Full Description

This International Standard specifies a method for determining the acid content of a wool sample, expressed as a percentage by mass.

This method is applicable to undyed wool in any form, for example loose fibre, sliver, yarn or fabric. It is also applicable to dyed wool when the amount of dye extracted during the test does not interfere with the determination of the end-point of the titration.
