The work of developing International Standards is carried out through Iso Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up 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. to the Member Bodies for approval before their acceptance as International StandardsbytheISOCouncil. International Standard 1SO 858 was drawn up by Technical Committee ISO/TC 38, Textiles, and circulated to the Member Bodies in October 1972. It has been approved by the Member Bodies of the following countries : Australia Hungary Romania Belgium India South Africa, Rep. of Bulgaria Iran Sweden Canada Israel Switzerland Czechoslovakia Italy Thailand Denmark Netherlands Turkey Finland NewZealand United Kingdom France Poland U.S.S.R.

The new designation will consist principally in naming the 4.1.1 General usage, complete designation resultant linear density. The complete designation of a netting yarn shall comprise, in the order given, the following five characteristics : 1SCOPE a) the linear density of the single yarn, expressed in This International Standard specifies a method for the designation of netting yarns for fishing nets by the use of tex; the nominal linear densities of the single yarncomponents b) the number of single yarns in the first folid; or of their resultant linear density, expressed in tex. c) 1) the number of folded yarns in the finished product, or,if suitable, 2 FIELDOF APPLICATION 2) the number of folded yarns, then cabled yarns, As a generaf rule, netting yarns designated by their linear in the finished product; density or their resultant linear density are usualiy grey d) the resultant linear density, expressed in tex; yarns without any preparation. e) the final twist direction of the finished product. If theindication of resultantlineardensitytakesaccount of any effects of chemical or physical treatment, this shall be The first three characteristics shall be joined to each other mentioned. by the multiplication sign (X); (if suitable, the number of cabied yarns is joined likewise to the number of folded 3REFERENCES yarns by themulitiplication sign).The last two characteristics shall be separated from the first three by a semi-colon (:). iso 2, Textiles - Designation of the direction of twist in yarnsandrelatedproducts.
