The work of preparing International Standards is normally carried out through ISO t

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates clos
32、ely 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 the ISO/IEC Directives, Part 1. In particular the different approval criteria n
33、eeded 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 possibility that some of the elements of this document may be the subject of paten

37、consists of the following parts, under the general title Cryogenic vessels Toughness requirements for materials at cryogenic temperature: Part 1: Temperatures below -80 C Part 2: Temperatures between -80 C and -20 CDIN EN ISO 21028-1:2017-01 EN ISO 21028-1:2016 (E)5 IntroductionThe use of materials
38、at low temperatures entails special problems which are to be addressed. Consideration is to be given, in particular, to changes in mechanical characteristics, expansion and contraction phenomena and the thermal conduction of the various materials. Austenitic stainless steel can transform from the au
39、stenitic to the martensitic phase when cooled down, leading to dimensional change that needs to be considered during design.However, the most important property to be considered is material toughness at low temperatures.DIN EN ISO 21028-1:2017-01 EN ISO 21028-1:2016 (E)6 1 ScopeThis part of ISO 2102
40、8 specifies the toughness requirements of metallic materials for use at a temperature below -80 C to ensure their suitability for cryogenic vessels.This part of ISO 21028 is not applicable to unalloyed steels and cast materials.2 Normative referencesThe following documents are referred to in the tex
