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 4.1 Suitable mechanical device (see clause 8), consisting of a water bath containing a rotatable shaft which supports, radially, glass or stainless-steel containers 75 mm ± mm in diameter × 125 mm ± 10 mm high of 550 ml ± 50 ml 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 40 min–1 ± min–1 The temperature of the water bath is thermostatically controlled to maintain the test solution at the prescribed temperature of 95 °C ± °C 4.2 Non-corrodible (stainless) steel balls, approximately mm in diameter 4.3 Soap, containing not more than % moisture and complying with the following requirements based upon dry mass: — free alkali, calculated as Na2CO3: 0,3 % maximum; — free alkali, calculated as NaOH: 0,1 % maximum; — total fatty matter: 850 g/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 g of soap (4.3) and g of anhydrous sodium carbonate per litre of water (4.7) 4.5 Adjacent fabrics (see ISO 105-A01:1989, sub-clause 8.3) 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 or, in the case of blends, of the kind of fibre second in order of predominance, or as otherwise specified NOTE 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 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 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

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 © BSI 08-1999 EN 20105-C05:1992 Table — Single-fibre adjacent fabrics If first piece is: cotton linen viscose polyamide polyester acrylic Second piece to be: viscose cotton or viscose cotton cotton or viscose cotton or viscose cotton or viscose 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 water (see ISO 105-A01:1989, sub-clause 8.2) Test specimen 5.1 If the textile to be tested is fabric, either a) attach a specimen measuring 40 mm × 100 mm to a piece of the multifibre adjacent fabric, also measuring 40 mm × 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 40 mm × 100 mm between the two single-fibre adjacent fabrics, also measuring 40 mm × 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 a 40 mm × 100 mm piece of the multifibre adjacent fabric and a 40 mm × 100 mm piece of the non-dyeable fabric and sew them along all four sides (see ISO 105-A01:1989, sub-clause 9.6); or b) place it between a 40 mm × 100 mm piece of each of the two specified single-fibre fabrics and sew along all four sides 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 ± °C, to give a liquor ratio of 50 : 6.2 Treat the composite specimen at 95 °C ± °C for h 6.3 Remove the composite specimen, rinse it twice in cold grade water (4.7) and then in cold, running tap water for 10 min, 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) Test report The test report shall include the following particulars: a) the number and date of this part of ISO 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 ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ Notes Other mechanical devices may be used
