7、International Organization for 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
8、 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnic
9、al standardization. International 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 bo
10、dies for voting. Publication as 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 an
11、y or all such patent rights. ISO 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
12、1985. Each part contained a series 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 c
13、omplete list of these parts is given in ISO 105-A01. -,-,- ISO 105-C12:2004(E) iv ISO 2004 All rights reserved 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 washin
14、g test methods as given in ISO 105-C05, ISO 105-C06 and ISO 105-C08. 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
15、compounds; with the addition of hydrogen peroxide (for the bleaching 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
16、conveniently stable way of producing peracetic acid in situ. This method 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

18、 the resistance of the colour of textiles of all kinds exposed to all forms of industrial laundering procedures. One cycle approximates to the colour loss and cross staining resulting from chemical and/or mechanical action achieved after multiple (5 to 10) industrial launderings. 2 Normative referen

23、conditioning and testing 3 Principle A specimen of the textile in contact with specified adjacent fabrics is laundered, rinsed and dried. Specimens are laundered under appropriate conditions of temperature, alkalinity, bleaching and mechanical action such that the result is obtained in a convenientl
24、y short time. The mechanical action is accomplished by the use of an appropriate number of steel balls. The change in colour of the specimens and the staining of the adjacent fabrics are assessed using the grey scale. ISO 105-C12:2004(E) 2 ISO 2004 All rights reserved 4 Reagents NOTE All chemicals s
