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. It includes seven optional procedures based on different methods of conditioning and preparation and different recommended allowances. Since the different procedures do not give the same values, it is essential that the procedure to be used is accepted by all parties interested in the test results. While this method is designed solely for the determination of mass per unit length of yarn, it is frequently desirable to combine this determination with tests for strength and/or etsts for commercial mass. If, in such case, skein lengths other than those specified are used, the length used, and any special corrections based on it, must be accepted by all parties interested in the test results. This method is applicable to: a) single yarns (spun, monofilament or multifilament); b) folded (plied) yarns; c)cabled yarns.
