ISO 105-C12:2004(E)
Foreword
ISO (the 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 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 electrotechnical 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 bodies 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 any 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 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 complete list of these parts is given in ISO 105-A01.
ISO 105-C12:2004(E)
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. 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 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 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 fixing agents and finishes after multiple
(5 to 10) industrial washes.

Textiles — 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 approximates to the colour loss and cross staining resulting from chemical and/or mechanical
action achieved after multiple (5 to 10) industrial launderings.

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 conveniently 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.

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 required 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 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
−1
rotated at a frequency of (40 ± 2) min . 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.
−1
5.2 Mechanical stirrer, minimum (1 100 ± 100) min or equivalent, to ensure dispersion and prevent
settling.
5.3 Steel balls, non-corrodible (stainless), approximately 6,0 mm in diameter.
5.4 Adjacent fabrics.
5.4.1 A multifibre adjacent fabric complying to type (TV) of ISO 105-F10:1989
or
5.4.2 Two single-fibre adjacent 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 colour 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 required. Condition the sample for 24 h before assessing to allow for
temporary colour change caused by heat.

6 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 of 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 stainless 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 (grams).
NOTE The two-fabric test specimen
