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 represented on that committee. International organizations, govern- mental 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the Iso Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 7617-3 was prepared by Technical Committee ISO/TC 45, Rubberand rubber products. ISo 7617 consists of the following parts, under the general title Plastics-coated fabrics forupholstery: Part 1:Specification forPVC-coatedknitted fabrics Part 2: Specification for PVC-coated woven fabrics Part 3: Specification for polyurethane-coated woven fabrics Annexes A and B of this part of IS 7617 form an integral part of the standard. ?
