SIST EN 417:2012
EN 417:2012 (E) 4 Introduction This standard covers “non-refillable metallic cartridges for liquefied petroleum gases, with or without a valve, for use with portable appliances”. It has become necessary to establish a specific standard for these cartridges, as the European Directive 2008/47/EC [2] 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 describes a procedure which can serve as a guide to the person in the organisation who is responsible for issuing type examination certificates. The cartridges covered by this standard may fall under the scope of various directives, which are listed in the bibliography. SIST EN 417:2012
EN 417:2012 (E) 5 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. This European 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 and/or di-methyl-ether or equivalent, 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 European Standard is not applicable for aerosol dispensers — manufactured, filled, tested and marked in accordance with Directive 2008/47/EEC. This European Standard does not apply to appliances with an integral gas container which is not interchangeable, or to cartridges for filling such containers (e.g. lighters). 2 Normative references EN 521, Specifications for dedicated liquefied petroleum gas appliances — Portable vapour pressure liquefied petroleum gas appliances 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 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 3.2 pierceable gas cartridge cartridge without a valve NOTE 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. 3.3 two pieces gas cartridge with valve cartridge constructed of two pieces with an aperture at the top end into which a male or female valve is fitted NOTE The gas supply is obtained by the connection of the portable appliance to the valve. 3.4 three pieces gas cartridge with valve cartridge constructed of three pieces with an aperture at the top end into which a male or female valve is fitted NOTE The gas supply is obtained by the connection of a portable appliance to the valve.

No bubbles shall be observed coming from the cartridge over a period of 3 min; when the test at –20 °C has been carried out, the cartridge is immersed in a liquid at 0 °C for 1 h. No bubbles shall be seen coming from the cartridge over a further period of 3 min; SIST EN 417:2012
EN 417:2012 (E) 15 the cartridge is then left at an ambient temperature of about 20 °C for 1 h, then placed in a container of water. The assembly is brought to a temperature of 70 °C in a time not less than 30 min. No bubbles shall then be observed coming from the cartridge over a further period of 3 min. 6.6 Gas tightness of valves This test is performed on five samples: the valve is subjected to 50 opening and closing operations at (20 ± 5) °C using the adaptor of an appliance designed for use with the cartridge; each operation consists of fully fitting and fully removing the adaptor from the cartridge; after these operations the cartridge is placed in a water bath at a temperature of (50 50+) °C for 15 min. No bubbles shall be seen coming from the cartridge over a further period of 3 min. 6.7 Drop test The test is carried out on 15 samples. If cartridges are marketed with a protective cover fitted to the valve, the tests are carried out with the protective cover fitted. The test is performed by dropping the cartridge from a height of 1,2 m onto a hard surface (concrete, thick steel plate, etc.); new cartridges shall be used for each test: five cartridges shall be dropped on the top; five cartridges shall be dropped on the base; five cartridges shall be dropped on the side. After the test, carried out at an ambient temperature of (20 ± 5) °C, the cartridges are plunged into a water bath at (20 ± 5) °C. No signs of leakage shall be apparent for a period of 3 min. If any of the cartridges fail the test, the test which caused the failure shall be repeated on five new cartridges. If after the re-test there are no failures, the result of the test is judged to be satisfactory. 6.8 Threaded centre boss valve – Mechanical strength torque test The test is performed on five valves, using the test adaptor and clamping device specified in Figure 5. Each valve is fitted into the clamping device which is tightened to prevent rotation of the valve. The test adaptor is screwed onto the valve and tightened to a torque of 15 N⋅m at a rate of approximately 1 N⋅m/s. The valve shall not break. SIST EN 417:2012
