BS EN 417:2012EN 417:2012 (E) 4 Introduction This standard covers “non-refillable metallic cartridges for liquefied petroleum gases, with or without a valve, for use with p

20、ortable 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

21、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 accordan

22、ce 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 th

23、is standard may fall under the scope of various directives, which are listed in the bibliography. BS EN 417:2012EN 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 fo

24、r 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

25、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 applica

26、ble 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 refe

28、 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 t

29、he 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

30、 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. BS EN 417:2012EN 417:2012 (E) 6 3.5 total capacity internal volume of the empty gas ca

31、rtridge at 20 C before any accessories are fitted NOTE 1 Accessories are such as valves, etc. NOTE 2 The total capacity is expressed in millilitres. 3.6 net capacity volume, expressed in millilitres, which is available to receive the contents when the gas cartridge is sealed and fitted with its acce

32、ssories 3.7 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 3.8 burst pressure minimum pressure which causes leakage from the gas cartridge 3.9 volume

34、of propane, propene, butane, butane isomers, butene with traces of other hydrocarbon gases 3.11 stenched liquefied petroleum gas liquefied petroleum gas with the addition of an odorant detectable in the gas/air mix 3.12 female valve valve designed so that the spigot fitting of an appropriate applian

36、w when the cartridge is pierced and not fitted to the gas appliance 4 Materials, design and construction 4.1 Materials 4.1.1 The body of the gas cartridge and the valve cup where applicable, with the exception of the sealing material, shall be made of metal. BS EN 417:2012EN 417:2012 (E) 7 For the b

37、ody of the cartridges the composition and the mechanical characteristics of the metal shall be detailed in a document provided by the material manufacturer. 4.1.2 The materials used for the container, the valve, any internal lining, external coatings, internal leakage limiter and seals shall be comp

38、atible with the gases to be contained by the cartridge and shall withstand the reasonably foreseeable mechanical, thermal and chemical conditions which may occur during use and storage. Gas cartridges designed to contain mixtures of liquefied petroleum gas and methylacetylene shall not be manufactur

39、ed from materials containing more than 70 % copper. 4.2 Design and construction General 4.2.1 Gas cartridges shall be constructed from one or more parts, these being assembled by welding, brazing, crimping, etc. 4.2.2 Gas cartridges with an outside diameter of 40 mm and above shall be provided with

40、a concave base. 4.2.3 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. 4.2.4 Gas cartridges shall be so designed and constructed that they do not leak or burst until a pr

41、essure 1,2 times the test pressure has been reached or passed. 4.2.5 The concave form of the base of gas cartridges with an outside diameter greater than or equal to 40 mm shall reverse in form before any leak appears or rupture occurs. However, for three pieces construction cartridges with valves,

42、with an outside diameter greater than or equal to 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. 4.2.6 Gas cartridges shall be so designed and constructed that they do not leak at temperatures from 20

43、C to + 70 C. 4.2.7 The dimensions of the cartridge shall be such so as to ensure that it is compatible with the appliances designated on the cartridge (see 8.2). 4.2.8 The internal leakage limiter shall not disturb the correct operation of the cartridge and/or the appliance. 4.3 Pierceable cartridge

44、s 4.3.1 General Pierceable cartridges shall not be fitted with valve cups. Pierceable cartridges shall be fitted with an internal leakage limiter (an example of design is shown for information in Figure 6). 4.3.2 Type 200 cartridges For type 200 cartridges, (inside diameter 86 mm, containing approxi

45、mately 190 g of gas), the dimensions in Figure 1 shall be maintained. BS EN 417:2012EN 417:2012 (E) 8 Dimensions in millimetres Figure 1 Cartridge type 200 Across the whole height of the hatched area (except for the rounded edges top and bottom), the diameter shall be: a) (86,6 0,4) mm; or b) (82 0,

46、5) mm; or c) the design shall be such that the diameter alternates between the dimensions in a) and b) above. NOTE In this area, each cartridge manufacturer should choose the shape that is best suited to ensure the safety of the connection of the cartridge to the appliance, according to the characte

47、ristics of the appliances likely to be fuelled by his cartridges. BS EN 417:2012EN 417:2012 (E) 9 4.3.3 Other pierceable type cartridges Other capacities, dimensions and shapes of pierceable cartridges are permitted, provided that they cannot be fitted into and pierced by appliances designed for typ

48、e 200 cartridges. 4.4 Cartridges with valves 4.4.1 General requirements for every type of valve Cartridges with valves shall be designed in such a way that it is not possible to operate the valve without the use of a special adaptor unless an adequate protection against inadvertent discharge is prov

49、ided with and fitted on the cartridge. NOTE The connection on the appliance with which the gas cartridge is designed to be used may be considered as a special adaptor. The valves shall be of such a design that, under conditions of normal use, they close when the special adaptor is removed or the valve released. Valves which close by means of internal gas pressure only are not permitted. After 50 opening and closing operations, the valve shall not show signs of leakage or other defects (see 6.
