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.
This standard is applicable 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 13,2 bar.
However, stenching of these gases is optional for cartridges with a total capacity not exceeding 150 ml.
This standard is not applicable to aerosol dispensers — manufactured, filled, tested and marked in accordance with the Directive 75/324/EEC.
