The work of preparing International Standards is normally carried out t
11、hrough 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 liaison with ISO, also take part in the work. ISO colla
12、borates 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 technical committees is to prepare International Sta
13、ndards. 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 drawn to the possibility that some of the elements o

ISO 2000 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 3, Raw materials (including latex) for use in the rubber industry.

17、become available, and significant developments have taken place in the supply of raw natural rubber, especially in relation to constant-viscosity (CV) grades. Rather than continuing to closely specify a limited number grades possibly restricting future developments it was felt that a more open appro
18、ach was appropriate, providing guidance and assistance to those parties (such as producers, suppliers and purchasers) involved in the specification of requirements for technically specified rubber rather than imposing potentially inappropriate limits on the TSR available. This guide encompasses rubb
19、ers that are typically more closely defined elsewhere, in more precise specifications. Reference may need to be made to such specifications in particular cases.
