BRIEF HISTORY
The IS0 Recommendation R 105/111, Tests for Colour Fastness of Textiles-Third
Series, was drawn up by Technical Committee ISO/TC 38, Textiles, the Secretariat of which
is held by the British Standards Institution (B.S.I.).
Work on this question by the Technical Committee began in 1954 and led, in 1958,
to the adoption of a Draft IS0 Recommendation.
In October 1960, this Draft IS0 Recommendation (No. 405) was circulated to all the
IS0 Member Bodies for enquiry. It was approved, subject to a few modifications of an
editorial nature, by the following Member Bodies :
Australia Greece Poland
Austria Hungary Republic of South Africa
India
Belgium Romania
Canada Iran Spain
Chile Israel Sweden
Czechoslovakia Japan Turkey
Denmark Netherlands United Kingdom
France New Zealand U.S.S.R.
Germany Norway
Three Member Bodies opposed the approval of the Draft:
Italy, Switzerland, U.S.A.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in March 1963, to accept it as an IS0 RECOMMENDATION.

TESTS FOR
COLOUR FASTNESS OF TEXTILES
THIRD SERIES
Part 1
COLOUR FASTNESS TO STEAMING UNDER ATMOSPHERIC PRESSURE
1. PURPOSE AND SCOPE
1.1 This method is intended for assessing the resistance of the colour of textiles of all kinds
and in all forms to the action of steaming under atmospheric pressure.
2. PRINCIPLE
2.1 A specimen of the textile in contact with specified undyed, cloths is rolled into a cylinder
and placed in the neck of a flask containing boiling water. The staining of the undyed
cloths is assessed with grey scales.
3. APPARATUS AND REAGENTS
3.1 An Erlenmeyer flask with a glass tube open at both ends inserted in the neck (see clause 7.1
and figure, page 6).
3.2 Undyed, scoured cloth, 10 cm x 4 cm, of the same fibre as the specimen.*
3.3 Undyed bleached cotton cloths, each 10 cm x 4 cm.
3.4 Undyed scoured wool felt.
3.5 Standard grey scale for assessing staining.*
4. SPECIMEN
4.1 If the textile to be tested is fabric, prepare a composite specimen measuring 10 cmx4 cm**
by placing successively on a piece of cotton cloth as in clause 3.3 the textile to be tested,
a piece of cloth as in clause 3.2 and a further piece of cotton cloth as in clause 3.3. Roll
this composite specimen into a cylinder, with the cloth being tested as near as possible to
the middle.
4.2 If the textile to be tested is yarn, knit it into cloth and use a piece 10 cmx4 cm and treat
as in clause 4.1.
* See ISO,GRecommendation R 105/I, Tests for Colour Fastness of Textiles (First Series) :
Part 1 : General principles of testing”,
Part 3 : “ Grey scale for assessing staining ”.
** The length of 10 cm may be reduced if the cloth to be tested is too thick for the cylinder to be inserted into the tube.
To facilitate rolling, stitch at one end the cloth (knitted yarn or fibre) forming the composite specimen.

4.3 If the textile to be tested is loose fibre, comb and compress enough of it to form a sheet
10 cm x 4 cm, place it on a piece of undyed cotton cloth as in clause 3.3; place successively
on this a piece of undyed cloth as in clause 3.2 and a further piece of cotton cloth as in
clause 3.3. Roll the composite specimen into a cylinder, with the fibre to be tested as near
the middle as possible.
5. PROCEDURE
5.1 Bring the water in the conical flask to the boil. Wrap the cylindrical composite specimen
in felt as in clause 3.4 so that the whole fits easily in the glass tube in the neck of the flask
and can be retained by the indentations in the lower part of the tube, and boil for 30 minutes.
5.2 Remove the composite specimen from the
