标准范围
This International Standard specifies a method for the determination of the mean diameter of woolfibres, 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, openstate. It provides a method particularly suitable for combed slivers. The dichloromethane extractablematter content of the specimen must not exceed 1,0 %. It is applicable to oil-combed slivers after cleaningwith an organic solvent.The method described in this International Standard is less accurate for lambswool and for wool whichis appreciably medullated (see Annex D) and heavily dyed wool.
