The wor
5、k 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 represented on that committee. International organizations, governmental and non-governme
6、ntal, 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 the rules given in the ISO/IEC Directives, Part 2. The m
7、ain 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 by at least 75 % of the member bodies casting a vote. A

12、(UP) resin. Page 6, 7.4.7 Replace the subclause with the following: Steadily increase the hydrostatic pressure to 2,0 times the nominal pressure of the joint, expressed in bars, and maintain within 2 % for not less than 24 h. Page 6, 7.5.1 Replace the subclause with the following: Steadily increase
13、the hydrostatic pressure to 2,0 times the nominal pressure of the joint, expressed in bars, and maintain within 2 % for not less than 24 h (see Table 1). Page 7, 7.5.7 Replace the subclause with the following: Either increase the pressure to 2,5 times the nominal pressure of the joint, expressed in
14、bars, and maintain that pressure within 2 % for 100 h (see Table 1) or increase the pressure to 3 times the nominal pressure of the joint, expressed in bars, and maintain that pressure within 2 % for 6 min. During either of these times the joint shall not fracture. Leakage of the joint does not cons
15、titute a failure. Page 8, Table 1 Replace Table 1 with the following, in which some of the table headings have been updated and the test pressure for the resistance to bending and internal pressure and resistance to internal pressure have changed from 1,5 times PN to 2,0 times PN: ISO 8533:2003/Amd.
