CAN/CGSB-4.2 No. 73.4-M91/ ISO 2916: 1975 (R2013)

This National Standard of Canada is equivalent to International Standard ISO 2916:1975. This International Standard specifies a method for the determination of the alkali content of wool. The method is applicable to undyed wool in any form; for example, loose fibres, card sliver, tops, yarn or fabric. It can be used with dyed wool if the amount of dye extracted in the course of the test does not affect the determination of the end-point of the titration.
