31、 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 safety at any stage. It has

32、 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. All pressures are gauge unl

DIN EN 14427:2014-09 EN 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 0,5 litre up to and i

35、ncluding 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 material (welded or seamles

36、s) 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 European Standard do

37、es 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 referenced in this document
