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- 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 tmember bodies for voting. Publication as an Inter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IsO 9958-2 was prepared by Technical Committee iso/TC 10, Technical drawings, product definition and related documen- tation, Sub-Committee SC 9,Media and equipment for drawing and re- lated documentation. 9958 consists of the following ISO parts, under the general title Draughting media for technical drawings --- Draughting film with poly- ester base: Part 1: Requirements and marking Part 2: Determination of properties Annex A of this part of Iso 9958 is for information only ISO 1992 All rights reserved.
