The specific
21、ations given are based on knowledge of, and experience with, materials, design requirements, manufacturing processes and control during manufacture of cylinders in common use in the countries of the CEN members.

22、SI BS EN 12245:2009 EN 12245:2009 (E) 5 1 Scope This European Standard specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of composite gas cylinders for compressed, liquefied and dissolved gases. NOTE 1 For the purposes of
23、this European Standard, the word “cylinder” includes tubes (seamless transportable pressure receptacles of a water capacity exceeding 150 litres and of not more than 3 000 litres). This European Standard is applicable to cylinders that comprise a liner of metallic material (welded or seamless) or no
24、n-metallic material (or a mixture thereof), reinforced by a wound composite consisting of fibres of glass, carbon or aramid (or a mixture thereof) embedded in a matrix. This European Standard is also applicable to composite cylinders without liners. This European Standard is not applicable to gas cy
25、linders which are partially covered with fibres and commonly called “hoop wrapped“ cylinders. For hoop wrapped composite cylinders, see EN 12257. NOTE 2 This European Standard does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, they should be
26、 considered separately. This European Standard is primarily for industrial gases other than LPG but may also be applied to LPG. NOTE 3 For dedicated LPG cylinders, see EN 14427. 2 Normative references The following referenced documents are indispensable for the application of this document. For date
27、d references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
