18、164-1987), developed by AATCC in response to a specific need in the USA for the determination of fading in the presence of nitrogen oxide at high relative humidities. Such conditions are prevalent along the Gulf of Mexico coast of the USA and in Southern California. Fading of some dyes on certain ma
19、n-made fibres, particularly on carpets, was observed to be quite severe under such conditions. The development of this test method enabled dye manufacturers, fibre producers and textile manufacturers to select dye/fibre combinations which were resistant to fading in the presence of nitrogen oxide at
20、 high relative humidities. The same fabrics, when tested at low humidities, showed little or no fading.

25、a colour change-corresponding to that of a standard of fading.The exposure/measurement cycle is repeated until the test specimen shows a definite colour change or for a prescribed number of cycles.4 Apparatus and reagents4.1 Exposure chamber, see Annex A.4.2 Test-control fabric4.2.1 Test-control fab

31、atch an average of faded test-control fabric.3)4.3.2 Standard of fading for test-control fabric dyed with Disperse Blue 56It is considered that the standard of fading is completed when a faded test-control fabric (4.2.2) is observed to have a contrast equal to grade 3-4 on the in grey scale.4.4 Grey
32、 scale for assessing change in colour, complying with ISO 105-A02.4.5 Nitrogen oxideUse bottled gas which contains approximately 1 % nitrogen dioxide in nitrogen, in cylinders equipped with the proper reducing valves. For safety, chain the cylinders to a wall so that they cannot fall or be knocked d
33、own.WARNING Nitrogen oxide in high concentrations are injurious to health and should be exhausted to the atmosphere or trapped in water and neutralized with a 10 % (m/m) solution of sodium hydroxide or sodium hydrogen carbonate. The maximum concentration in a work area should not exceed 9,57 mg/m3.4
34、.6 Urea after treatmentThe use of this treatment is optional.Experience has shown that colour change after removal of test specimens from the exposure chamber is negligible. The urea treatment itself will often cause a colour change in test specimens. Therefore, if 1) Test-control fabric dyed with D

38、CONH2), buffered to pH 7 by the addition of 0,4 g/l of sodium dihydrogen orthophosphate dehydrate (NaH2PO42H2O), and 2,5 g/l of disodium hydrogen orthophosphate dodecahydrate (Na2HPO412H2O), and containing 0,1 g/l or less of a rapid-wetting surface-active agent; for example, sodium dioctyl sulfosucc
39、inate.5 ConditioningThe standard temperate atmosphere for testing textiles (see ISO 139), i.e. a relative humidity of (65 4) % and temperature of (20 2) C, shall be used for conditioning.6 Test specimensCut out test specimens measuring at least 60 mm 60 mm. For subsequent colour comparison, the unex
40、posed sample shall be kept in an airtight container away from light to avoid further colour changesIf the test involves the effect of nitrogen oxide on laundered or dry-cleaned material, use laundered or dry-cleaned material for both the control and test exposure. For the preparation of test specime
41、ns for testing after laundering or dry cleaning, follow the procedures described in ISO 105-C10 and/or ISO 105-D01. While laundering or dry-cleaning before testing, the size of the test specimens also meets at least 60 mm 60 mm.7 Procedure7.1 Suspend the test specimens and piece of test-control fabr
42、ic (4.2.1 or 4.2.2) in the exposure chamber (4.1) which should produce a cycle of fade within 5 h to 15 h of exposure.7.2 Examine the test-control fabric periodically until its colour corresponds to that of the standard of fading. This constitutes one cycle. An alternative method of determining one
43、cycle of fade is to terminate the exposure cycle when the test-control fabric exhibits a colour change of (16,5 1,5) CIELAB units (see ISO 105-J01).7.3 Remove those test specimens which exhibit a noticeable colour change at the end of one cycle. One cycle will generally produce a measurable colour c
44、hange in samples which are sensitive to nitrogen oxide.7.4 Suspend a fresh piece of test-control fabric (4.2.1 or 4.2.2) for each additional cycle of fade until the required number of cycles has been completed.Test specimens exposed to nitrogen oxide may continue to change colour after removal from
45、the test chamber. The colour may be stabilized by plunging them into a buffered urea solution (see 4.6) for 5 min, squeezing them out, thoroughly rinsing them in clean water and drying them in air at a temperature not above 60 C. Do not treat with the urea solution any test specimen that is to be re
46、turned to the test chamber for additional exposure.7.5 At the end of each cycle, immediately assess the change in colour of the test specimen using the grey scale for assessing change in colour (4.4).7.6 Classify the effect on colour of test specimens after the specified number of cycles, using the
47、grey scale for assessing change in colour (4.4).

49、9 Notes on humidity for testingThe fading of dyes by nitrogen oxide on some fibres, such as polyamide and acetate, is altered greatly by relatively small variations in relative humidity at high humidities. Therefore, to achieve reproducibility and good interlaboratory correlation in test results, close control of temperature and relative humidity is required.4 ISO 2016 All rights reservedBS ISO 105-G04:2016ISO 105-G04:2016(E)Annex A (normative) Test apparatusSuitable test apparatus is shown in Figu
