The work of preparing In

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-governmental, in liaison

27、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 the ISO/IEC Directiv

28、es, 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 possibility that some o

33、d. This test is designed to give an indication of how cryogenic spillage protection materials will perform in a sudden exposure to cryogenic liquid.The dimensions of the test specimen can be smaller than typical items of structure and plant and the release of liquid can be substantially less than th

34、at which might occur in a credible event. However, individual thermal and mechanical loads imparted to the cryogenic spillage protection materials, from the cryogenic spillage defined in the procedure described in this document, have been shown to be similar to those by large-scale cryogenic spillag

35、e.Further parts of ISO 20088 are planned for future publication: Part 2 : Vapour phase; Part 3: High pressure jet release.DIN EN ISO 20088-1:2017-01 EN ISO 20088-1:2016 (E)5 CAUTION The attention of all persons concerned with managing and carrying out cryogenic spillage testing is drawn to the fact

36、that liquid nitrogen testing can be hazardous and that there is a danger of receiving a “cold burn” and/or the possibility that harmful gases (risk of anoxia) can be evolved during the test. Mechanical and operational hazards can also arise during the construction of the test elements or structures,

37、 their testing and disposal of test residues. An assessment of all potential hazards and risks to health shall be made and safety precautions shall be identified and provided. Appropriate training and personal protection equipment shall be given to relevant personnel.1 ScopeThis document describes a

38、 method for determining the resistance to liquid cryogenic spillage on cryogenic spillage protection (CSP) systems. It is applicable where CSP systems are installed on carbon steel and will be in contact with cryogenic fluids.Liquid nitrogen is used as the cryogenic medium since it has a lower boili

39、ng point than liquid natural gas or liquid oxygen and it is not flammable. Additionally, it can be safely used for experiment.Future parts of the standard will cover vapour phase and jet exposure conditions.The test laboratory is responsible to conduct an appropriate risk assessment according to loc

40、al regulation in order to consider the impact of liquid and gaseous nitrogen exposure to equipment and personnel.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
