This document 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 including 150 litres for liquefied petroleum gases (LPG) exposed to ambient temperatures, with a test pressure of at least 30 bar; \u2014 is only applicable to cylinders which are fitted with a pressure relief valve (see 4.1.3); \u2014 is applicable to cylinders with a liner of metallic material (welded or seamless) or non-metallic material (or a mixture thereof), reinforced by fibres of glass, carbon or aramid (or a mixture thereof); \u2014 is also applicable to composite cylinders without liners. Cylinders manufactured to this document are suitable for temperatures down to \u221240 \u00b0C. This document does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, the choice of material and sleeve performance are expected to be considered separately.<\/p>\n
