20、 Reference number IS0 105-203:1996(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body

21、 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. IS0 collaborates closely with the International Electrote

22、chnical Commission (IEC) on all matters of electrotechnical standardization. Drat 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 vot

23、e. International Standard IS0 105-203 was prepared by Technical Committee ISOTTC 38, Textdes, Subcommittee SC 1, Tests for coloured textiles and colorants. IS0 105 was previously published in thirteen “parts”, each designated by a letter (e.g. “Part A), with publication dates between 1978 and 1985.

24、Each part contained a series of “sections”, each designated by the respective part letter and by a two-digit cena1 number (e.g. “Section A01”). These sections are now being republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric designations. A compl

25、ete list of these parts is given in IS0 105-A01.

27、erence ic ic rn The following standard contains provisions which, through reference in this text, constitute provisions of this pari of IS0 105. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part of IS0 105

28、 are encouraged to investigate the possi- bility of applying the most recent edition of the stan- dard indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards. IS0 3696:1987, Water fur analytical laboratory use - Specification and fest methods. 3 Princip

29、le In the dyeing of acrylic fibres with basic dyes, the classic parameters, e.g. the time of half-dyeing, of individual dyes do not give a true indication of their dyeing behaviour in admixture with other basic dyes. Since, under normal dyeing conditions, basic dyes show virtually no migration in ac

30、rylic fibres, compatibility is of major importance in selecting dye combinations with optimum, level, dyeing behaviour. Compatibility is assessed against one of two defined five-step scales: a yellow scale and a blue scale. The assessments are made using the scale showing the greatest difference in

31、hue from that of the dye under test. The compatibility value of the dye is assessed by de- termining its dyeing behaviour in combination with each of a series of reference dyes in the relevant scale. NOTE- The recommended reference dyes have been chosen because they form two series encompassing the

32、compatibility be- haviour of nearly all basic dyes recommended for wtyk fib res; the dyes in a series are spaced to produce approxi- mately equal visual effects; the corresponding reference dyes from both scales are compatible. Safety precautions NOTE - These safety precautions are for information p

33、ur- poses only. The precautions are ancillary to the test pro- cedures and are not intended to be ali-inclusive. it is the users responsibility to use safe and proper techniques in handling materials in this test method. Consult manufac- turers for specific details such as material safety data sheet

34、s and other recommendations. 4.1 Follow good laboratory practice. Wear safety glasses in all laboratory areas and a single-use dust respirator while handling powder dyes. 1 STD-BSI BS EN IS0 LOS-ZO3-ENGL 1798 w Lb24bb9 0707537 Lb Blue scale CI Basic Blue 69 CI Basic Blue 45 1 CI Basic Blue 47 200 %

NOTES 1 Acrylic fibres can vary widely in their dyeing character- istics. The test is conducted in such a manner that all avail- able dye is exhausted in approximately equal portions on to each of the five specimens used. In order to accomplish this, it may be necessary to adjust the dyeing temperature within the range 90 “C to 100 “C and/or the
