18、s page deliberately set blankEN ISO 105-G02:1997 BSI 2009 1 1 Scope 1.1 This part of ISO 105 specifies a method for determining the resistance of the colour of textiles of all kinds and in all forms, except loose fibres, to exposure to atmospheric oxides of nitrogen as derived from the combustion of
19、 chemically pure butane gas. 1.2 This method may be used for rating the colour fastness of dyes by applying the dye to textiles by a specified procedure and at a specified depth of colour and testing the dyed textiles. 2 Normative references The following standards contain provisions which, through
20、reference in this text, constitute provisions of this part of ISO 105. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 105 are encouraged to investigate the possibility of applying the most rece
21、nt editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

ISO 105-D01, Textiles Tests for colour fastness Part D01: Colour fastness to dry cleaning using perchloroethylene solvent. 3 Principle A specimen of the textile an
23、d a test-control fabric are exposed simultaneously to oxides of nitrogen from burnt-gas fumes until the test control shows a change in colour corresponding to that of a standard of fading. The change in colour of the specimen is assessed with the grey scale. If no colour change is observed in the sp
24、ecimen after one exposure period or cycle, exposure may be continued for either a specified number of periods or for the number of periods required to produce a specified amount of colour change in the specimen. 4 Apparatus and materials 4.1 Exposure chamber (see Annex A). 4.2 Test control (see Anne
25、x B). 4.5 Butane gas, chemically pure, and a suitable burner. Any gas burner may be used and either a yellow luminous or a blue-green flame is suitable, though the latter is to be preferred in order to minimize the formation of soot. A wire gauze placed above the flame at a distance which causes it
26、to be heated to some-where between red and white heat will increase the percentage of oxides of nitrogen and will thereby accelerate the fading of the test control and specimens. Brass, iron, Monel alloy and stainless-steel gauzes give practically the same results. 4.6 Urea, solution containing, per
27、 litre, 10 g of urea (NH 2 CONH 2 ), buffered to pH 7 by the addition of 0,4 g of sodium dihydrogen orthophosphate dihydrate (NaH 2 PO 4 2H 2 O) and 2,5 g of disodium hydrogen orthophosphate dodecahydrate (Na 2 HPO 4 12H 2 O), and containing 0,1 g or less of a rapid-wetting surface-active agent, for
28、 example sodium dioctyl sulfosuccinate. 4.7 If required, perchloroethylene, Stoddard solvent or trichloroethylene (see 5.4). NOTE 1 All the inhibitors available at present are soluble to some extent in water and therefore tend to be removed by washing. These inhibitors are in general not soluble in
29、the ordinary dry-cleaning solvents, and fabrics treated with suitable inhibitors should withstand several dry-cleanings without losing their resistance to gas fading provided the dry-cleaning operation does not not include spotting or sponging with water). The inhibitors also tend to lose their effi
30、ciency if the fabrics come into frequent contact with perspiration. 4.8 If required, 1993 AATCC 1)StandardReference(see 5.5), as specified in ISO 105-C06. Detergent WOB 5 Test specimens NOTE 2 When an acetate fabric is pressed with an iron which is hot enough to remove all wrinkles, there is a dange
31、r of sealing the surface of the fabric, which would increase the resistance to gas fading. This technique is not conducive to accurate test results and should be avoided on fabrics of this type. 5.1 If the textile to be tested is fabric, use a specimen measuring 40 mm 100 mm. 5.2 If the textile to b
32、e tested is yarn, knit it into fabric and use a specimen measuring 40 mm 100 mm. 5.3 For fastness to oxides of nitrogen in storage or use, use a specimen of the original fabric. 4.3 Standard of fading (see Annex B). 4.4 Grey scale for assessing change in colour, complying with ISO 105-A02. 1)America

BS EN ISO 105-G02:1997 EN ISO 105-G02:1997 2 BSI 2009 5.5 For fastness to oxid
34、es of nitrogen after washing (see note 1), unless a specific wash-test is specified, wash the test specimen in a detergent solution containing 5 g of AATCC reference detergent WOB per litre of water of approximately zero hardness for 10 min at 40 C, rinse in warm water and allow it to dry in the air
35、. Retain a specimen after washing and before testing to compare with the tested specimen. 6 Procedure 6.1 Freely suspend each specimen and a piece of the test control in the test chamber (4.1) so that they are not in contact with each other and do not come into direct contact with any hot metallic s
36、urface. If fewer specimens than are required to fill the chamber are to be tested, fill the chamber with cuttings of undyed fabric of the same kind. Light the gas burner (4.5) and adjust the flame and ventilating equipment so that the temperature in the chamber does not exceed 60 C. NOTE 3 Other thi
37、ngs being equal, the fading of the specimens will vary according to the temperature in the exposure chamber, which in turn depends upon the amount of gas consumed in a given period. Exposure for 8 h to 12 h at 60 C may cause as much colour destruction as exposure for 96 h at 21 C to 27 C. Apart from
38、 this, the temperature may vary somewhat in different parts of the exposure chamber from time to time. The fading of dyes on acetate, triacetate and polyester by oxides of nitrogen will occur at low relative humidities, as would be obtained in the conventional chamber at temperatures approaching 60
39、C. For other fibres such as nylon, viscose or cotton, it is necessary to use high humidities in order to produce results which correlate with service performance. A suggested procedure for raising the level of humidity in the chamber, if this is necessary, is to place containers of water on the floo
40、r of the chamber. If the humidity is raised by this or any other procedure, this shall be noted in the test report. Keep the specimens in the chamber until the test control shows a change in colour corresponding to that of the standard of fading (4.3), when compared in daylight or equivalent artific
41、ial illumination (see ISO 105-A01 ). 6.2 Remove the specimens from the test chamber and immediately make a preliminary assessment of the change in colour by the use of the grey scale for assessing change in colour (4.4). 6.3 Those specimens showing a colour change, a piece of the original textile fr
42、om which each specimen was taken, and the test control shall, without delay, be plunged into the buffered urea solution (4.6) for 5 min. They shall be squeezed out, thoroughly rinsed in water, and dried in air at a temperature not above 60 C. When dry, assess the change in colour of each specimen ag
43、ainst the portion of the original textile which has been treated with buffered urea solution, using the grey scale. If retained, store in the dark. 6.4 After the first cycle, return to the test chamber any specimens which do not show a colour change and which were not treated with the buffered urea
44、solution, along with a fresh piece of the test-control fabric, and continue the test until the second test control shows a change in colour corresponding to that of the standard of fading. 6.5 The procedure may be repeated either for a specified number of cycles or until the specimens show a specifi
45、ed amount of colour change. 6.6 After each exposure period, remove the specimens from the chamber and immediately compare them with the respective originals. 6.7 The effect on the colour of the specimens after any desired number of cycles can be expressed and defined by reference to the grey scale f
46、or assessing change in colour. 7 Test report The test report shall include the following particulars: a) The number and date of publication of this part of ISO 105, i.e. ISO 105-G02:1993; b) all details necessary for the identification of the sample tested; c) the numerical rating for the change in
47、colour of each specimen and the number of cycles for which it was exposed; d) the average temperature employed and, if humidity was increased, the method employed.5.4 For fastness to oxides of nitrogen after dry-cleaning (see note 1), use the method specified in ISO 105-D01. Immerse one specimen in
48、cold perchloroethylene (4.7) for 10 min, squeeze and allow it to dry in the air. If desired, Stoddard solvent or trichloroethylene may be substituted for perchloroethylene. Retain a specimen after dry-cleaning and before testing to compare with the tested specimen. BS EN ISO 105-G02:1997 EN ISO 105-
