20、 Table 1 Selection of applicable test 2ENISO105-Z04:1997 ii BSI 05-1999 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 tech
21、nical 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 closely
22、 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% o
23、f the member bodies casting a vote. International Standard ISO105-Z04 was prepared by Technical Committee ISO/TC38, 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 publicat
24、ion 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 earlier a
25、lphanumeric designations. A complete list of these parts is given in ISO105-A01. Descriptors: Textiles, dyeing, colour fastness, dyes, tests, colour-fastness tests, determination, dispersibility.ENISO105-Z04:1997 BSI 05-1999 1 1 Scope This part of ISO105 describes a method for determining the disper
26、sibility, as evaluated by filtering time and filter residue, of disperse dyes. This test method is used for determining the degree of dispersion under specified conditions in aqueous media only. NOTE 1The results of this test method can vary widely unless all tests are run under exactly the conditio
27、ns outlined. Any variation in the conditions can cause a test to be invalid. Results have been shown to be reproducible in several laboratories when the specified conditions are met. NOTE 2Variations in results can be caused by differences in the diameter of the filter funnel, due to the differences
28、 in surface area which result, and to variations in the size and density of the holes in the filter funnel. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this part of ISO105. At the time of publication, the edition in
29、dicated was valid. All standards are subject to revision and parties to agreements based on this part of ISO105 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid Internationa
30、l Standards. ISO 3696:1987, Water for analytical laboratory use. 3 Definition For the purposes of this part of ISO 105, the following definition applies. 3.1 dispersibility degree to which particles can be broken down to some minimum size such that they will pass through the interstices of a referen
31、ce filter paper 4 Principle A quantity of disperse dye is predispersed, heated and passed through filter papers of specified pore size. Using the time of passage and retention of dye on the filter paper, the dispersibility of the dye is then evaluated. Three variants of the test, depending on the in
32、tended dye application, are outlined. 5 Safety precautions 5.1 It is the users responsibility to use safe and proper techniques in handling materials in this test method. Consult manufacturers for specific details such as material safety data sheets and other recommendations. 5.2 Good laboratory pra
33、ctice should be followed. Wear safety glasses in all laboratory areas and a single-use dust respirator while handling powder dyes. 5.3 Users should comply with any national and local safety regulations. 6 Apparatus and materials During the test, use only reagents of recognized analytical grade and o
34、nly grade 3 water as defined in ISO3696. 6.1 Nutsch filter (Bchner funnel), of glass, stainless steel or porcelain, with inner diameter 110 mm, 192 holes and with a total surface area of holes (evenly distributed) of not less than 200 mm 2 . 6.2 Filter papers 1) , of diameter 110 mm, as follows. Typ

Such addition shall be mentioned in the test report. 6.14 Stirrer, laboratory, magnetic. 6.15 Graduated cylinder, 250ml capacity
41、. 6.16 pH-meter. 7 Procedure 7.1 Selection of test Select the test (I, II or III) to be used according to the intended application of the dye (see Table 1). Table 1 Selection of applicable test 7.2 Preparation of dispersion Using the analytical balance (6.9), weigh out2,0g 0,1g of dye powder, to be
42、tested. Weigh out an equivalent quantity of the manufacturers reference dye, and carry out the same test on this dye. The reference dye is always run as a control so that the influence of any test variables on the results is minimized. If required, on dyes of high tinctorial strength, reduce the dye
43、 concentration to1g/200ml and report this fact in the test report. Add the weighed dye slowly to200ml of vigorously agitated water (6.13) at 45C 2 C in a400ml beaker(6.8). Use a magnetic stirrer (6.14). Adjust the pH with the pH-meter (6.16) as follows: for Tests I and II: pH 4,5 to pH 5,0 using ace
44、tic acid (6.11); for Test III: pH 9,0 to pH 10,0 using TSPP(6.10). Heat to 70C 2C and hold at this temperature for 5min 1min. Stir with the magnetic stirrer to prevent localized heating. NOTE 3Excessive time lags and holding temperatures may affect the outcome of the test. Optionally, disperse and s
45、tir the dye at 25C 2C. In this case, no preheating of the Bchner funnel (see 7.3) is necessary. If this option is used, it shall be stated in the test report. 7.3 Filtration of dispersion Heat 100ml to 300ml of water to 70C and pour into the Bchner funnel (6.1) without any filter paper in place, to
46、preheat the funnel. Wait 25 s 10 s. Turn the vacuum on (6.4 to 6.6) and keep on until the water has passed through the funnel. Turn the vacuum off, immediately dry the funnel and then place the correct filter papers(6.2) in the funnel (see Table 1). Two filter papers are used to give a more uniform
47、vacuum across the filtering surface. The filter paper is used as received in the box, with the smooth side up to avoid variations due to texture differences on the rough side. If different types of filter paper are used, the coarser paper shall be underneath. Insert the stainless steel ring (6.3) in
48、 the funnel on top of the filter papers, and turn on the vacuum. Adjust the vacuum to 3 kPa to 4 kPa, which is equivalent to a300mm to400mm water column under pressure. NOTE 4Since filter paper is cellulosic in nature, it swells readily when wet. Therefore, if the paper is prewetted to hold it in pl
49、ace in the funnel, the filtration time will be increased, this increase depending on the temperature of the wet filter paper and the time which has been allowed to elapse since wetting. Thus it is imperative that the filter paper is not wet prior to the test, since the microretention characteristics of the paper will be reduced. This is the reason for using the stainless steel ring, which holds the filter paper in place, making prewetting unnecessary. With dyes which have a very small particle size, the speed o
