21、tandardization) is a worldwide 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 ri

22、ght 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft Intern

23、ational 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 a vote. International Standard ISO 105-G03 was prepared by Technical Committee ISO/TC38, Textil

24、es, Sub-Committee SC1, Tests for coloured textiles and colorants. This second edition cancels and replaces the first edition (included in ISO105-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

25、publication dates between1978 and1985. 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

26、rlier alphanumeric designations. A complete list of these parts is given in ISO105-A01. Annex A and Annex B form an integral part of this part of ISO105. Annex C is for information only.

27、blankENISO105-G03:1997 BSI 09-1999 1 1 Scope This part of ISO 105 specifies a method for determining 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 exceeding65% and at ele

28、vated temperatures with relative humidities above80%. NOTE 1If a sample shows sensitivity to this test, it should also be tested for sensitivity to the tests specified in ISO105-G01 (colour fastness to nitrogen oxides) and ISO105-G02 (colour fastness to burnt-gas fumes). 2 Normative references The f

29、ollowing standards contain provisions which, through reference in this text, constitute provisions of this part of ISO105. 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 ISO105 are encouraged to in

30、vestigate 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-F: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 roo

32、m temperature and a relative humidity not exceeding65%, until the test control shows a colour 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 cycl

33、es. 3.2 A specimen and a swatch of test-control fabric are simultaneously exposed to ozone in an atmosphere which is maintained at (85 5)% relative humidity and a temperature of40 C 5 C until the test control shows a colour change corresponding to that of a standard of fading. The cycle is repeated

34、until the specimen shows a definite colour change or for a prescribed number of cycles. NOTE 2The fading of dyes on certain fibres does not readily take place at humidities below80%. The test at high humidity is therefore required to produce a colour change that predicts service fading under warm, h

35、umid conditions. 4 Apparatus and materials 4.1 Ozone exposure chamber for ambient room temperatures and relative humidities not exceeding65% (see A.1). 4.2 Ozone exposure chamber for elevated temperatures and relative humidities above80% (see clauseA.2). 4.3 Test-control fabric for relative humiditi

36、es not exceeding65% (see Annex B). 4.4 Standard of fading for relative humidities not exceeding65% (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 ISO105-A0

37、2. 5 Test specimens 5.1 If the textile to be tested is fabric, use a specimen measuring60mm 100mm. 5.2 If the textile to be tested is yarn, knit it into fabric and use a piece measuring60mm100mm or wind it closely round a piece of cardboard measuring60mm 100mm to form a layer having only the thickne

38、ss of the yarn. 5.3 If the textile to be tested is loose fibre, comb and compress enough of it to form a sheet measuring60mm 100mm and sew the sheet on a piece of cotton adjacent fabric, complying with ISO105-F, sectionF02, to support the fibre. 5.4 For subsequent colour comparison, the unexposed sa

39、mple shall be kept in an airtight container away from light to 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 sh

40、all be conducted with the chamber in a room in which the ambient air temperature is18 C to28 C and the relative humidity does not exceed65%. Ozone shall be present in concentrations which produce one cycle if fading in1,5h to6h of test.ENISO105-G03:1997 2 BSI 09-1999 6.1.2 Compare the colour of the

41、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 shall then be compared with a specimen of the untreated m

42、aterial. 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 fabric and continue exposure of any remaining specimens for

43、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. 6.1.7 Assess the change in colour of the specimens, after

44、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 and a temperature of40 C 5 C. Ozone shall be present in conc

45、entrations ranging from10pphm to35pphm, which should produce one cycle of fading in6h to24h 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 lig

46、ht. When they match, the specimens have been exposed for one cycle and each shall then be compared with a specimen of the untreated material. 6.2.3 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 whi

47、ch are ozone-sensitive. 6.2.4 Suspend a fresh swatch of the control sample and continue exposure of any remaining specimens for a second cycle. 6.2.5 Run additional similar cycles as necessary. 6.2.6 At the end of each cycle, immediately compare those specimens which are removed from the exposure ch

48、amber with the preserved original samples from which they were drawn. 6.2.7 Assess the change in colour of the specimens, after any specified number of cycles, with the grey scale (4.7). 7 Test report The test report shall include the following particulars: a) the number and date of publication of t

49、his part of ISO105, i.e. ISO105-G03:1993; b) all details necessary for the identification of the sample tested; c) the numerical rating for the change in colour of each specimen; d) the number of cycles run and the temperature and relative humidity at which the test was performed.ENISO105-G03:1997 BSI 09-1999 3 Annex A (normative) Ozone exposure chambers A.1 The ozone exposure chamber for ambient room temperatures and relative humidities not exceeding65% consists of an ozone generator, fan, baffle system,
