ISO 20475:2018
Gas cylinders — Cylinder bundles — Periodic inspection and testing
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.
