Scope: This document 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. This document also establishes general principles for the maintenance of cylinder bundles. This document is not applicable to acetylene bundles with solvent-free acetylene cylinders. This document 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.
