CAUTION — Some of the tests specified in this document involve the use of processes (e.g. pneumatic pressurization) which could lead to a hazardous situation.

This document describes the use of modal acoustic emission (MAE) testing during periodic inspection and testing of hoop wrapped and fully wrapped composite transportable gas cylinders and tubes, with aluminium-alloy, steel or non-metallic liners or of linerless construction, intended for compressed and liquefied gases under pressure.

This document addresses the periodic inspection and testing of composite cylinders constructed to ISO 11119-1, ISO 11119-2, ISO 11119-3, ISO 11515 and ISO/TS 17519 and can be applied to other composite cylinders designed to comparable standards when authorized by the competent authority.

Unless noted by exception, the use of "cylinder" in this document refers to both cylinders and tubes.Cross References:ASTM E1106-12ISO 11623ISO 9712ASTM E587-10ISO 10286ISO 11119-2ISO 7225EN 14584ISO 11119-3ASNT SNT-TC-1AISO 22434ISO/TR 11364ISO 11119-1ASTM E1419-09 ISO 16148ASTM E2223-13ISO 11114-2ASTM E543-13ISO 25760ISO 12716ISO 11515CGA C-18ISO/TS 17519ISO 12714ISO 12713ISO 11621
