22、, reference materials, quality control. EN ISO 105-B08:1999 BSI 04-2000iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO t
23、echnical 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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates clos
24、ely with the International Electrotechnical 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 least 75
25、 % of the member bodies casting a vote. International Standard ISO 105-B08 was prepared by Technical Committee ISO/TC 38, 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 pu
26、blication 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. “Section A01”). These sections are now being republished as separate documents, themselves designated “parts” but retaining their ea
27、rlier alphanumeric designations. A complete list of these parts is given in ISO 105-A01. Annex A and Annex B of this part of ISO 105 are for information only. iv blank EN ISO 105-B08:1999 BSI 04-20001 1 Scope This part of ISO 105 describes a method for carrying out quality control of production batc
28、hes of the blue wool reference materials 1 to 7 which are to be used in the appropriate parts of ISO 105-B series of test methods for colour fastness to light. The method specifies one procedure for instrumental assessment of the evenness of dyeing and two procedures for assessing the fading charact
29、eristics of the reference materials, one of which uses visual assessment techniques and the other instrumental assessment. The characteristics of the reference material(s) under test then are compared with the characteristics of master reference material(s). The method is applicable to all dyed wool
30、 fabrics intended for use as reference materials 1 to 7 (see ISO 105-B01:1994, subclause 4.1.1). NOTE 1This method is not suitable for blue wool reference 8, since the time required to fade to grey scale 4 and grey scale 3 contrasts would be inordinately long. An alternative method is under consider
31、ation for application to blue wool reference 8. NOTE 2The method given is based on ISO 105-B02, which is considered internationally to be the most widely employed method for testing colour fastness to light and to be representative of all methods where the use of blue wool references is specified.

42、e three specimens from each dyed piece of blue wool reference material under test. These specimens shall be approximately 300 mm in length across the full width of the material and shall be taken from the head end (H), the middle (M) and the tail end (T) of the piece. 6 Procedure 6.1 Evenness of dye
43、ing 6.1.1 Fold the specimen under test as many times as necessary to form an opaque mass (at least four thicknesses are recommended) and mount it wrinklefree in the spectrophotometer sample holder. Each of the three specimens shall be tested at the following three positions: a) in the centre (C); b)
44、 at a distance of 150 mm from the left-hand selvedge (L); c) at a distance of 150 mm from the right-hand selvedge (R). 6.1.2 Adjust the spectrophotometer to large aperture and the light beam to include the specular component and, if optional, the ultraviolet component, using illuminant D65 and 10 ob
45、server. NOTE 8If these measurement conditions are unobtainable, report the measurement conditions used see 7 e). 6.1.3 Measure and record the reflectance values at the appropriate wavelengths. Take four readings for each measurement, rotating the specimen through 90 between readings, and use the mea
46、n of these four readings for the value of the measurement to be used in the calculations in 6.1.4. 6.1.4 Calculate the colour differences %Ecmc determining evenness of dyeing using the CMC (l : c) colour difference formula (see ISO 105-J03) with lightness (l) set equal to 2 and chroma (c) set equal
47、to 1, i.e. CMC 2 : 1. Colour differences at the following positions shall be calculated: 6.2 Fading characteristics 6.2.1 Mounting of specimens Mount two specimens from the middle portion (M) (see clause 5) of the reference material under test immediately above and below a specimen of the appropriat
48、e master reference material (4.7) mounted in the centre of the exposure card (see Figure 1). The specimens shall have the dimensions specified in ISO 105-B02:1994, subclauses 5.1 and 5.3. Mask the centre third of the mounted specimens with an opaque cover (4.4) AB, as shown in Figure 2 a). 6.2.2 Exp
49、osure of specimens Set the fading apparatus (4.3) to normal conditions of black-panel temperature and effective humidity as specified in ISO 105-B02:1994, subclause 6.2 a), using the procedure specified in ISO 105-B02:1994, subclause 7.1, and the humidity test control (4.6). Expose the mounted specimens in the fading apparatus until a contrast between the exposed and unexposed areas of the master reference material is observed which is equivalent to step 4 on the grey scale for assessing change in colour (4.8).
