32、)4 IntroductionElements of this document support the requirements of the UN-Recommendations on the Transport of Dangerous Goods and other international, national or local requirements.Large transportable cryogenic vessels are often partly equipped by the manufacturer, but may be completed or re-equi

33、pped by another party, such as the operator or owner. For this reason, some of the scope of this document, which includes putting into service, inspection, filling, maintenance and emergency procedures, overlaps with ISO 20421-1.This document applies to vessels for cryogenic fluids, primarily as spe

34、cified in ISO 20421-1. It may also be used for vessels for cryogenic fluids manufactured and designed to other standards, e.g. EN 13530-2. In case of conflict between the requirements of this document with applicable regulations, regulations take precedence.DIN EN ISO 20421-2:2017-05 EN ISO 20421-2:

35、2017 (E)5 1 ScopeThis document specifies operational requirements for large transportable vacuum-insulated cryogenic vessels.These operational requirements include putting into service, filling, withdrawal, transport within the location, storage, maintenance, periodic inspection and emergency proced

36、ures.For the transport of these vessels by public road, rail, waterway, sea and air, additional requirements can apply; these are defined in specific regulations.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requ
