This document specifies a qualitative and quantitative procedure to determine the composition of animal hair fibre blends by LC-MS without protein reduction.

The composition of non-animal hair fibres can be measured by ISO 1833- series; then both results are combined to determine the whole composition of fibres.

The method is based on a preliminary identification of all fibres in the blend on the basis of their morphology, by light microscopy. In case of fibres of the same animal species are present (e.g. blends of cashmere and mohair), the method is not applicable and the quantitative analysis can be performed using microscopical analysis (e.g. ISO 17751- series).

This document specifies a method of test for measuring the force required to separate, by stripping, two plies of fabric bonded with rubber, or a rubber layer and a fabric ply bonded together.

The method is applicable when the ply surfaces are approximately plane or when they are in the form of a cylinder having an internal diameter greater than approximately 50 mm. The method is not applicable when the ply surfaces contain sharp bends, angles or other gross irregularities which cannot be excluded when cutting out test pieces.

This document does not apply to coated fabrics, which are tested in accordance with ISO 2411, or textile conveyor belts, which are tested in accordance with ISO 252.
