ISO 13002 pdf download.Carbon fibre — Designation system for filament yarns 1 Scope 1.1 This International Standard establishes a system of designation for filament yarns of carbon fibre which may be used as the basis for specifications. 1.2 This designation system is applicable to filament yarns used for the reinforcement of polymer composites. 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 requirements may be given in data block 3 (see clause 3). 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 1 889:1 997, Reinforcement yarns — Determination of linear density .

For unambiguous designation, the individual-item block is subdivided into three data blocks comprising the following information: – Data block 1 : Identification of the carbon fibres by information about the precursor yarn and product form (see 3.1 ). – Data block 2: Designatory properties (see 3.2). – Data block 3: For the purpose of specifications, a third data block may be containing additional information (see 3.3). The first character of the individual-item block...
