Standards Proposed for adoption

Parent Category: Standards Proposed for adoption

The Kenya Bureau of Standards intends to adopt the International Standards as detailed here below.

Number: ISO 1139:1973

Title:  Textiles — Designation of yarns

Scope: This International Standard specifies two methods of indicating the composition of yarns, whether single, folded, cabled or multiple wound. The notation comprises linear density indicated in the Text System, number of filaments in filament yarns, direction and amount of twist, and number of folds.

Number: ISO 1144:2016

Title:  Textiles — Universal system for designating linear density (Tex System)

Scope: This International Standard gives the principles and recommended units of the Tex System for the expression of linear density and includes conversion tables for calculating the tex values of numbers or counts in other systems together with a statement of the procedure for the implementation of the Tex System in trade and industry.

Number: ISO 2060:1994

Title:  Textiles — Yarn from packages — Determination of linear density (mass per unit length) by the skein method

Scope: This International Standard specifies a method for the determination of the linear density of all types of yarn in package form, with the exception of any yarn that may be the subject of a separate International Standard.

Number: ISO 2060:1994

 

Number: ISO 2061:2015

Title:  Textiles — Determination of twist in yarns — Direct counting method

Scope: This International Standard specifies a method for the determination of the direction of twist in yarns, the amount of twist, in terms of turns per unit length, and the change in length on untwisting, by the direct counting method.

Number: ISO 2061:2015

 

Number: ISO 2062:2009

Title:  Textiles — Yarns from packages — Determination of single-end breaking force and elongation at break using constant rate of extension (CRE) tester

Scope: This International Standard specifies methods for the determination of the breaking force and elongation at break of textile yarns taken from packages. This International Standard specifies methods using constant rate of specimen extension (CRE) tensile testers.

Number: ISO 2062:2009

 

Number: ISO 6741-1:1989

Title: Textiles — Fibres and yarns — Determination of commercial mass of consignments — Part 1: Mass determination and calculations

 Scope: This part of  ISO 6741 specifies methods for the determination of the commercial mass of homogeneous consignments of those textile fibres and yarns composed of a single generic species listed in part 4.

The methods specified in this part of  ISO 6741 do not apply to beamed yarns, to coated yarns, to fibres and yarns put up for retail sale or to fibre blends.

Number: ISO 6741-1:1989

 

Number: ISO 6939:1988

Title: Textiles — Yarns from packages — Method of test for breaking strength of yarn by the skein method

Scope: This International Standard specifies a method for the determination of the breaking strength of yarn by the skein method. It is applicable to spun single and folded yarns of any fibre or mixture of fibres manufactured by any spinning system. It is not recommended for testing filament yarns; for testing glass yarns; for more complex structures such as cabled yarns or cords; for yarns that stretch more than 5 % when the tension increases from 0,5 cN to 1,0 cN per unit of linear density of the yarn in tex; nor is it applicable to those yarns having a diameter so great as to prevent the winding of the skein in two even layers

Number: ISO 6939:1988

 

Number: ISO 16549:2021

Title: Textiles — Unevenness of textile strands — Capacitance method

Scope: This document describes a method, using capacitance measuring equipment, for determining the unevenness of linear density along the length of textile strands.

The method is applicable to tops, slivers, rovings, spun yarns and continuous filament yarns, made from either natural or man-made fibres, in the range of 4 tex (g/km) to 80 ktex (kg/km) for staple-fibre strands and 1 tex(g/km) to 600 tex (g/km) for continuous-filament yarns. It is not applicable to fancy yarns or to strands composed fully or partly of conductive materials such as metals; the latter requires an optical sensor, and to raw silk filaments which are tested according to a specific standard.

Number: ISO 16549:2021

 

Number: ISO 17202:2002

Title: Textiles — Determination of twist in single spun yarns — Untwist/retwist method

Scope: This International Standard specifies a method for the determination of the direction of twist in single yarns and the amount of twist, in terms of turns per unit length, by the indirect untwist/retwist method.

Number: ISO 17202:2002
