Wool - Determination of fibre diameter - Projection microscope method (ISO 137:2015)

Status: Valid

This International Standard specifies the procedure and the measurement conditions for the determination of the wool fibre diameter using a projection microscope.The method is suitable for wool fibres in any form and also for other fibres of reasonably circular cross-section. (In the case of dyed, bleached or finished fibres, the diameter might be different from that of fibres not subjected to such treatments. The estimates of fibre diameter obtained at the various stages of processing one lot of wool will not necessarily be the same.)
