This International Standard specifies a method for the determination of the mean diameter of wool fibres, using an apparatus which passes a current of air through a bundle of fibres.
This International Standard is applicable to clean, unmedullated wool fibres dispersed in a uniform, open state. It provides a method particularly suitable for combed slivers. The dichloromethane extractable matter content of the specimen must not exceed 1,0%. It is applicable to oil-combed slivers after cleaning with an organic solvent.
The method described in this International Standard is less accurate for lambswool and for wool which is appreciably medullated (see AnnexD) and heavily dyed wool.
