Foreword

This Document was drafted as per the rules specified in GB/T 1.1-2020 Directives for

Standardization – Part 1: Rules for the Structure and Drafting of Standardizing Documents.

This Document replaced GB/T 29865-2013 Textiles - Tests for Color Fastness - Color Fastness

to Rubbing - Small Areas. Compared with GB/T 29865-2013, the major technical changes are

as follows besides the structural adjustments and editorial modifications:

--- Change the requirements for rubbing cloth; and replace GB/T 7568.2 with GB/T 33729

(see 5.2 of this Edition; 4.2 of the 2013 Edition);

--- Change the "NOTE" in 5.3 to a clause (see 5.3 of this Edition; 4.3 of the 2013 Edition);

--- Add the content related to "balance" (see 5.5 of this Edition);

--- Add a clause on "reagents"; add a reference to GB/T 6682; and supplement the

requirements for test water (see Clause 6 of this Edition);

--- Add the description "Under negotiation between the relevant parties, it is also possible

to adjust the humidity under the optional standard atmosphere specified in GB/T 6529,

which shall be stated in the test report. The specimen and rubbing cloth are placed on a

sieve or a perforated rack for humidity-adjusting. For example, fabrics such as cotton or

wool may require a longer humidity-adjusting time." (see 7.3 of this Edition; 5.3 of the

2013 Edition);

--- Change the requirements for humidity-adjusting before rating (see 8.2 of this Edition;

10 of this Edition; Clause 10 of the 2013 Edition).

This Document modified and adopted ISO 105-X16:2016 Textiles – Tests for Color Fastness –

Part X16: Color Fastness to Rubbing – Small Areas. Compared with ISO 105-X16:2016, this

Document made the following structural adjustment:

--- Add "Terms and Definitions" (see Clause 3 of this Document);

--- Add "Reagents" (see Clause 6 of this Document);

--- Merge the contents of 6.4 in ISO 105-X16:2016 into 6.3 (see 8.3 of this Document; 6.3

and 6.4 of ISO 105-X16:2016).

Textiles – Tests for Color Fastness – Color Fastness to

Rubbing – Smal Areas

1 Scope

This Document describes the test method for the color fastness to rubbing of textiles, where the

test area is smaller than the test area specified in GB/T 3920.

This Document includes two tests, one using a dry rubbing cloth and the other using a wet

rubbing cloth.

For the purposes of this Document, there are no terms and definitions apply.

1) ISO 105-A03:1993 has been replaced by ISO 105-A03:2019.

7 Specimens

7.1 If the textile to be tested is a fabric, prepare a specimen with a size of no less than 25 mm×25

mm. If the test accuracy is higher, the number of specimens can be increased.

7.2 If the textile to be tested is yarn, it shall be woven into a fabric with a specimen size of no

less than 25 mm × 25 mm; or the yarn shall be wound parallel to the length direction of a

rectangular cardboard so that the yarn is evenly spread into one layer on a cardboard of suitable

size.
