The
21、 work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-gove
22、rnmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in
23、 the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the po
24、ssibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list

30、-2:2015BS EN ISO 21029-2:2015Cryogenic vessels Transportable vacuum insulated vessels of not more than 1 000 litres volume Part 2: Operational requirements1 ScopeThis part of ISO 21029 specifies operational requirements for transportable vacuum insulated cryogenic vessels of not more than 1 000 l vo
31、lume designed to operate above atmospheric pressure. Appropriate parts may be used as a guidance for a vessel design to operate open to the atmosphere.For cryogenic vessels designed for personal medical use, other requirements can apply.The scope includes putting into service, filling, withdrawal, t
32、ransport within the location, storage, maintenance, periodic inspection, and emergency procedures.For the transportation of these vessels by public road, rail, sea, and air, other additional requirements can apply; these are defined in specific regulations.Transportable cryogenic vessels of not more
33、 than 1 000 l volume are often partly equipped by the manufacturer, but can be installed or re-installed by another party, such as the operator or owner. For this reason, some of the scope of this part of ISO 21029, which includes putting into service, inspection, filling, maintenance, and emergency
34、 procedure, overlaps with ISO 21029-1.2 Normative referencesThe following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition
35、 of the referenced document (including any amendments) applies.ISO 21010, Cryogenic vessels Gas/materials compatibilityISO 23208, Cryogenic vessels Cleanliness for cryogenic service3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.3.1putting into ser

44、port regulations;d) risk and safety phrases associated with the gas content;e) name and address of the fluid producer or supplier.All vessels shall include a product identification label visible from all directions (e.g. 360 wrap-around tape), which can be easily read from a distance of 2 m, and sec
45、urely affixed product labels at the inlet and outlet connections. Additionally, warning labels reading, “Never use adapters or try to change gas connections on the vessel when trying to attach a product distribution connection” shall be affixed at outlet connections.4.3 Handover documentsIn addition
46、 to the manufacturers documentation where necessary, the cryogenic vessel shall be accompanied by vessel specific documents and instructions for all the following items: operations; auxiliary equipment; inspection records.These documents shall be retained by the owner of the vessel.The operator shal
47、l have appropriate instructions available. Such instructions may be attached to the vessel in a permanent manner.5 Personnel trainingOnly persons trained for the specific task shall be allowed to put into service, fill, handle, operate, or maintain the vessel and its accessories.The training program
48、me shall include the following: normal procedures; product and hazard identification; safe operating limits; emergency procedures; physical and chemical properties of the vessels contents and their effects on the human body; personnel protective equipment (e.g. safety boots/goggles/gloves).Training
49、shall be repeated as necessary to ensure that personnel remain competent.
