This International Standard specifies common methods for the quantitative microscopical analysis of various mixtures of fibres. The methods described is based on the using of a light microscope (LM) or a Scanning Electronic Microscope (SEM), on the measurements of the fibre apparent diameter (preparation of longitudinal views) or on the measurements of fibre section area (preparation of cross views), depending on the section shape of the fibres.

NOTE When the section shape is circular or almost circular, the longitudinal views are appropriate. For the other section shapes, the cross views are adequate. Pictures of section shapes of fibres can be found in ISO/TR 11827.

The given procedures may be applied to fibres in any textile form when mixtures of fibres cannot be separated by manual methods or by chemical methods.

For examples, such mixtures are cashmere and wool, cotton and flax, flax and hemp.

If it is practicable to separate chemically the components, the method described in the individual parts of ISO 1833 should be used in preference to the microscopical methods.
