30、O 11623:2015ISO 11623:2015(E)IntroductionThe principal aim of periodic inspection and testing is that at the completion of the test, the cylinders can be reintroduced into service for a further period of time. It is not possible to identify all considerations for periodic inspection and testing of c
31、omposite cylinders in this International Standard. In such cases or where there is doubt, questions regarding specific cylinders should be directed to the manufacturer or owner.This International Standard is intended to be used under a variety of national regulatory regimes, but has been written so
32、that it is suitable for the application of the UN Model Regulations (see Reference 1). Attention is drawn to requirements in the relevant national regulations of the country (countries) where the cylinders are intended to be used that might override the requirements given in this International Stand
33、ard. Where there is any conflict between this International Standard and any applicable regulation, the regulation always takes precedence. ISO 2015 All rights reserved vBS EN ISO 11623:2015BS EN ISO 11623:2015Gas cylinders Composite construction Periodic inspection and testing1 ScopeThis Internatio
34、nal Standard specifies the requirements for periodic inspection and testing and to verify the integrity for further service of hoop-wrapped and fully-wrapped composite transportable gas cylinders, with aluminium-alloy, steel or non-metallic liners or of linerless construction (Types 2, 3, 4, and 5),
35、 intended for compressed, liquefied or dissolved gases under pressure, of water capacity from 0,5 l up to 450 l.This International Standard is written to address the periodic inspection and testing of composite cylinders constructed to ISO 11119-1, ISO 11119-2, and ISO 11119-3 standards and can be a
36、pplied to other composite cylinders designed to comparable standards when authorized by the competent authority.As far as practicable, this International Standard also can be applied to cylinders of less than 0,5 l water capacity.2 Normative referencesThe following documents, in whole or in part, ar
