标准范围
This document specifies a qualitative and quantitative procedure to determine the composition of
animal hair fibre blends (made of wool, cashmere, yak, alpaca, camel or angora) by LC-MS without
protein reduction.
NOTE 1 The composition of non-animal hair fibres can be measured by ISO 1833 (all parts). Both results are combined to determine the total fibre composition.
The method is based on a preliminary identification, by light microscopy, of all fibres in the blend on the basis of their morphology, according to ISO/TR 11827 . It is not applicable if fibres of the same animal species (such as blends of cashmere and mohair) are present.
NOTE 2 In this case, the quantitative analysis is performed using microscopical analysis [for example,
ISO 17751 (all parts)].
