Each member body interested in a subject for which a technical committee has been established has the right to be

25、represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to

In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the

36、traction are those used to colour with pigments or to dye cellulosic fibres (e.g. cotton, viscose), protein fibres (e.g. wool, silk), and synthetic fibres (e.g. polyamide, acrylic).Azo colorants accessible with extraction are those used to dye man-made fibres with disperse dyes. The following man-ma

49、 PrincipleAfter selection of a coloured test specimen from the textile article, the test specimen is tested according to the method of colorant extraction for disperse dyes and/or the method of direct reduction for the other classes of colorants (pigments and/or dyes).The application of one of the two methods is based on the nature of the fibre(s) of the test specimen (composed of pure fibre or of fibre blends) and the colour treatment (dyeing or printing process). When the method of the colorant extraction f
