Textiles. Quantitative analysis of animal fibres by microscopy. Cashmere, wool, speciality fibres and their blends Ingestion-build-48974 The safety integrity levels (SILs)1 Scope This International Standard specifies a method for the identification and quantitative analysis of wool and speciality animal fibres using both light microscopy (LM) and scanning electron microscopy (SEM). This standard is also applicable to blends of animal fibres and products made from them. NOTE 1 Difficulty may be encountered when attempting the analysis of deeply dyed or heavily pigmented fibres by LM. In such cases, mild dye stripping or
