Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European

21、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 right to be represented on that committee. International organizat
22、ions, 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 International Standards adopted by the technical committees are circul
23、ated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote.

24、s. 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 “sections”, each designated by the respective part letter and by a two-digit serial number (e.g. “Section A01”). These s
25、ections 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 ISO 105-A01. Annex A of this part of ISO 105 is for information only. Descriptors: Textiles, dyeing, colour fastnes

The method is not intended to m

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 this text, constitute provisions of this part of ISO 105. At the time of publication, the editions i
28、ndicated 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 of the standards indicated below.

30、 of the dye to be tested are prepared at25C. The solutions are then filtered under suction at this temperature in a heatable Nutsch filter and the cold water solubility limit determined by visual assessment of the filter residues and the measured flow-through time of the filtrate. 4 Apparatus and re

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 listed in the test report. 4.
35、8 Water, complying with grade 3 of ISO 3696, used as dye solvent. An amount of200ml is designated as normal. More water may be added to the solution, but such additions shall be reported together with the cold water solubility values. NOTE 3No account is taken of changes in volume caused by the addi
36、tion of dye. 5 Preparation of solutions 5.1 The concentrations at which the dye solutions are prepared shall be chosen considering the expected cold water solubility limit of the dye: Property Two typical sets of values Grammage, g/m 2 92 121 Thickness, m 210 330 Air resistance, Gurley, s/100ml 3,6

38、of the test dye into a glass beaker (4.1) containing200ml water under agitation (4.8) at25C 2 C (maximum strewing time5s) in the thermostatically controlled heating bath (4.2). Continue stirring for a maximum total stirring time of 2 min or 5 min. Filter the solution immediately (see clause 6). Stir
39、ring time shall be indicated in the test report along with cold water solubility limit. Repeat the process for each concentration of dye under test. 6 Filtering the solutions NOTE 4In order to avoid any temperature shock effects, it is essential that heated solutions are filtered through equipment a
40、lready 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
41、 the equipment immediately prior to carrying out the test. When using this latter technique, the amount of water should be determined locally in order that the filter funnel can be heated to the same temperature irrespective of its geometry and the ambient conditions. In all cases when using preheat
42、ing techniques rather than a jacketed funnel, the test solution should be passed through the test equipment immediately after removing it from its heating medium. 6.1 Bring the Nutsch filter (4.3) to the dissolving temperature of25C (see 4.4) and maintain this temperature during the entire filtratio
43、n operation. 6.2 Immediately before filtering, wet out two filter papers (4.7) in a double layer with at least50ml water at25C in the Nutsch filter. 6.3 Adjust the vacuum (4.5) to between3kPa to4kPa, which is equivalent to300mm to400mm water column pressure. 6.4 Filter the dye solution (5.2) at25C 2
44、 C and measure the flow-through time with the stopwatch(4.6). 6.5 If the solution does not filter within 2 min at a stabilized vacuum, filter it for an additional maximum 2 min under full vacuum (see 4.5.2). 6.6 After the solution has flowed through, continue to extract the filter uniformly under fu
45、ll vacuum for1min. 6.7 Allow the filters to dry completely at room temperature before evaluation. 7 Evaluation 7.1 Compare visually the dried filters after filtration of the various dye solutions of known concentrations. The cold water solubility limit is taken as that concentration at which filter
46、residues are seen. Residues that are difficult to see may possibly be detected by gently rubbing the filter surface with a fingertip. 7.2 Flow-through time may be used as a further evaluation criterion. A sudden sharp increase in flow-through time when moving up the range of solution concentrations
47、indicates that the cold water solubility limit has been exceeded. 8 Test report The test report shall include the following information: a) number and year of publication of this part of ISO 105, i.e. ISO 105-Z09:1995; b) full identification of the dyestuff under test; c) type of filter paper used a
48、nd its manufacturer; d) stirring time (2min or5min) used in preparation of dyestuff solutions (see 5.2); e) cold water (25C) solubility limit of the dyestuff, expressed in grams per litre; f) flow-through time, where applicable (see 7.2); g) any special observations during the test or evaluation pro

However, it should be pointed out that test conditions which deviate from those specified may lead to quite different results. For example, the results may be influenced when: a) A different filter is used. The filter selected for the test should re
