intended to be used by non-expert users in a domestic dwelling.
This European Standard covers the following types of domestic cooking appliances, as defined in Clause 3, and belonging to the classes defined in 4.3 (see Table 1):
- independent freestanding hobs;
- independent built-in hobs;
- hobs and grills;
- table cookers;
- freestanding ovens;
- built-in ovens;
- freestanding or built-in grills;
- griddles;
- freestanding cookers;
- built-in cookers.
Unless specifically excluded hereafter, this European Standard applies to these appliances or their component parts, whether or not the component parts are independent or incorporated into a single appliance, even if the other heating components of the appliance use electrical energy (e.g. combined gas-electric cookers).
This European Standard includes requirements covering the electrical safety of equipment incorporated in the appliance that is associated with the use of gas. It does not include requirements covering the electrical safety of electrically-heated component parts or their associated equipment.
For appliances intended to be used in caravans, or motorhomes/mobile homes or on board of ships or aircraft, additional requirements may be necessary.
This European Standard does not apply to:
a) outdoor appliances;
b) appliances connected to a combustion products evacuation duct;
c) appliances having a pyrolytic gas oven;
d) appliances having covered burners which do not comply with the constructional requirements of 5.2.8.2.2;
e) appliances incorporating flame supervision devices and having an automatic ignition device for which the duration of the ignition attempt is limited by design;
f) appliances equipped with a burner that is periodically ignited and extinguished under the control of an automatic on/off device;
g) appliances equipped with an oven and/or with a grill having a fan:
1) either for the supply of combustion air or for the evacuation of the products of combustion;
2) or for the circulation of the products of combustion within the compartments;
h) appliances supplied at pressures greater than those defined in 7.1.2;
i) appliances incorporating one or more hob or grill burners that enable the user to program the delayed start of the cooking cycle;
j) appliances of categories I2N, I2R, I3R, I2E(S), I2E(R), I2Esi, I2Er, I2R and the equivalent double and triple categories which include these indices;
k) appliances of category II2E+3B.
This European Standard does not cover the requirements relating to third family gas cylinders, their pressure regulators and their connection.

134 This document (prEN 30-1-1:2017) has been prepared by Technical Committee CEN/TC 49 “Gas
135 cooking appliances”, the secretariat of which is held by UNI.136 This document is currently submitted to the CEN Enquiry.
137 This document will supersede EN 30-1-1:2008+A3:2013.
138 This document has been prepared under a mandate given to CEN by the European Commission and the
139 European Free Trade Association, and supports essential requirements of EU Directive(s).
140 For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
141 document.142 The main modification in this standard with reference to the previous edition
143 (EN 30-1-1:2008+A3:2013) are the following:144 — Alignment with Regulation 2016/426/EU throughout the full text;
145 — Reference to the different types of gases is now given by making reference to the specific
146 EN 437:2003+A1:2009 and not by introducing its requirements in this Standard (various clauses
147 and Annex A);148 — Reference to specific requirements for multifunctional controls is now given by making reference to
149 the specific EN 126:2012 (5.2.14);150 — Addition of requirements for appliances that enable the user to program the end of a cooking cycle
151 (5.2.13);152 — Removal of requirements for ovens volume calculation as reference is made to EN 15181:2017;
153 — Removal of requirements for pilot flames as they are no more used on appliances (7.3.1.3.2);
154 — Introduction of requirements on accuracy of instruments (7.4);155 — More detailed info on types of inlets allowed for the connection of the appliances (5.2.6 and A.7).
156 EN 30 consists of the following parts:157 — prEN 30-1-1, Domestic cooking appliances burning gas — Part 1-1: Safety - General;

173 and methods of test for the safety and marking of freestanding and built-in domestic cooking appliances
174 burning the combustible gases given in 4.1 according to the categories specified in 4.2, referred to in the
175 text as “appliances”.176 The appliances covered by this standard are intended to be used by non-expert users in a domestic
177 dwelling.178 This European Standard covers the following types of domestic cooking appliances, as defined in
179 Clause 3, and belonging to the classes defined in 4.3 (see Table 1):180 — independent freestanding hobs;
181 — independent built-in hobs;
182 — hobs and grills;
183 — table cookers;
184 — freestanding ovens;
185 — built-in ovens;
186 — freestanding or built-in grills;
187 — griddles;
188 — freestanding cookers;
189 — built-in cookers.
190 Unless specifically excluded hereafter, this European Standard applies to these appliances or their
191 component parts, whether or not the component parts are independent or incorporated into a single
192 appliance, even if the other heating components of the appliance use electrical energy (e.g. combined
193 gas-electric cookers).194 This European Standard includes requirements covering the electrical safety of equipment
195 incorporated in the appliance that is associated with the use of gas. It does not include requirements
196 covering the electrical safety of electrically-heated component parts or their associated equipment .
197 For appliances intended to be used in caravans, or motorhomes/mobile homes or on board of ships or
198 aircraft, additional requirements may be necessary.199 This European Standard does not apply to:
200 a) outdoor appliances;
201 b) appliances connected to a combustion products evacuation duct;
202 c) appliances having a pyrolytic gas oven;
203 d) appliances having covered burners which do not comply with the constructional requirements of
204 5.2.8.2.2;1) See the electrical safety rules.
