It has become necessary to establish a specific standard for these cartridges, as the European Directive 75/324/EEC concerning aerosol generators does not cover the essential functions of cartridges for liquefied petroleum gas, i.e. containing a gas suitable for the operation of the appliance and supplying the appliance in a gas tight fashion, taking account of its geometry and the heating that might occur. The safety of the user therefore depends on the use of cartridges complying with this standard, which in consequence, will be marked, inspected and tested in accordance with the requirements of this standard. This standard also defines the tests to be used as a basis for type examination and pending a European Directive for these cartridges, describes a procedure which can serve as a guide to the organizations responsible for issuing type examination certificates. This standard does not apply to appliances with an integral gas container which is not interchangeable, or to cartridges for filling such containers. 1 Scope This European Standard specifies material, construction, inspection and marking requirements for non-refillable metallic gas cartridges with or without a valve for use with portable appliances which comply with the requirements of EN 521 “Portable appliances operating at vapour pressure from liquefied petroleum gas containers”.1) This standard applies to cartridges with a total capacity of between 50 ml and 1 000 ml, designed to contain stenched liquefied petroleum gas or stabilized mixtures of liquefied petroleum gas with propadiene and/or methyl acetylene, where the pressure developed by the contents of the cartridge at 50 °C does not exceed 12 bar. However, stenching of these gases is optional for cartridges with a total capacity not exceeding 150 ml. This standard does not apply to aerosol dispensers manufactured, filled, tested and marked in accordance with the Directive 75/324/EEC. 2 Definitions For the purposes of this standard, the following definitions apply. 2.1 gas cartridge non-refillable container filled once only with gas or a mixture of gases for fuelling portable gas appliances which burn the gas or gases in use 2.2 pierceable gas cartridge a cartridge without a valve. The gas supply is obtained by piercing the cartridge by means of a specific device which is part of the portable appliance with which the cartridge is to be used 2.3 two piece gas cartridge with valve a cartridge constructed of two pieces with an aperture at the top end into which a male or female valve is fitted. The gas supply is obtained by the connection of the portable appliance to the valve 2.4 three piece gas cartridge with valve a cartridge constructed of three pieces with an aperture at the top end into which a male or female valve is fitted. The gas supply is obtained by the connection of a portable appliance to the valve 2.5 total capacity the internal volume of the empty gas cartridge at 20 °C, expressed in millilitres, before any accessories are fitted, such as valves, etc. 2.6 net capacity the volume, expressed in millilitres, which is available to receive the contents when the gas cartridge is sealed and fitted with its accessories 2.7 test pressure pressure that is equal at a temperature of 50 °C to 1,5 times the pressure which would be developed by gas with which the cartridge will be filled, or 10 bar, whichever is the greater 2.8 burst pressure the minimum pressure which causes leakage from the gas cartridge 1) In preparation at the time of the publication of this standard. PrEN 521 has been submitted to six months enquiry until 1991-12-27.

Gas cartridges designed to contain mixtures of liquefied petroleum gas and methylacetylene shall not be manufactured from materials containing more than 70 % copper. 3.2 Design and construction General 3.2.1 Gas cartridges shall be constructed from one or more parts, these being assembled by welding, brazing, crimping, etc. 3.2.2 Gas cartridges with an outside diameter exceeding 40 mm shall be provided with a concave base. 3.2.3 Gas cartridges shall be so designed and constructed that they do not leak or show visible permanent deformation when subjected to an internal pressure equal to the test pressure. 3.2.4 Gas cartridges shall be so designed and constructed that they do not leak or rupture when subjected to an internal pressure equal to 1,2 times the test pressure. 3.2.5 The concave form of the base of gas cartridges with an outside diameter exceeding 40 mm shall reverse in form before any leak appears or rupture occurs. However, for three piece construction cartridges with valves, with an outside diameter exceeding 40 mm, either the concave form of the base shall reverse or the domed top shall permanently extend before any leak appears or any rupture occurs. 3.2.6 Gas cartridges shall be so designed and constructed that they do not leak at temperatures from 20 °C to + 70 °C. 3.2.7 The dimensions of the cartridge shall be such as to ensure that it is compatible with the appliance
