24、oreword 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 technical committees. Each member body interested in a subject for which a te
25、chnical 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 with the International Electrotechnical Commission (IEC) on all matters
26、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 % of the member bodies casting a vote. International Standard ISO 105-Z08 w
27、as prepared by Technical Committee ISO/TC 38, 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 publication dates between 1978 and 1985. Each part contained a series of “sect
28、ions”, 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 designations. A complete list of these parts is given in

30、08:1998 BSI 04-19991 1 Scope This part of ISO 105 describes a method for the determination of the solubility and the solution stability of reactive dyes for use in batchwise and continuous dyeing processes in the presence of electrolytes. NOTE 1Several factors which may influence test results are li
31、sted in Annex A. 2 Normative references The following standards contain provisions which, through reference in 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 bas
32、ed on this part of ISO 105 are encouraged to investigate 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 1773:1976, Laboratory glassware Boiling flasks (narrow-necked). IS
33、O 3696:1987, Water for analytical laboratory use Specification and test methods. 3 Principle Several solutions of known concentration, including the solution stability limit, of the dye to be tested are prepared at a specified temperature in accordance with the dye manufacturers recommendation. The
34、dye solution is adjusted to the desired test temperature. A specified amount of the desired electrolyte solution is added and the resultant solution either filtered immediately or stored for a specified time at a specified temperature and subsequently filtered under suction. The solubility and/or so
35、lution stability limits of the dye solution to the addition of electrolyte are determined by visual assessment of the filter residues and the measured flow-through time of the filtrate. 4 Apparatus and reagents 4.1 Erlenmeyer flask, wide-mouthed, capacity 500 ml, complying with ISO 1773. 4.2 Heating
36、 bath, thermostatically controlled, with magnetic stirring bar 40 mm long by 6 mm diameter, speed of stirrer 500 r/min to 600 r/min. 4.3 Water bath, with temperature regulator (heating/cooling) for adjusting the storage temperature. 4.4 Nutsch filter (Bchner funnel), heatable, of glass, steel or por
37、celain, of inner diameter 70 mm, capacity at least 200 ml, having 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 Suctio
38、n bottle, capacity 1 litre to 2 litres. 4.6.2 Piston or membrane 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 t
39、ime. 4.8 Filter paper, circular, 70 mm 2 mm diameter. NOTE 2Filter papers of the following characteristics have been found suitable: See ISO 105-A01:1994, clause 8, note 1 for information on sources of supply of suitable filter paper. The type of filter paper used and the manufacturer shall be liste
40、d in the test report. 4.9 Water, complying with grade 3 of ISO 3696 (recommended pH 7), used as solvent. 4.10 Electrolyte solution (stock solution), prepared using grade 3 water (4.9) according to the concentrations given in Table 1 or such that the required quantity of the desired electrolyte is co
41、ntained in 50 ml of solution. NOTE 3The reproducibility of the test method depends on the quality of the electrolyte. For this reason, chemically pure substances should be used. NOTE 4Although the electrolytes used are mostly simple salts, tests of the stability of their solutions, which need to be
42、carried out rapidly, often prove not very meaningful. Electrolyte solutions should therefore be discarded at the latest one week after their preparation.

44、nd its concentration, will depend on the type of dyestuff being tested. Examples of combinations of test parameters are given in Table 1. 6 Preparation of solutions 6.1 The concentrations at which the test dye solutions are prepared shall be chosen considering the expected solution stability limit o
45、f the dye in the presence of electrolyte: The maximum dye concentrations used for the test shall be: 30 g/l for batchwise dyeing processes; 100 g/l for continuous dyeing processes. 6.2 Place a known amount of the dye to be tested in the wide-mouthed Erlenmeyer flask (4.1) and add 150 ml water (4.9)
46、at about 60 C (but not above the dissolving temperature). Swirl the flask by hand until the dye is fully wetted out (predissolving). If the addition of urea is required as a dissolving agent in accordance with the recommendations of the dye manufacturer, reduce the amount of water by 1 ml per gram o
47、f urea added, so as not to change the total volume of the test solution. Place the solution into the heating bath (4.2), set at the desired dissolving temperature and stir for 10 min at 500 r/min to 600 r/min. 6.3 In order to simulate dyebath compositions used in commercial practice, additions of ot
48、her components to the test solution at this point are permissible (see dye manufacturers recommendations). Any such additions, including their influence on the volume of test solution, shall be noted in the test report. NOTE 5Changes in volume attributable to changes in temperature need not be taken
49、 into account. 6.4 Adjust the dye solution to the desired temperature for filtration or storage using the water bath (4.3), add 50 ml of the electrolyte solution (4.10) previously adjusted to the test temperature, and homogenize the resulting solution. 7 Storage Allow the final test solution to stand at constant temperature for the specified storage time (see Table 1). 8 Filtering the solutions NOTE 6In order to avoid any temperature shock effects, it is essential that heated solutions are filtered through equipment already br
