24、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 that committee. International organizations, governmental
25、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 by the technical committees are circulated to the member
26、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-Z07 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. ISO 105 was pr

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 b

30、luble dyes in the range 40 C to 90 C and of their solution stability. The method is not intended to measure absolute solubility. NOTE 1Several factors which may influence test results are listed in Annex A. 2 Normative references The following standards contain provisions which, through reference in
31、 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 recent editions
32、of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 1773:1976, Laboratory glassware Boiling flasks (narrow-necked). ISO 3696:1987, Water for analytical laboratory use Specification and test methods. 3 Principle Several solutions
33、 of known concentration, including the solubility limit, of the dye to be tested are prepared at a specified temperature. The solutions are then filtered under suction at this temperature in a heatable Nutsch filter and the application solubility limit determined by visual assessment of the filter r
34、esidues and the measured flow-through time of the filtrate. The application solubility of dyes is normally determined at 90 C. For certain classes of dyes the solubility is determined at a lower temperature. In selecting the test temperature, the manufacturers recommendations are followed. The tempe
35、rature is indicated in the test report (e.g. application solubility limit determined at 90 C, 60 C, etc.). The solution stability of dyes is determined by storing for 2 h and, as the case requires, cooling the above-mentioned solution before filtration and assessment. The dissolving and storage temp
36、eratures are indicated in the test report (e.g. solution stability at 90 C/60 C, 60 C/60 C, etc.). 4 Apparatus and reagents 4.1 Erlenmeyer flask, wide-mouthed, capacity 500 ml, complying with ISO 1773. 4.2 Heating bath, thermostatically controlled, with magnetic stirring bar 40 mm long by 6 mm diame
37、ter, speed of stirrer 500 r/min to 600 r/min. 4.3 Water bath, with temperature regulator (heating/cooling) for adjusting the storage temperature (e.g. 60 C, 30 C or 25 C). 4.4 Nutsch filter (Bchner funnel), heatable, of glass, steel or porcelain, of inner diameter 70 mm, capacity at least 200 ml, ha
38、ving more than 100 holes with a total surface area of holes (evenly distributed) of not less than 200 mm2. 4.5 Thermostatic device (optional), with circulation pump to adjust temperature of Nutsch filter. 4.6 Vacuum apparatus 4.6.1 Suction bottle, capacity 1 litre to 2 litres. 4.6.2 Piston or membra
39、ne pump, of sufficiently high suction capacity to create a full vacuum of at least 50 kPa under pressure. 4.6.3 Apparatus to adjust and maintain a given vacuum, preferably coupled with a manometer. 4.7 Stopwatch, to measure flow-through time. 4.8 Filter paper, circular, 70 mm 2 mm diameter.

42、grade 3 of ISO 3696, used as dye solvent. An amount of 200 ml is designated as normal. More water may be added to the solution, but such additions shall be reported together with the dye solubility values. NOTE 3No account is taken of changes in volume as a function of temperature, or those caused b
43、y the addition of dye. 5 Preparation of solutions 5.1 The concentrations at which the dye solutions are prepared shall be chosen considering the expected application solubility limit of the dye: 5.2 To determine solubility at 90 C, paste a known amount of the test dye and introduce it into the wide-
44、mouthed Erlenmeyer flask (4.1) with a portion of the 200 ml water (4.9) at about 60 C, but not in excess of the dissolving temperature of the dye. When the dye is completely wetted out, add the rest of the water to the flask. Place this solution into the heating bath (4.2) maintained at 95 C. Switch
45、 on the magnetic stirrer. When the solution has attained a temperature of 95 C 2 C, continue stirring at this temperature for a further 5 min (total stirring time approximately 10 min). Then filter the solution (see clause 6) immediately to determine the solubility of the dye at 90 C. Repeat the pro
46、cess for each concentration of dye under test. 5.3 To determine solubility at temperatures below 90 C, paste a known graduated amount of the test dye and introduce it into a wide-mouthed Erlenmeyer flask with a portion of the 200 ml water (4.9) at the desired dissolving temperature until the dye is
47、completely wetted out. Then add the rest of the water to the flask. Place the solution in the heating bath maintained at the desired dissolving temperature; stir the solution for 10 min and then filter (see clause 6). Repeat the process for each concentration of dye under test. 5.4 To determine the
48、solution stability at the desired temperature (e.g. 60 C, 30 C or 25 C), place the Erlenmeyer flask with the solution prepared according to 5.1 or 5.2 into a bath maintained at the desired temperature (see 4.3) and allow to stand for 2 h before filtration. Before filtering, mix the solution thorough
49、ly by tilting the flask to and fro. 6 Filtering the solutions NOTE 4In order to avoid any temperature shock effects, it is essential that heated solutions are filtered through equipment already brought to the same temperature as the solution under test. Ideally this is best done using a jacketed filter funnel, but acceptable results can also be obtained using preheated funnels, either by immersion in a water bath or oven, or by passing water preheated to the test temperature through the equipment immediate
