This document specifies stamp marking requirements for transportable refillable LPG cylinders and metallic drums including:

— Steel LPG cylinders designed and manufactured in accordance with EN 1442, EN 14140, EN 12807 or an equivalent standard or technical code recognized by the Competent Authority.

— LPG metallic drums designed and manufactured in accordance with EN 14893 or an equivalent standard or technical code recognized by the Competent Authority.

— Welded aluminium LPG cylinders designed and manufactured in accordance with EN 13110 or an equivalent standard or technical code recognized by the Competent Authority.

— LPG composite cylinders designed and manufactured in accordance with EN 14427 or an equivalent standard or technical code recognized by the Competent Authority.

NOTE 1 All these types of receptacles are referred to throughout this document as "cylinders".

This document does not specify any requirements for product, hazard or safety-phrase labelling of packaging which may be required to meet ADR or other legislative requirements.

NOTE 2 The marking of cylinders is regulated by RID/ADR which take precedence over any clause in this document. The European Directive on Transportable Pressure Equipment 2010/35/EU [8] includes additional marking requirements (π -marking).

This document specifies the minimum requirements for the protection of helium cryostats against excessive pressure, including the specific risks associated with cryostats for superconducting magnets and cryostats for superconducting radio-frequency cavities, coldboxes of helium refrigerators and liquefiers as well as helium distribution systems including valve boxes. It includes risk assessment, protection concepts, dimensioning of pressure relief devices, types of pressure relief devices, substance release and operation of helium cryostats.

In order to fulfil the aim of this document, the characteristics of pressure relief devices are taken into account.

ISO 20475:2018 specifies the requirements for the periodic inspection and testing of cylinder bundles containing compressed, liquefied and dissolved gas. NOTE Additional requirements for acetylene cylinder bundles are provided in Annex A. ISO 20475:2018 also establishes general principles for the maintenance of cylinder bundles. ISO 20475:2018 is not applicable to acetylene bundles with solvent-free acetylene cylinders. ISO 20475:2018 excludes the requirements for cylinder bundles when they are a part of a battery vehicle. For some specific applications, e.g. offshore, additional requirements can apply.
