27、1:2011 (E) 5 Introduction The purpose of this European Standard is to provide a specification for the design, manufacture, inspection and testing of refillable, transportable fully wrapped composite cylinders. The specifications given are based on knowledge of, and experience with, materials, design
28、 requirements, manufacturing processes and control during manufacture of cylinders in common use in the countries of the CEN members. BS EN 12245:2009+A1:2011EN 12245:2009+A1:2011 (E) 6 1 Scope This European Standard specifies minimum requirements for the materials, design, construction, prototype t
29、esting and routine manufacturing inspections of composite gas cylinders for compressed, liquefied and dissolved gases. NOTE 1 For the purposes of this European Standard, the word “cylinder” includes tubes (seamless transportable pressure receptacles of a water capacity exceeding 150 litres and of no
30、t more than 3 000 litres). This European Standard is applicable to cylinders that comprise a liner of metallic material (welded or seamless) or non-metallic material (or a mixture thereof), reinforced by a wound composite consisting of fibres of glass, carbon or aramid (or a mixture thereof) embedde
31、d in a matrix. This European Standard is also applicable to composite cylinders without liners. This European Standard is not applicable to gas cylinders which are partially covered with fibres and commonly called “hoop wrapped“ cylinders. For hoop wrapped composite cylinders, see EN 12257. NOTE 2 T
32、his European Standard does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, they should be 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 c
