The work of preparing International Standards is normally carried out through ISO technical committees. Each mem
23、ber body interested in a subject for which a technical committee has been established has the right to be 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 El
24、ectrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting
25、 a vote. International StandardISO105-A05 was prepared by Technical Committee ISO/TC38, Textiles, Subcommittee SC 1, Tests for coloured 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 1
26、985. Each part contained a series of “sections”, each designated by the respective part letter and by a two-digit serial number (e.g. “Section A01”). These sections are now being republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric designations. A
27、 complete list of these parts is given inISO105-A01.iv blankENISO105-A05:1997 BSI 10-1999 1 1 Scope This part ofISO105 specifies an instrumental method for assessing the change in colour of a test specimen in comparison to an identical untreated reference, and the calculations undertaken to convert
28、the instrumental measurements into a grey scale rating. This method is intended as an alternative to the many national methods for visual evaluation of the effect of a colour fastness test on any textile material. NOTE 1There may be a difference between instrumental and visual assessments of specime
29、ns due to fluorescence, and/or other factors. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part ofISO105. At the time of publication, the editions indicated were valid. All standards are subject to revision, an
30、d parties to agreements based on this part ofISO105 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 105-J03:1995, Textiles Tests for colour f

CIE Publication No. 15.2, Colorimetry, 2nd ed.,1986 1) . 3 Principle The colour of the specimen which has been subjected to the colour fastness test and the colour of an identical untreated specimen are measured instrumentally. The CIELAB coordina
32、tes for lightness L*, chroma and hue h abare determined for both specimens, and the CIELAB differences %L * , andare calculated and converted to a grey scale rating by means of a series of equations. 4 Apparatus 4.1 Spectrophotometer or colorimeter, meeting any one of the illuminating and viewing co
33、nditions for reflecting specimens as described in CIE Publication 15.2, subclause 1.4. 5 Test specimen Choose a representative sample of material which has been subjected to a colour fastness test, of adequate size to fit the sample holder of the instrument used and having no visible defects. Back a
34、 single layer of the test specimen with an opaque white material containing no fluorescent whitening agents (FWA). Both the test specimen and the untreated reference shall be backed in an identical manner. NOTE 2Alternatively, back the test specimen with a number of thicknesses of the identical untr
35、eated material sufficient to give an acceptably opaque specimen. 6 Test procedure 6.1 From the untreated material, prepare a reference consisting of the same number of thicknesses of material as that used to prepare the test specimen (see clause5). Mount the reference in the sample holder and measur
36、e its colour values with the instrument (see4.1). From the instrument system, obtain CIE tristimulus values using CIE illuminant D65 and 10 observer. Calculate the CIELAB L*, and h abvalues using the data obtained, as specified inISO105-J03. NOTE 3Permitted illuminant/observer alternatives for color
37、imetric calculations are: D65/2 ; C/2 ; C/10 . 6.2 Measure the colour of the specimen (see clause5) in the same manner and calculate the CIELAB L*, and h abvalues. 7 Calculation of change in colour 7.1 Calculate the differences in lightness %L*, chromaand huebetween the reference and specimen from t
