1 Scope
This part of ISO 105 specifies a method for determining the resistance of the colour of textiles of all
kinds and in all forms to the action of human perspiration.

3 Principle
Specimens of the textile in contact with adjacent fabrics are treated in two different solutions containing
histidine, drained and placed between two plates under a specified pressure in a test device. The
specimens and the adjacent fabrics are dried separately. The change in colour of each specimen and the
staining of the adjacent fabrics are assessed by comparison with the grey scales or instrumentally.
4 Apparatus and materials
4.1 Test devices, each consisting of a frame of stainless steel into which a weight-piece of mass
approximately 5 kg and base 60 mm × 115 mm is closely fitted, so that a pressure of (12,5 ± 0,9) kPa can
be applied on test specimens measuring (40 ± 2) mm × (100 ± 2) mm, placed between glass or acrylicresin
plates measuring approximately 60 mm × 115 mm × 1,5 mm. The test device shall be constructed so
that, if the weight-piece is removed during the test, the pressure remains unchanged.
If the dimensions of the composite specimen differ from the size of (40 ± 2) mm × (100 ± 2) mm, the
weight-piece used shall be such that a nominal pressure of (12,5 ± 0,9) kPa is applied to the specimen.
Other devices may be used provided that equivalent results are obtained.
4.2 Oven, maintained at (37 ± 2) °C.
4.3 Alkaline solution, freshly prepared, using grade 3 water complying with ISO 3696, containing, per
litre:
— 0,5 g of l-histidine monohydrochloride monohydrate (C6H9O2N3·HCl·H2O);
— 5 g of sodium chloride (NaCl);
and either
— 5 g of disodium hydrogen orthophosphate dodecahydrate (Na2HPO4·12H2O)
or
— 2,5 g of disodium hydrogen orthophosphate dihydrate (Na2HPO4·2H2O).
The solution is brought to pH 8 (±0,2) with 0,1 mol/l sodium hydroxide solution.
4.4 Acid solution, freshly prepared, using grade 3 water complying with ISO 3696, containing, per litre:
— 0,5 g of l-histidine monohydrochloride monohydrate (C6H9O2N3·HCl·H2O);
— 5 g of sodium chloride (NaCl);
— 2,2 g of sodium dihydrogen orthophosphate dihydrate (NaH2PO4·2H2O).
The solution is brought to pH 5,5 (±0,2) with 0,1 mol/l sodium hydroxide solution.
4.5 Adjacent fabrics (see ISO 105-A01).
Either:
4.5.1 A multifibre adjacent fabric complying with ISO 105-F10.
or:
4.5.2 Two single-fibre adjacent fabrics, complying with the relevant document selected from
ISO 105-F01 to F06.
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, the second piece being made of the fibre indicated in Table 1 or, in
the case of blends, of the kind of fibre that is second in order of predominance, or as otherwise specified.
