ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the techni

International StandardISO105-A06 was prepared by Technical Committee ISO/TC38, Textiles, Subcommittee SC 1, Tests for coloured

23、 textiles and colorants. ISO 105 was previously published in thirteen “parts”, each designated by a letter (e.g. “Part A”), with publication dates between 1978 and 1985. Each part contained a series of “sections”, each designated by the respective part letter and by a two-digit serial number (e.g. “

24、Section A01”). These sections are now being republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric designations. A complete list of these parts is given inISO105-A01. Annex A andAnnex B of this part ofISO105 are for information only. Descriptors: Te

26、ISO105-A01:1994. This method is applicable to 1/1 standard depth of colour only. Its use for other standard depths is under consideration. NOTE 1Specimens which this colorimetric method indicate to be of 1/1 standard depth may differ from specimens which are visually assessed to be of 1/1 standard d

27、epth by comparison with physical standards known to be of 1/1 standard depth. These differences may lead to differences in the results of tests applied subsequently. It is recommended that the method of assessment of 1/1 standard depth, i.e. ISO105-A06 or visual, be included in the report of tests s

28、ubsequently applied. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this part ofISO105. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements base

29、d on this part ofISO105 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. CIE Publication No. 15.2:1986 Colorimetry, (second edition) 1) . 3 Principl

30、e The CIELAB colour coordinates L* (lightness), C* ab(chroma) and h ab(hue) of the dyeing to be checked for 1/1 standard depth are measured instrumentally. The lightness L SDfor 1/1 standard depth is calculated by means of a given equation. The lightness difference %L between the measured lightness

31、L* of the dyeing and the calculated lightness L SDrequired for 1/1 standard depth is determined to decide if the dyeing represents 1/1 standard depth. 4 Apparatus 4.1 Spectrophotometer or colorimeter, meeting any one of the definitions described in CIE publication15.2, subclause 1.4. 5 Test specimen

32、 Cut a representative specimen of the dyeing to be checked for 1/1 standard depth and mount it on an opaque white backing which has not been pretreated with a fluorescent whitening agent. The size of the specimen shall fit at least the aperture of the instrument to be used for measurement. A minimal

33、 specimen size of50mm 50mm is recommended. When presented to the instrument, the specimen shall be of sufficient thickness to be opaque, otherwise light will pass through the specimen and reflect off the backing material. Check the opacity of the specimen by measuring it over a black background and

34、separately over a white background. If complete opacity cannot be achieved, then it is sufficient if the difference between the L* resulting from measurements over black and white backgrounds is less than0,2. 6 Procedure Place the test specimen against the sample port of the instrument in such a way

35、 that it provides a smooth surface and read the CIELAB coordinates L* (lightness), C* ab(chroma) and h ab(hue), using the CIE10 observer and illuminant D65. Take at least two readings, preferably from different areas of the test specimen, and average them. 7 Calculation 7.1 Calculate the lightness L
