8 Test specimen sampling and preparation

8.1 General

The test specimen shall be selected based on the following criteria: Parts of the textile article;

Nature of the fibre components (fibre composition); Printed materials; Colours.

Prepare the test specimen by cutting in order to obtain a total mass of 1 g. For specimens to be submitted to colorant extraction (9.1) cut into strips (if apparatus described in 7.1 is used) or cut into small pieces if other apparatus is used or for specimens to be submitted only to reductive cleavage (9.3).

8.2 Textile article

If the textile article is a semi-manufactured product, such as yarns, fabrics, etc., cut out test specimens from it. If the textile article is composed of several parts of textile products, such as a garment, cut out test specimens from all the parts of the textile article that have direct and prolonged contact to skin or mouth, which can be: principal fabric(s); lining(s); pocket fabric(s); embroideries;

label(s) for textile article; drawstring(s); fastener(s); false fur; sewing threads.

If the mass of some parts (e.g. labels, sewing threads, embroideries of small size) does not reach the mass (1 g) to be tested, gather identical parts when possible. If the total mass of material is below 0,5 g, this material is defined as a minor component. (See NOTE 2, Annex C.) Below 0,2 g of material the analysis is omitted. Embroideries shall be weighed with the ground fabric.

8.3 Fibre composition

textile components so that the possible use of disperse dyestuffs can be determined. Table 2 summarizes the four cases:
