Wool -- Determination of acid content
This standard was last reviewed and confirmed in 2019. Therefore this version remains current.
The 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. The determined value is expressed as a percentage by mass.
