16、Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the r
17、ight to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Internation
18、al Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as
19、 an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. IS
20、O 105-C12 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. ISO 105 was previously published in thirteen “parts”, each designated by a letter (e.g., “Part A”), with publication dates between 1978 and 1985. Each part contained a ser
21、ies of “sections”, each designated by the respective part letter and by a two-digit serial number (e.g., “Section A02”). These sections are being republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric designations. A complete list of these parts is
22、given in ISO 105-A01. EN ISO 105-C12:2006iv Introduction The test method in this part of ISO 105 is intended to reflect the effect of comprehensive laundering during industrial laundry procedures, as distinct from the domestic washing test methods as given in ISO 105-C05, ISO 105-C06 and ISO 105-C08
23、. Four test conditions are described, one at (92 2)C intended for the evaluation of workwear and three, as given below, at (75 2) C, for the evaluation of bed and table linen and corporate wear: without the addition of peroxy bleach compounds; with the addition of hydrogen peroxide (for the bleachin
24、g of white work with coloured trimmings); with the addition of sodium perborate tetrahydrate and tetra-acetylethylene diamine (TAED) (for the bleaching of white work with coloured trimmings). NOTE The addition of TAED/perborate is a conveniently stable way of producing peracetic acid in situ. This m
25、ethod of test does not reflect the effect of optical brightening agents. This method and the single cycle test methods described in ISO 105-C06 and ISO 105-C08 may not reproduce the effect of coloured fabrics treated with certain dye fixing agents and finishes after multiple (5 to 10) industrial was
26、hes. EN ISO 105-C12:20061Textiles Tests for colour fastness Part C12: Colour fastness to industrial laundering 1 Scope This part of ISO 105 specifies methods for determining the resistance of the colour of textiles of all kinds exposed to all forms of industrial laundering procedures. One cycle appr
27、oximates to the colour loss and cross staining resulting from chemical and/or mechanical action achieved after multiple (5 to 10) industrial launderings. 2 Normative references The following referenced documents are indispensable for the application of this document.

32、and dried. Specimens are laundered under appropriate conditions of temperature, alkalinity, bleaching and mechanical action such that the result is obtained in a conveniently short time. The mechanical action is accomplished by the use of an appropriate number of steel balls. The change in colour of
33、 the specimens and the staining of the adjacent fabrics are assessed using the grey scale. EN ISO 105-C12:20062 4 Reagents NOTE All chemicals should be of at least general purpose laboratory grade. 4.1 Detergent, as specified in Annex A. 4.2 Solution, containing 0,2 g/l of glacial acetic acid, if re
34、quired for souring treatment. 4.3 Hydrogen peroxide solution, 30 %. 4.4 Sodium hydroxide (NaOH) pellets. 4.5 Tetra-acetylethylenediamine (TAED). 4.6 Sodium perborate tetrahydrate. 4.7 Distilled water, grade 3 water (see 8.2 of ISO 105-A01:1994) 5 Apparatus 5.1 Suitable mechanical device, consisting
35、of a water bath containing a rotatable shaft which supports, radially, stainless steel containers (75 5) mm diameter (125 10) mm high of capacity (550 50) ml, the bottom of the containers being (45 10) mm from the centre of the shaft. The shaft/container assembly is rotated at a frequency of (40 2)
36、min1. The temperature of the water bath is thermostatically controlled to maintain the test solution at the prescribed temperature ( 2)C. NOTE Other mechanical devices may be used for this test, provided that the results are identical with those obtained by the apparatus described. 5.2 Mechanical st

38、nt fabrics, one cotton and one polyester, in accordance with ISO 105-F02 and ISO 105-F04 or as otherwise specified between interested parties. 5.4.3 If required, a non-dyeable fabric (e.g. polypropylene) (e.g. to mechanically stabilize a knitwear specimen). 5.5 Grey scale, for assessing change in co
39、lour in accordance with ISO 105-A02, or instrumentally ISO 105-A05, and for assessing staining in accordance with ISO 105-A03, or instrumentally ISO 105-A04. 5.6 Flat-iron, of mass not exceeding 2,5 kg ( 100 g) and capable of giving the temperature indicated in 7.2.5, if a pressing treatment is requ

EN ISO 105-C12:200636 Test specimens 6.1 Fabric specimen Cut two fabric test specimens each 80 mm 160 mm, one specimen in the warp direction and one specimen in the weft direction. In the case o
41、f knitwear prepare two specimens. Weigh the two specimens to two decimal places (grams). Fold each specimen across the narrow dimension in the centre of the specimen with fabric face on the outside (see Figure 1). Using dimensionally stable thread, sew along the two sides to form a bag. Place 25 sta
42、inless steel balls inside each bag and seal by sewing. 6.2 Adjacent fabrics Either: a) cut a sample of multifibre TV adjacent fabric (5.4.1) and weigh to two decimal places (grams); or b) cut a sample 100 mm 80 mm, of the two single-fibre adjacent fabrics (5.4.2) and weigh to two decimal places (gra
43、ms). NOTE The two-fabric test specimen and adjacent staining fabrics are not sewn to each other. This allows fabric abrasion to occur.
