IS 1315 : 2025 Textiles - Linear Density of Yarns Spun on Cotton System - Methods of Test
1 SCOPE
1.1 This standard prescribes two methods for determination of linear density of yarn spun on cotton system in cotton count and tex:
a) Method A - Evaluation of linear density by determining the mass of the conditioned yarn at equilibrium with the standard atmosphere for testing; and
b) Method B - Evaluation of linear density by determining the mass of the oven-dry yarn plus the commercial moisture regain.
1.2 This method is applicable to single, plied, and cabled yarns. In case of plied and cabled yarns, linear density is expressed in term of its resultant count.
