The work of preparing International Standards is
9、 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
10、 in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to pr
11、epare International Standards. 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. Attention is drawn to the possibility that
12、 some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1107 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 38, Textiles, in acc
13、ordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). Throughout the text of this document, read “.this European Standard.“ to mean “.this International Standard.“. This second edition cancels and replaces the first edition (ISO 1107:1974), which has been techni

21、 2003 All rights reserved 1 1 Scope This European Standard gives the principal terms relating to netting for fishing nets, together with their definitions or, in some cases, the method of expressing dimensions. 2 Normative references This European Standard incorporates by dated or undated reference,
22、 provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated i
23、n it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN ISO 1530:2003, Fishing nets Description and designation of knotted netting (ISO 1530:2002). ISO 858, Fishing nets Designation of netting yarns in the Tex System.
24、 ISO 1139, Textiles Designation of yarns. 3 Terms and definitions For the purposes of this European Standard the following terms and definitions apply. 3.1 netting a meshed structure of indefinite shape and size composed of one yarn or of one or more systems of yarns interlaced or joined, or obtaine
25、d by other means, for example by stamping or cutting from sheet material or by extrusion 3.2 netting yarn all types of yarns1) suitable for the manufacture of netting NOTE 1The principal types of netting yarns are twines. The latter are defined below. The size of netting yarn is indicated by its lin
26、ear density expressed in the unit tex of the Tex system in accordance with ISO 858. The size of the final product is expressed by the “resultant linear density” in accordance with ISO 1139. NOTE 2The resultant linear density is the reciprocal of “runnage” which expresses the length per unit mass, in
27、 metres per gram or per kilogram, for example. 3.2.1 netting twine the product of one twisting operation embracing two or more single yarns or monofilaments 3.2.2 cabled netting twine the product of further twisting operations embracing two or more netting twines 1)The definition in ISO 1139 denotes
28、 “yarn” folded yarn and cabled yarn as a general term embracing a single yarn (including monofilament) multiple wound yarns.

42、netting yarn or longest axis of the mesh NOTEDirection in knotless netting can usually be related to the general course of the netting yarn, but this is not always so because the general course of the netting yarn cannot in every case be determined. Usually, the direction of the longest possible axi
43、s of the mesh is parallel to the general course of the netting yarn. If the two axes are equal, the direction of the netting cannot be determined and the mesh size may be determined in either direction. 3.6.1.1 N-direction (depthwise) the direction at right angles to the general course of the nettin
