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 voting. Publication as an Inter- national Standard requires approval by at ieast 75 % of the member bodies casting a vote. International Standard iso 9866-2 was prepared by Technical Committee ISO/TC 38, Textiles, Sub-Committee SC 2, Cleansing, finishing and water resistance tests. Iso 9866 consists of the following parts, under the e general title Textiles - Effect of dry heat on fabrics under low pressure: Part 1:Procedure for dry-heat treatment of fabrics Part 2: Determination of dimensional change in fabrics exposed to dry heat C ISO 1991 All rights reserved.
