BRIEF HISTORY
The IS0 Recommendation R 858, Netting yams for fishing nets - Designation in the Tex
System, was drawn up by Technical Committee ISO/TC 38, Textiles, the Secretariat of which is
held by the British Standards Institution (BSI).
Work on this question by the Technical Committee began in 1963 and led, in 1966, to the
adoption of a Draft IS0 Recommendation.
In April 1967, this Draft IS0 Recommendation (No. 1239) was circulated to all the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial nature, by
the following Member Bodies :
India Spain
Australia
Iran Sweden
Austria
Belgium Israel Switzerland
Brazil Japan Thailand
Bulgaria Netherlands Turkey
Canada New Zealand United Kingdom
Denmark Norway U.S.A.
France Romania U.S.S.R.
Germany South Africa, Rep. of
Two Member Bodies opposed the approval of the Draft :
Czechoslovakia
Italy
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in October 1968, to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 858 October 1968
NETTING YARNS FOR FISHING NETS
DESIGNATION IN THE TEX SYSTEM*
INTRODUCTION
The designation of netting yarns for fishing nets in the Tex System will ultimately replace designations
made according to traditional systems.
The new designation will principally consist in naming the resultant linear density.
1. SCOPE
This IS0 Recommendation describes a method for the designation of netting yarns for fishing nets by
the use of their linear density or of their resultant linear density, expresse& in tex.
2. FIELD OF APPLICATION
As a general rule, netting yarns designated by their linear density or their resultant linear density are
usually grey yams without any preparation.
If the indication of resultant linear density takes account of any effects of chemical or physical treat-
ment, this should be mentioned.
