The work of prepari

22、ng 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-governmental, in lia

23、ison 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 Dir

24、ectives, 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 s

25、ome 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 of patent decla

29、aterials can be determined. 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 s

30、ubstantially less than that 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 larg

32、UTION The attention of all persons concerned with managing and carrying out cryogenic spillage testing is drawn to the fact 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 du

33、ring the test. Mechanical and operational hazards can also arise during the construction of the test elements or structures, 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.

34、Appropriate training and personal protection equipment shall be given to relevant personnel.1 ScopeThis document describes a 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 s

35、teel and will be in contact with cryogenic fluids.Liquid nitrogen is used as the cryogenic medium since it has a lower boiling 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 pha

36、se and jet exposure conditions.The test laboratory is responsible to conduct an appropriate risk assessment according to local 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 i

44、roduces a material to test4 Test configurations4.1 GeneralThere is one basic configuration under which the test can be conducted. This is a liquid configuration where the material to be tested is rapidly exposed to liquid nitrogen in a pool at a temperature of 196 C. For reasons of clarity, flexible

45、 hoses used for fume extraction are not shown in Figures 1 to 4 below.4.2 Sample holderSamples will be tested in a sample holder with exact dimension as specified in ISO 22899-1:2007, Figure 11.2 ISO 2016 All rights reservedBS EN ISO 20088-1:2016ISO 20088-1:2016(E)5 Construction of the test items an

46、d substrates5.1 GeneralThe key items required for the test are: a liquid nitrogen injection point; a sample holder; the insulation part.It is important to reduce vapour generation during the liquid nitrogen dumping. Flexible hoses are to be used without forced ventilation.5.2 MaterialThe material no

47、rmally used is a 10 mm thick steel plate complying with ISO 630-1, Grade Fe 430. An all welded construction shall be used and all welds shall be 5 mm fillet and continuous unless otherwise stated. All dimensions are in millimetres and, unless otherwise stated, the following tolerances shall be used:

48、 whole number 1,0 mm; decimal to point, 0 mm 0,4 mm; decimal to point, 00 mm 0,2 mm; angles 0 30”; radius 0,4 mm.5.3 Release tankThe liquid nitrogen is contained within a tank of a constant surface area either a square base of 750 mm or circular base of 846 mm diameter. The release orifice shall be

49、100 mm in diameter.When there is 250 l of stable non-bubbling liquid nitrogen within the tank, the test is ready to start. The release tank shall be constructed of cryogenic resistant stainless steel and externally insulated for personnel protection.
