18、003 (E) 4 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, provisions from o
19、ther 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 in it by amendment
20、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. ISO 1139, Textile
21、s 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 obtained by other means,
22、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 linear density expres
23、sed 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 metres per gram o
24、r 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 “yarn” folded yar
25、n and cabled yarn as a general term embracing a single yarn (including monofilament) multiple wound yarns.

26、 netting yarns and/or netting twines 3.3 mesh a design formed opening, surrounded by netting material. There are several types of mesh shapes: 3.3.1 diamond mesh a mesh composed of four sides of the same length 3.3.2 square mesh a diamond mesh in which adjacent sides are at right angles 3.3.3 hexago
27、nal mesh a mesh composed of six sides, out of which the length of one pair of opposite sides can be different from that of the other four sides, in case of an irregular hexagon 3.4 size of mesh 3.4.1 length of mesh side (also referred to as half mesh) the distance between two sequential knots or joi
28、nts, measured from centre to centre when the yarn between those points is fully extended as shown in Figure 1 Licensed Copy: sheffieldun sheffieldun, na, Wed Nov 15 09:37:51 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN ISO 1107:2003 (E) 6 Figure 1 Length of mesh side NOTEIn hexagonal meshes two dif

30、en the centres of two opposite joints in the same mesh when fully extended along its longest possible axis (see definition 3.6.1.1).

36、1 general direction of the 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
37、of the longest possible axis 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 g
