This standard specifies the constructional and performance characteristics, safety specifications and rational use of energy, relevant test methods and marking of burners burning liquefied petroleum gas and designed to heat up vessels of diameter greater than 300 mm, containing liquids or food. This standard overs appliances, generally floor standing, fitted with one or several open burners without enclosure, designed to be used outdoors and operating with the gases corresponding to the categories indicated in 4.

This document specifies constructional and performance characteristics, safety specifications and rational use of energy, relevant test methods and marking of independent stoves, side burners, covered burners, open burners, griddles, radiant grills, burning liquefied petroleum gas, referred to in the body of the text as "appliances".
This document covers appliances, used outdoors and operating with the gases of the third family according to EN 437:2018.
Appliances used in leisure vehicles and boats are outside the field of application of this standard.
Independent stove burners, whose nominal heat input is below 1,16 kW, griddles and radiant grills, are not subject to any special requirement concerning the rational use of energy due to their low rate and their use for short periods of time.
This document does not state all requirements for appliances of other nature incorporating a stove (for example barbecues are not covered by this standard but a side burner of a barbecue is covered by this standard).
This document does not cover regulators that are used with those appliances.

This document specifies the construction and performance characteristics related to safety and the rational use of energy of portable appliances burning liquefied petroleum gases at the vapour pressure within the gas cartridge or gas cylinder, excepting those where the gas cartridge is inserted horizontally in the chassis.

This document applies to various types of portable appliances burning liquefied petroleum gases at vapour pressure and designed to be used with cartridges as complying with EN 417 or gas cylinders.
This document covers appliances for outdoor or in well ventilated areas uses only.
For example the following types of appliances are covered:
a)   cooking appliances (stoves, grills, barbecues...);
This document does not cover barbecues that can be used indoors;
b)   lighting appliances;
c)   heating appliances;
This document only applies to appliances with a maximum heat input of up to 3 kW (Hs) for outdoor use only;

It does not apply to gas appliances operating with a valve cartridge which is horizontally integrated into the chassis of the appliance also called "flat portable gas stove".
Requirements for rational use of energy have been included for stove burners.
However, such requirements have not been included for the other types of appliances because:
-   for grills and barbecues, this is a type of cooking which is achieved by various means such as radiant elements; in addition this type of cooking varies according to the type of food and region where the appliance is used;
-   for lighting appliances, the consumption is insignificant because these appliances have a very low rate and are used only for a few hours in a year;
-   for heating appliances, all the heat produced is discharged into the environment;
-   for tools such as blowtorches which are not professional tools in regular use, the gas consumption depends very much on the way it is used.

This European Standard applies to these appliances and their functional sections whether or not the latter are independent or incorporated into an assembly.
This European Standard also applies to appliances designed to be built-in.
This European Standard only applies to type testing.
Appliances supplied with third family gas at pressures greater those defined in 4.2 are outside the field of application of this European Standard.
During the consideration of this text, it was apparent that the concept of thermal efficiency with regard to appliances such as barbecues was not appropriate.
This is because:
-   during cooking, there is an additional transfer of heat due to the meat juices falling onto the refractories;
-   there is no relation between the item to be cooked and the useful area;
-   the barbecue is an outdoor appliance in which the action of the wind is important in relation to efficiency.
In consequence there is no specific requirement covering thermal efficiency for this type of appliance.
This European Standard does not state all applicable requirements for integral equipments of other nature (for example burners covered by EN 484).
