1 Scope
This document describes three methods for evaluating the surface color migration of
materials in dry and wet rubbing (methods A, B, C), as well as a method for determining
the possibility of color bleeding (method D).
This document is applicable to the determination of color fastness to rubbing and

is also applicable to the determination of color fastness of color bleeding of stitches and
shoelaces.
The methods are as follows:
- Method A: Square head reciprocating rubbing color fastness;
- Method B: Rotating rubbing color fastness;
- Method C: Round head reciprocating rubbing color fastness;
- Method D: Bleeding color fastness.

the pH before use and adjust it as needed. If solid precipitate appears, discard the
solution.
5 Sampling and environmental conditioning
5.1 Method A
5.1.1 The rectangular specimen is required to be large enough to be firmly clamped on
the test platform (4.1.1.1). The specimen can be taken in any direction of the material.
In general, the minimum size of the specimen shall be 100 mm × 25 mm. If it is a tensile
material, it should take sample from the direction with less elasticity.
When using a test machine with a test platform width of 25 mm, the specimens are
grouped according to the number of rubbings or test conditions.
For test machines with a wider test platform, the rubbing head (4.1.1.5) can be adjusted
and installed at different positions of the platform width; wider specimens can be used
so that separate rubbing tracks can be used side by side.
5.1.2 Before the test, place the specimen in the standard environment specified in GB/T
22049 for at least 24 hours.
Note: Samples can be taken from shoe materials, molded uppers or finished shoes.
5.2 Method B
5.2.1 The specimen size shall be large enough to be firmly fixed on the test platform
(4.2.1.1). In general, the specimen shall be a 60 mm × 60 mm square, or a 60 mm
diameter circle; or a 60 mm wide strip specimen can be used for multiple tests.
For raw materials, samples are taken from a series of positions throughout the available
width and length of the sheet. For materials with a woven structure, either of these two
specimens should not have the same warp or weft.
For the upper surface, avoid sampling at seams, perforations, and other locations where
flat specimens cannot be taken.
5.2.2 Before the test, place the specimen in the standard environment specified in GB/T
22049 for at least 24 hours.
5.3 Method C
5.3.1 Two representative specimens, each with a size of not less than 140 mm × 50 mm.
One for dry rubbing and the other for wet rubbing. For tensile materials, the specimen
should be taken from the direction with less elasticity.
5.3.2 Before the test, place the specimen in the standard environment specified in GB/T

Foreword
This Standard equivalently adopted the international standard ISO 17700:2004
Footwear – Test Methods for Uppers, Linings and Insocks – Colour Fastness to
Rubbing (English Version).
The major differences between this Standard and ISO 17700:2004 are as follows:
In this standard, based on the geographical location of China, the original text "test in
the northern hemisphere, use daylight from the north. If test in the southern
hemisphere, use daylight from the south." is changed into "if daylight source is used,
use daylight from the north".
Convert the "rad/s" unit in the international standard to "r/min", which is a common
speed unit in China.
For ease of use, this Standard has also made the following editorial modifications:
a) Change the term "this European Standard" into "this Standard";
b) Use a decimal point "." to replace the comma "," that are used as the decimal
point;
c) Delete the Foreword of the international standard;
d) Delete the Contents of the international standard.
Annex A of this Standard is an informative.
This Standard was proposed by China National Light Industry Council.
This Standard shall be under the jurisdiction of National Footwear Standardization
Centre.
Drafting organization of this Standard: China Leather and Footwear Industry Research
Institute.
Chief drafting staffs of this Standard: Yan Huaidao, Qi Xiaoxia, Zhang Weijuan, and
Yan Hongwei.
This Standard was first-time published.
Footwear – Test Methods for Uppers, Linings and
Insocks – Colour Fastness to Rubbing
1 Scope
1.1 This Standard specifies two test methods (method A and method B) for assessing
the degree of damage (marring) and transfer of a material’s surface colour during the
dry or wet abrasion. The methods are applicable to all footwear uppers, linings and
insocks irrespective of the material, in order to assess suitability for end use.
1.2 This Standard also specifies a method (method C) for determining the likelihood of
colour bleeding from materials and components such as sewing threads and shoe
laces due to the action of water and artificial perspiration solutions, in order to assess
suitability for end use.
