21、es). The work of preparing International Standards is normally carried out through IS0 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 and

22、nongovernmental, in liaison with ISO, also take part in the work. IS0 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 bodie

23、s for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 105209 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. IS0 105 was previous

24、ly 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 re- spective part letter and by a twodigit serial number (e.g. “Section A01 “). These sections are now being

25、 republished as separate documents, them- selves designated “parts“ but retaining their earlier alphanumeric desig- nations. A complete list of these parts is given in IS0 105AO1.

39、er (4.1) containing 200 ml water under agi- tation (4.8) at 25 OC * 2 “C (maximum strewing time 5 s) 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). Stirring time shall be in

40、dicated in the test report along with cold water solubility limit. Repeat the process for each concentration of dye un- der test. 6 Filtering the solutions NOTE 4 In order to avoid any temperature shock effects, it is essential that heated solutions are filtered through equipment already brought to

41、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 imm

42、ediately 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 ir- respective of its geometry and the ambient conditions. In all cases when using preheating techniques r

43、ather 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 of 25 “C (see 4.4) and maintain this temperature during the entire filtration operation.

44、6.2 Immediately before filtering, wet out two filter papers (4.7) in a double layer with at least 50 ml water at 25 OC in the Nutsch filter. 6.3 Adjust the vacuum (4.5) to between 3 kPa to 4 kPa, which is equivalent to 300 mm to 400 mm water column pressure. 6.4 Filter the dye solution (5.2) at 25 O

45、C f 2 OC 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). 2 STDSBSI BS EN IS0 LOS-ZOS-ENGL L778 LbZibbS b72588 7b5 Bs EN IS0 105-209 : 1998 6.6

46、 After the solution has flowed through, continue to extract the filter uniformly under full vacuum for 1 min. 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 conc

47、entrations. The cold water solubility limit is taken as that con- centration at which filter 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 su

48、dden sharp increase in flow- through time when moving up the range of solution concentrations indicates that the cold water solubility limit has been exceeded. 8 Test report The test report shall include the following information: number and year of publication of this part of IS0 105, .e.
