This European Standard 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 container. It also defines test methods and the requirements for marking and the information to be given in the instructions.
NOTE   These appliances are referred to in the body of the text as "appliances".
This European Standard applies to various types of portable appliances burning liquefied petroleum gases at vapour pressure and designed to be used with (non refillable) cartridges as complying with EN 417 or any types of gas cylinders other than cartridges. For example the following types of appliances are covered:
a)   cooking appliances (hotplates, grills, barbecues...).
This European Standard does not cover barbecues that can be used indoors;
b)   lighting appliances;
c)   heating appliances.
This European Standard only applies to appliances with a maximum heat input of up to 3 kW (Hs) for outdoor use only;
d)   blowlamps.
This European Standard only applies to blowlamps without a flexible hose;
e)   laboratory burners.
The requirements apply to these appliances or their functional sections whether or not the latter are independent or incorporated into an assembly.
This European Standard only applies to type examination.
Appliances covered by this European Standard are not connected to a flue for the discharge of products of combustion and are not connected to the mains electricity supply.
This European Standard covers neither appliances supplied with LPG in the liquid phase nor those incorporating a fixed gas reservoir which may or may not be refilled by the user. This European Standard does not cover gas containers or flexible hose.

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.

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 defines the qualification test of welders for the fusion welding of steels.
It provides a set of technical rules for a systematic qualification test of the welder, and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner/examining body.
When qualifying welders, the emphasis is placed on the welders ability to manually manipulate the electrode/ welding torch/ welding blowpipe and thereby producing a weld of acceptable quality.
The welding processes referred to in this European Standard include those fusion welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automated welding processes (see EN 1418).
