The work of preparing
15、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 liaiso
16、n 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 main task of tec
17、hnical 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. Attention is dra

22、 BSI v Introduction Compression moulding of SMC and BMC differs from that of all other compression-mouldable reinforced thermosetting materials. Because of the maturation process which typically takes place before moulding and the ability of the compound to flow during moulding, special procedures n
23、eed to be used for the production of test plates from these compounds. Two different methods are given for preparing the mould charge: method A for moulding without the material flowing in the mould and method B for moulding so that the material flows in the mould. For engineers designing new moulds
24、, knowledge of the anisotropy imparted to the moulding under defined moulding conditions is essential. It is therefore necessary for the test plates from which test specimens will be cut to be manufactured under comparable conditions. BS ISO 12688:2004 Licensed Copy: sheffieldun sheffieldun, na, Mon
