18、 of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.

19、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 develop this document and those

20、 intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

26、ile articles. To support international and national regulations the development of a test method is very important and this part of ISO 16373 does just that.The ISO 16373 series deal with dyestuffs used in textile for qualification and quantification. ISO 16373-11)includes the definition of the dyes

27、tuff, and classes the description of some procedures to identify qualitatively the dyestuff class used in textile material. The other parts of ISO 16373 are related to the quantification of some dyestuffs. In ISO 16373-2, the principle of the test method is based on extraction using pyridine-water s

28、olution, which has been found to be the most efficient solution to extract a large range of dyestuffs, including allergenic and carcinogenic dyestuffs. In this part of ISO 16373, the principle of the test method is based on extraction using triethylamine-methanol solution. This solution has been fou

29、nd to be efficient at extracting some dyestuffs in some cases.Additional information related to the recovery rate (to characterize the extraction efficiency) obtained from the application of ISO 16373-2 and this part of ISO 16373 is summarized in ISO 16373-1:, Annex B.It is important to note that th

30、ere are other test methods related to azo dyes, for which a reduction of the extracted azo dyes leads to the release of some aromatic amines to be detected and determined using chromatography.671) To be published.
