This European Standard shall be given the status ofa National Standard, either by publication of an identical text or by endorsement, at the
19、latest by July1995, and conflicting national standards shall be withdrawn at the latest by July1995. According to the CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland

NOTENormative references to international publications are listed in Annex ZA (normative).EN20105-N01:1995 BSI 12-1999 3 1 Scope This part of ISO105 specifies a method for determining the resistance of th
21、e colour of textiles of all kinds and in all forms to the action of bleaching baths containing sodium or lithium hypochlorite in concentrations normally used in commercial bleaching. It is applicable mainly to natural and regenerated cellulose materials. 2 Normative references The following standard
22、s contain provisions which, through reference in this text, constitute provisions of this part of ISO105. 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 ISO105 are encouraged to investigate the pos
23、sibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

24、r fastness Part A02: Grey scale for assessing change in colour. ISO105-C01:1989, Textiles Tests for colour fastness Part C01: Colour fastness to washing:Test1. 3 Principle A specimen of the textile is agitated in a solution of sodium or lithium hypochlorite, rinsed in water, agitated in a hydrogen p
25、eroxide solution or sodium hydrogen sulfite solution, rinsed and dried. The change in colour is assessed with the grey scale. 4 Apparatus and reagents 4.1 Glass or glazed-porcelain container, which can be closed, for specimen and bleaching solution. 4.2 Hypochlorite solutions Use one of the two solu
26、tions specified in4.2.1 and4.2.2. 4.2.1 Sodium hypochlorite (NaOCl) solution, containing approximately2g of available chlorine per litre, buffered at pH11 0,2 with10g of anhydrous sodium carbonate (Na 2 CO 3 ) per litre, at a temperature of20 C 2 C. To prepare this reagent, use commercially availabl
27、e sodium hypochlorite solution. This has the following composition: active chlorine:140g/l to160g/l; sodium chloride: (NaCl):120g/l to170g/l; sodium hydroxide: (NaOH):20g/l maximum; sodium carbonate (Na 2 CO 3 ):20g/l maximum; iron (Fe):0,01g/l maximum. Dilute20,0ml of the commercially available sod
28、ium hypochlorite solution to1 litre with grade3 water(4.6). To25ml of this solution add excess potassium iodide (KI) and hydrochloric acid (HCl) and titrate the liberated iodine with a sodium thiosulfate solution, c(Na 2 S 2 O 3 )=0,1mol/l, using starch as indicator. Let the volume of sodium thiosul
29、fate solution required be V ml. For each litre of working solution at pH11 0,2 use 14100/Vml of the diluted sodium hypochlorite solution; 10g of anhydrous sodium carbonate. Dilute to1litre. All sodium hypochlorite solutions should be prepared just prior to use. 4.2.2 Lithium hypochlorite (LiOCl) sol
30、ution, containing approximately2g of available chlorine per litre, buffered at pH11 0,2 with10g of anydrous sodium carbonate (Na 2 CO 3 ) per litre, at a temperature of20 C 2 C. To prepare this reagent, use solid lithium hypochlorite, which contains approximately300g of LiOCl per kilogram. About10g
31、of solid lithium hypochlorite dissolved in1litre of grade3 water(4.6) yields a solution of the prescribed concentration of approximately2g of available chlorine per litre. Prepare the lithium hypochlorite solution as described in4.2.1 for sodium hypochlorite. 4.3 Hydrogenperoxide solution, containin
32、g2,5mlofhydrogen peroxide 30% (m/m) H 2 O 2 per litre, or a solution containing5g of sodium hydrogen sulfite (NaHSO 3 ) per litre. WARNING Attention is drawn to the need for relevant safety precautions when using hydrogen peroxide. 4.4 Soap solution, containing5g of soap per litre (seeISO105-C01:198
33、9, subclause4.3), for wetting out water-repellent fabrics. 4.5 Grey scale for assessing change in colour, complying with ISO105-A02. 4.6 Grade3 water (seeISO105-A01:1989, subclause8.2). 5 Test specimen 5.1 If the textile to be tested is fabric, use a specimen measuring40mm 100mm.EN20105-N01:1995 4 B
34、SI 12-1999 5.2 If the textile to be tested is yarn, knit it into fabric and use a piece measuring40mm 100mm, or wind it closely round a piece of thin, inert material measuring40mm 100mm to form a layer having the thickness of only one yarn. 5.3 If the textile to be tested is loose fibre, comb and co
35、mpress enough of it to form a sheet measuring40mm 100mm; in order to support the fibres, sew the sheet on a piece of fabric which will not affect the action of the hypochlorite on the specimen. 6 Procedure 6.1 If the textile to be tested has a water-repellent finish, wet out the specimen thoroughly
36、in the soap solution(4.4) at25 C to30 C. Drain the specimen of excess liquor so that it retains approximately its dry mass of wetting-out solution, and immediately place the specimen, opened out, in the sodium or lithium hypochlorite solution (4.2) at20 C 2 C at a liquor ratio of50:1. 6.2 If the tex
37、tile to be tested has no water-repellent finish, wet out the specimen in grade3 water (4.6) at room temperature, remove the excess water (see6.1) and place the test specimen, opened out, in the sodium or lithium hypochlorite solution (4.2) at20 C 2 C at a liquor ratio of50:1. 6.3 Close the container
38、 and allow the specimen to stand in the solution at20 C 2 C for60min. Avoid exposure to direct sunlight. 6.4 Rinse the specimen thoroughly in cold, running tap-water, and then agitate it at room temperature for10min in one of the solutions specified in4.3. 6.5 Rinse the specimen thoroughly in cold,
39、running tap-water, remove the excess water and dry the specimen by hanging it in air at a temperature not exceeding60 C. 6.6 Assess the change in colour of the specimen with the grey scale (4.5). 7 Test report The test report shall include the following particulars: a) the number and date of publica
40、tion of this part of ISO105, i.e.ISO105-N01:1993; b) all details necessary for the identification of the sample tested; c) the numerical rating for the change in colour of the specimen.EN20105-N01:1995 BSI 12-1999 5 Annex ZA (normative) Normative references to international publications with their r
