BSEN 20105-C05:1993 National foreword This British Standard has been prepared under the direction of the Textiles and Clothing Standard Policy Committee. It is the English language version of EN 20105-C05:1992 Textiles Tests for colour fastness PartC05: Colour fastness to washing Test 5, published by the European Committee for Standardization (CEN) which is identical with ISO 105-C05:1989, published by the International Organization for Standardization (ISO). The technical content of this British Standard is identical with that of the corresponding method in BS1006:1990 Methods of test for colour fastness of textiles and leather. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the EN title page, pages 2 to 4, an inside back cover and a back cover.

EN 20105-C05:1992 1 Scope This part of ISO 105 specifies Test No.5 of a series of five washing tests that have been established to investigate the fastness to washing of coloured textiles and which between them cover the range of washing procedures from mild to severe. NOTE 1 This method is designed to determine the effect of washing only on the colour fastness of the textile. It is not intended to reflect the result of the comprehensive laundering procedure. 2 Normative references The following standards 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 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 105-A01:1989, Textiles Tests for colour fastness Part A01: General principles of testing. ISO 105-A02:1987, Textiles Tests for colour fastness Part A02: Grey scale for assessing change in colour. ISO 105-A03-1987, Textiles Tests for colour fastness Part A03: Grey scale for assessing staining. ISO 105-F:1985, Textiles Tests for colour fastness Part F: Standard adjacent fabrics. ISO 105-F10:1989, Textiles Tests for colour fastness Part F10: Specification for adjacent fabric: Multifibre. 3 Principle A specimen of the textile in contact with one or two specified adjacent fabrics is mechanically agitated under specified conditions of time and temperature in a soap solution, then rinsed and dried. The change in colour of the specimen and the staining of the adjacent fabric(s) are assessed with the grey scales. 4 Apparatus and reagents 4.1 Suitable mechanical device (see clause8), consisting of a water bath containing a rotatable shaft which supports, radially, glass or stainless-steel containers 75mm ± 5mm in diameter 125mm ± 10 mm high of550 ml ± 50ml capacity, the bottom of the containers being 45 mm ± 10 mm from the centre of the shaft. The shaft/container assembly is rotated at a frequency of 40min 1 ± 2min 1. The temperature of the water bath is thermostatically controlled to maintain the test solution at the prescribed temperature of95 C ± 2 C. 4.2 Non-corrodible (stainless) steel balls, approximately 6mm in diameter. 4.3 Soap, containing not more than 5% moisture and complying with the following requirements based upon dry mass: free alkali, calculated as Na 2 CO 3 :0,3% maximum; free alkali, calculated as NaOH:0,1% maximum; total fatty matter:850g/kg minimum; titre of mixed fatty acids prepared from soap: 30 C maximum; iodine value:50 maximum. The soap shall be free from fluorescent brightening agents. 4.4 Soap solution, containing 5g of soap (4.3) and 2g of anhydrous sodium carbonate per litre of water (4.7). 4.5 Adjacent fabrics (see ISO 105-A01:1989, sub-clause8.3). Either: 4.5.1 A multifibre adjacent fabric (TV) not containing wool or acetate, complying with ISO 105-F10. Or: 4.5.2 Two single-fibre adjacent fabrics, complying with the relevant sections of F02 to F05 of ISO 105-F:1985. One of the adjacent fabrics shall be made of the same kind of fibre as that of the textile to be tested, or that predominating in the case of blends, and the second piece made of the fibre as indicated in Table 1 or, in the case of blends, of the kind of fibre second in order of predominance, or as otherwise specified.

EN 20105-C05:1992 Table 1 Single-fibre adjacent fabrics cotton linen viscose polyamide polyester acrylic If first piece is: 4.5.3 If required, a non-dyeable fabric (for example, polypropylene). 4.6 Grey scale for assessing change in colour, complying with ISO 105-A02, and grey scale for assessing staining, complying with ISO 105-A03. 4.7 Grade 3 water (see ISO 105-A01:1989, sub-clause8.2). 5 Test specimen Second piece to be: viscose cotton or viscose cotton cotton or viscose cotton or viscose cotton or viscose 5.1 If the textile to be tested is fabric, either a) attach a specimen measuring 40mm 100 mm to a piece of the multifibre adjacent fabric, also measuring 40mm 100 mm, by sewing along one of the shorter sides, with the multifibre fabric next to the face of the specimen; or b) attach a specimen measuring 40mm 100 mm between the two single-fibre adjacent fabrics, also measuring 40mm 100 mm, by sewing along one of the shorter sides. 5.2 Where yarn or loose fibre is to be tested, take a mass of the yarn or loose fibre approximately equal to one-half of the combined mass of the adjacent fabrics (see below), and either a) place it between a40 mm 100mm piece of the multifibre adjacent fabric and a40mm 100 mm piece of the non-dyeable fabric and sew them along all four sides (see ISO 105-A01:1989, sub-clause9.6); or b) place it between a40 mm 100mm piece of each of the two specified single-fibre fabrics and sew along all four sides. 6 Procedure 6.1 Place the composite specimen in the container together with 10 non-corrodible (stainless) steel balls (4.2) and add the necessary amount of soap solution (4.4), previously heated to 95 C ± 2 C, to give a liquor ratio of50 :1. 6.2 Treat the composite specimen at 95 C ± 2 C for 4h. 6.3 Remove the composite specimen, rinse it twice in cold grade 3 water (4.7) and then in cold, running tap water for 10min, and squeeze it. Open out the composite specimen (by breaking the stitching except on one of the shorter sides, if necessary) and dry it by hanging it in air at a temperature not exceeding 60 C, with the two or three parts in contact only at the line of stitching. 6.4 Assess the change in colour of the specimen and the staining of the adjacent fabric(s) with the grey scales (4.6). 7 Test report The test report shall include the following particulars: a) the number and date of this part ofiso 105, i.e.iso 105-C05:1989; b) all details necessary for the identification of the sample tested; c) the numerical rating for change in colour of the specimen; d) if single-fibre adjacent fabrics were used, the numerical rating for staining of each kind of adjacent fabric used; e) if a multifibre adjacent fabric was used, the staining of each type of fibre in the multifibre adjacent fabric, and the type of multifibre adjacent fabric used. 8 Notes Other mechanical devices may be used for this test, provided that the results are identical with those obtained by the apparatus described in4.1. 4 BSI 08-1999
