10、rnational organizations, governmental and non-governmental, 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. International Standards are drafted in accordance with th

11、e rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval b

26、t is text that describes elements of the design that are indispensable or contains theconformance language keywords: “shall“, “should“, or “may“. Informative text is text that is potentiallyhelpful to the user, but not indispensable, and can be removed, changed, or added editorially withoutaffecting

27、 interoperability. Informative text does not contain any conformance keywords. All text in this document is, by default, normative, except: the Introduction, any section explicitly labeledas “Informative“ or individual paragraphs that start with “Note:” The keywords “shall“ and “shall not“ indicate

28、requirements strictly to be followed in order to conform tothe document and from which no deviation is permitted. The keywords, “should“ and “should not“ indicate that, among several possibilities, one is recommendedas particularly suitable, without mentioning or excluding others; or that a certain

29、course of action ispreferred but not necessarily required; or that (in the negative form) a certain possibility or course ofaction is deprecated but not prohibited. The keywords “may“ and “need not“ indicate courses of action permissible within the limits of thedocument. The keyword “reserved” indic

30、ates a provision that is not defined at this time, shall not be used, and maybe defined in the future. The keyword “forbidden” indicates “reserved” and in addition indicates that theprovision will never be defined in the future. A conformant implementation according to this document is one that incl

31、udes all mandatory provisions(“shall“) and, if implemented, all recommended provisions (“should“) as described. A conformantimplementation need not implement optional provisions (“may“) and need not implement them asdescribed. 3 Normative References The following standards contain provisions which,
