27、4427:2014EN 14427:2014 (E) 5 Introduction This European Standard calls for the use of substances and procedures that can be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and s
28、afety at any stage. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. It is recommended that manufacturers develop an environmental management policy. For guidance see ISO 14000 series. A
29、ll pressures are gauge unless otherwise stated. NOTE This standard requires measurement of material properties, dimensions and pressures. All such measurements are subject to a degree of uncertainty due to tolerances in measuring equipment, etc. It may be beneficial to refer to the leaflet “Measurem
30、ent uncertainty leaflet SP INFO 2000 27” 14. BS EN 14427:2014EN 14427:2014 (E) 6 1 Scope This European Standard specifies minimum requirements for materials, design, construction, prototype testing and routine manufacturing inspections of fully wrapped composite cylinders with a water capacity from
31、0,5 litre up to and including 150 litres for liquefied petroleum gases (LPG) exposed to ambient temperatures, with a test pressure of at least 30 bar; is only applicable to cylinders which are fitted with a pressure relief valve (see 4.1.3); is applicable to cylinders with a liner of metallic materi
32、al (welded or seamless) or non-metallic material (or a mixture thereof), reinforced by fibres of glass, carbon or aramid (or a mixture thereof); is also applicable to composite cylinders without liners. Cylinders manufactured to this European Standard are suitable for temperatures down to 40 C. This
33、 European Standard does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, the choice of material and sleeve performance should be considered separately. 2 Normative references The following documents, in whole or in part, are normatively referen
