24、wide federation 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 t
25、hat committee. 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. Draft International Standards adopted
26、by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 105-G03 was prepared by Technical Committee ISO/TC 38, Textiles, Sub-Committee SC 1,
27、 Tests for coloured textiles and colorants. This second edition cancels and replaces the first edition (included in ISO 105-G:1978), of which it constitutes a minor revision. ISO 105 was previously published in thirteen “parts”, each designated by a letter (e.g. “Part A”), with publication dates bet
28、ween 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 earlier alphanumeric
29、designations. A complete list of these parts is given in ISO 105-A01. Annex A and Annex B form an integral part of this part of ISO 105. Annex C is for information only.

31、 the resistance of the colour of textiles of all kinds and in all forms to the action of ozone in the atmosphere, both at ambient room temperatures with relative humidities not exceeding 65 % and at elevated temperatures with relative humidities above 80 %. NOTE 1If a sample shows sensitivity to thi
32、s test, it should also be tested for sensitivity to the tests specified in ISO 105-G01 (colour fastness to nitrogen oxides) and ISO 105-G02 (colour fastness to burnt-gas fumes). 2 Normative references The following standards contain provisions which, through reference in this text, constitute provis
33、ions 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 recent editions of the standards indicated be

35、:1985, Textiles Tests for colour fastness Part F: Standard adjacent fabrics. 3 Principle 3.1 A specimen and a swatch of test-control fabric are simultaneously exposed to ozone, in an atmosphere at ambient room temperature and a relative humidity not exceeding 65 %, until the test control shows a col
36、our change corresponding to that of a standard of fading. This exposure period constitutes one cycle. The cycles are repeated until the specimen shows a definite colour change or for a prescribed number of cycles. 3.2 A specimen and a swatch of test-control fabric are simultaneously exposed to ozone
37、 in an atmosphere which is maintained at (85 5) % relative humidity and a temperature of 40 C 5 C until the test control shows a colour change corresponding to that of a standard of fading. The cycle is repeated until the specimen shows a definite colour change or for a prescribed number of cycles.
38、NOTE 2The fading of dyes on certain fibres does not readily take place at humidities below 80 %. The test at high humidity is therefore required to produce a colour change that predicts service fading under warm, humid conditions. 4 Apparatus and materials 4.1 Ozone exposure chamber for ambient room
39、 temperatures and relative humidities not exceeding 65 % (see A.1). 4.2 Ozone exposure chamber for elevated temperatures and relative humidities above 80 % (see clause A.2). 4.3 Test-control fabric for relative humidities not exceeding 65 % (see Annex B). 4.4 Standard of fading for relative humiditi
40、es not exceeding 65 % (see Annex B). 4.5 Test-control fabric for high humidities (see Annex B). 4.6 Standard of fading for high humidity (see Annex B). 4.7 Grey scale for assessing change in colour, complying with ISO 105-A02. 5 Test specimens 5.1 If the textile to be tested is fabric, use a specime
41、n measuring 60 mm 100 mm. 5.2 If the textile to be tested is yarn, knit it into fabric and use a piece measuring 60 mm 100 mm or wind it closely round a piece of cardboard measuring 60 mm 100 mm to form a layer having only the thickness of the yarn. 5.3 If the textile to be tested is loose fibre, co
42、mb and compress enough of it to form a sheet measuring 60 mm 100 mm and sew the sheet on a piece of cotton adjacent fabric, complying with ISO 105-F, section F02, to support the fibre. 5.4 For subsequent colour comparison, the unexposed sample shall be kept in an airtight container away from light t
43、o avoid further shade change. 6 Procedure 6.1 At relative humidities not exceeding 65 % 6.1.1 Suspend each specimen and a swatch of the test-control fabric (4.3) in the exposure chamber (4.1) so that each piece hangs separately. The test shall be conducted with the chamber in a room in which the amb
44、ient air temperature is 18 C to 28 C and the relative humidity does not exceed 65 %. Ozone shall be present in concentrations which produce one cycle if fading in 1,5 h to 6 h of test.

45、05-G03:1997 2 BSI 09-1999 6.1.2 Compare the colour of the control swatch with that of the standard of fading (4.4) periodically in daylight ranging from average to slightly bluish North Sky light, or equivalent artificial light. When they match, the specimens have been exposed for one cycle and each
46、 shall then be compared with a specimen of the untreated material. 6.1.3 Remove those specimens which exhibit a colour change at the end of one cycle. One cycle will generally produce a measurable colour change in samples which are ozone-sensitive. 6.1.4 Suspend a fresh swatch of the test-control fa
47、bric and continue exposure of any remaining specimens for a second cycle. 6.1.5 Run additional similar cycles as necessary. 6.1.6 At the end of each cycle, immediately compare those specimens which are removed from the exposure chamber with the preserved original samples from which they were drawn.
48、6.1.7 Assess the change in colour of the specimens, after any specified number of cycles, with the grey scale (4.7). 6.2 At high relative humidity 6.2.1 Suspend each specimen and a piece of the test-control fabric (4.5) in the exposure chamber (4.2) which is maintained at (85 5) % relative humidity
49、and a temperature of 40 C 5 C. Ozone shall be present in concentrations ranging from 10 pphm to 35 pphm, which should produce one cycle of fading in 6 h to 24 h of test. 6.2.2 Compare the colour of the control swatch with that of the standard of fading (4.6) periodically in daylight ranging from average to slightly bluish North Sky light, or equivalent artificial light. When they match, the specimens have been exposed for one cycle and each shall then be compared with a specimen of the untreated material.
