Domestic cooking appliances burning gas - Part 1-4: Safety- Appliances having one or more burners with an automatic burner control system
This European Standard specifies the construction and performance characteristics as well as the requirements and methods of test for the safety and marking of domestic cooking appliances, capable of using the combustible gases defined in EN 30-1-1:2008+A2:2010, that have one or more burners with an automatic burner control system, referred to in the text as "appliances".
This European Standard includes specific requirements and methods of test that are applicable to burners having an automatic burner control system, whether or not the appliance is equipped with a fan for the supply of combustion air to, and/or the evacuation of the products of combustion from the burner concerned. These specific requirements and methods of test are only applicable when the burner has an automatic burner control system and do not apply to burners having automatic ignition that fall within the scope of
EN 30-1-1:2008+A2:2010.
This European Standard is intended to be used in conjunction with EN 30-1-1:2008+A2:2010 and, where appropriate, other parts of EN 30-1 covering appliances having:
- forced-convection ovens and/or grills;
- a glass ceramic hotplate.
It does not cover all of the safety requirements and methods of test that are specific to forced-convection ovens and/or grills and glass ceramic hotplates.
Unless specifically excluded hereafter, this 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 of their associated equipment ).
This European Standard does not apply to:
- outdoor appliances;
- appliances connected to a combustion products evacuation duct;
- appliances having a pyrolytic gas oven;
- appliances having automatic burner control systems that:
- have a second safety time (see EN 298:2003), or
- control one or more burners that incorporate a separate ignition burner;
- appliances having an uncovered burner or a non-enclosed covered burner (see 3.1.1) that utilises a fan for the supply of its combustion air;
- appliances having enclosed covered burners that are not equipped with an automatic burner control system;
- appliances having one or more burners that are capable of remote operation (type1), unless the burner(s) concerned are:
- oven burners equipped with an automatic burner control system, or
- oven burners of time-controlled ovens that are designed for a delayed start without the user being present;
- appliances having one or more burners that are capable of remote operation (type 2), unless the burner(s) concerned are:
- oven, grill or hotplate burners equipped with automatic burner control systems, or
- oven burners of time-controlled ovens that are designed for a delayed start without the user being present;
- appliances supplied at pressures greater than those defined in 7.1.3;
- appliances equipped with air-gas ratio controls;
- appliances incorporating one or more hotplate or grill burners that enable the user to program the delayed start of a cooking cycle.
This European Standard does not cover the requirements relating to automatic on-off cycling multi-ring hotplate burners for which specific requirements are under consideration.
This European Standard does not cover the requirements relating to third family gas cylinders, their regulators and their connection.
This European Standard only covers type testing.

This document (prEN 30-1-4:2021) has been prepared by Technical Committee CEN/TC 49 “Gas
cooking appliances”, the secretariat of which is held by UNI.This document is currently submitted to the Enquiry.
This document will supersede EN 30-1-4:2012.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.It is intended to use this document with FprEN 30-1-1:2021, on which the requirements and methods of
test for appliances having one or more burners with an automatic burner control system are based. In
particular, this document identifies the requirements and methods of test specific to these appliances,
which are in addition to, or replace, those given in FprEN 30-1-1:2021.This present part is intended to be used together with any other part of EN 30-1-x related to “Safety”,
whenever the appliances covered by this other part includes a burner with an automatic burner control
system.Requirements relating to ‘Rational use of energy’ are given in other appropriate parts of this document,

1 Scope
This document specifies the construction and performance characteristics as well as the requirements
and methods of test for the safety and marking of domestic cooking appliances, capable of using the
combustible gases defined in FprEN 30-1-1:2021 that have one or more burners with an automatic
burner control system, referred to in the text as “appliances”.This document includes specific requirements and methods of test that are applicable to burners having
an automatic burner control system, whether or not the appliance is equipped with a fan for the supply
of combustion air to, and/or the evacuation of the products of combustion from the burner concerned.
These specific requirements and methods of test are only applicable when the burner has an automatic
burner control system and do not apply to burners having automatic ignition that fall within the scope
of FprEN 30-1-1:2021.This document is intended to be used in conjunction with FprEN 30-1-1:2021 and, where appropriate,
other parts of EN 30-1 covering appliances having:— forced-convection ovens and/or grills;
— a glass ceramic hob.
This document does not cover all of the safety requirements and methods of test that are specific to
forced-convection ovens and/or grills and glass ceramic hobs.Unless specifically excluded hereafter, this document 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 document 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 of their associated equipment .This document does not apply to:
