This document specifies three methods for the determination of the number of threads per centimetrein woven fabrics. Any of the three methods can be used, the choice depending on the character of thefabric. However, in case of dispute method A is recommended.Method A: Dissection of fabric, suitable for all fabrics. This is the most laborious method but has fewerlimitations than the others; in particular, it is the only one that is really suitable for the examination ofcertain folded structures and other complicated weaves.Method B: Counting glass, suitable for woven fabrics with more than 50 threads per centimetre.Method C: Traversing thread counter, suitable for all fabrics.Where the number of threads per centimetre is low, it may be convenient to express the results as thenumber of threads per decimetre.
