Item Limit value
Free formaldehyde, ≤ 75
Decomposable harmful aromatic amine dye, ≤ 30
Note. The name of the forbidden aromatic amine is as shown in Appendix A in GB 20400. If the content
of the 4-aminobiphenyl and 2-aniline exceeds 30 mg/kg, and there is no other evidence, it cannot judge
whether the forbidden azo dye is used based on the currently available knowledge.
one test, totally 200 tests are performed, respectively.
6.5 Zipper durability
Select 20 cm length zipper to perform test at the frequency of (20 ± 1) time/min,
one opening plus one closing form one test, totally 200 tests are made. If the
zipper length is less than 20 cm, perform test within the maximum length range
of the zipper.
6.6 Hardware fitting corrosion resistance
It is tested in accordance with QB/T 3826 (excluding riveted piece, metal chain
tooth), the test time is 16 h. Only the zipper pull of the zipper head is evaluated.
7 Inspection rules
7.1 Batching
The products of the same type and same specification which are produced by
the same type of raw materials in accordance with the same production process
form one inspection batch.
7.2 Exit-factory inspection
Each batch of products shall be subject to appearance inspection one by one,
which can only be exit-factory after being inspected and qualified.
7.3 Conventional type inspection
Under one of the following cases, it shall randomly take 3 products from those
which passes exit-factory inspection for conventional type inspection.
a) In case of major change of product structure, process, and material;
b) In case of production restoration after 6-month suspension;
c) In case of national quality technical supervision institute proposes type
inspection;
d) In case of normal production, at least 1 type inspection is made every 6
months.
7.4 Special type inspection
It is performed in accordance with the provisions of Appendix C.
7.5 Decision rules
Appendix B
(Normative)
Test methods for color fastness to rotatory rubbing
B.1 Test environment
The specimen shall be placed in a standard environment of temperature (20 ±
2) °C and relative humidity (65 ± 4)% for conditioning for at least 24 h, the test
shall also be performed at this temperature and humidity conditions.
B.2 Test instrument and material
B.2.1 Rotatory rubbing testing machine
It shall contain the following parts.
- Test bench (preferably metal), which can fix the specimen;
- Vertical rotatory shaft, which is used to fix the circular felt, the rotation speed
is (150 ± 5) r/min;
- Apply the (24.5 ± 0.5) N or (7.1 ± 0.2) N to the rotating circular felt;
- Counter.
B.2.2 Test material
Circular combed felt, with holes at middle part, which shall comply with the
following requirements.
- Outer diameter (25 ± 1) mm, inner diameter (3.0 ± 0.5) mm;
- Thickness, which is measured in accordance with the provisions of Table
B.1;
- Density (190 ± 20) kg/m3.
Table B.1 -- Felt thickness test method
Thickness/mm Downward pressure/pressure foot size Sample
6.5 ± 0.5 (49 ± 5) kPa/(10 ± 1) mm Cut felt or sheet material not cut
5.0 ± 0.5 (2.0 ± 0.2) kPa/(19 ± 10) mm Cut felt
B.3 Specimen preparation
The requirements are as follows.
- When the sample can be flatly fixed onto the test bench, it may directly use
the sample to perform test;
- When the sample cannot be flatly fixed onto the test bench, cut a strip
specimen of 30 mm x 90 mm from the sample surface layer material to
perform test.
Test shall be performed on parts free from stitching lines or holes.
B.4 Test
B.4.1 Dry rubbing test
B.4.1.1 Fix the specimen onto the test bench, apply the load, to make the test
head pressure reach to (24.5 ± 0.5) N.
B.4.1.2 Fix the felt onto the test machine shaft.
B.4.1.3 Lower down the rotating shaft, to make the felt contact to the specimen,
select the number of rotations in accordance with Table B.2, start the instrument.
B.4.1.4 After the test, rise the rotating shaft, take off the specimen and felt, use
the grey scale as specified in GB/T 251 to assess the staining grade of the felt.
B.4.2 Wet rubbing test
B.4.2.1 Weight the mass of dry felt, place the dry felt into the grade III water or
deionized water, slowly heat it to boiling, keep boiling for 60 s, pour off hot water,
replace fresh water, to make the circular felt cool to room temperature, take the
felt off water, place it in between 4 water absorbent papers (2 above and 2
below, with the test surface in contact with the filter paper horizontally), place a
(900 ± 10) g load onto the filter paper, keep it for about 1 min, gently extrude
the circular felt to adjust its moisture, weigh it to make the wet felt mass reach
to (3.0 ± 0.3) g, the immersion time of the circular felt in water shall not exceed
24 h.
B.4.2.2 Fix the specimen onto the test bench, make the test head pressure be
(7.1 ± 0.2) N.
B.4.2.3 Fix the wet felt onto the test machine shaft.
B.4.2.4 Lower down the rotating shaft, to let the felt contact the specimen, select
the number of rotations in accordance with Table B.2, start the instrument.
B.4.2.5 After the test, rise the rotating shaft, take off the specimen and felt,
naturally dry the felt at room temperature, use the grey scale as specified in
GB/T 251 to assess the staining grade of the felt.
