The work of preparing International Standards is normally carried out through isO technical committees.Eachmemberbodyinterestedinasubjectforwhichatechnicalcommitteehasbeenestablishedhas liaison with sO, a 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 International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 13002 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and reinforcement fibres. @ISO1998 Al rights reserved.

It does not apply to discontinuous fibre products pyrolized in the form of staple yarns, woven fabrics, braids, knits, mats, etc. 1.3 The types of filament yarns are differentiated from each other by a classification system based on appropriate levels of the designatory properties: a) tensile modulus of elasticity; b) tensile strength; c) linear density. 1.4 It is not intended to imply that materials having the same designation give the same performance. This International Standard does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. 1.5 In order to specify a filament yarn for a particular application or to ensure reproducible processing, additional 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
