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, governmental 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. Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 10371 was prepared by Technical Committee ISO/TC 61, Plastics, Sub-Committee SC 13, Composites and reinforce- mentfibres. ISO 1993 All rights reserved.
