9、n) is a worldwide federation of national standards bodies (ISO member bodies). The 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 rep
10、resented on that committee. International 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 a
11、re drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting
12、a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 12572 was prepared by the European Committee for Sta
13、ndardization (CEN) in collaboration with ISO Technical Committee TC 163, Thermal insulation, Subcommittee SC 1, Test and measurement methods, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). Throughout the text of this standard, read “.this European S
14、tandard.“ to mean “.this International Standard.“. Annexes A to G form a normative part of this International Standard. Annexes H and J are for information only.
