6.1.6 Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)

According to GB/T 31126.

6.1.7 Dimensional change after washing

Take 3 specimens from the sample. Test according to GB/T 8630. Wash according to the 4N program of A-type washing machine in GB/T 8629-2017. Select "Standard Detergent 3" as the detergent. Select A-hanging and drying as the drying program. Wash once. Take the arithmetic mean of the 3 specimens as the test result. If there are shrinkage and elongation test results at the same time, take the arithmetic mean of the 2 specimens with the same shrinkage (or elongation) as the test result. The final result is rounded according to GB/T 8170, retaining one decimal place.

6.1.8 Pilling

It shall be implemented in accordance with Parameter D in GB/T 4802.1-2008.

6.1.9 Wear resistance

According to GB/T 21196.2, wool abrasive is used. The total effective mass of friction load is (595 ± 7) g (nominal pressure is 9 kPa).

6.1.10 Tearing strength

According to GB/T 3917.2.

6.1.11 Seam strength of back crotch seam

6.1.18 Surface moisture resistance

Follow the provisions of GB/T 4745. Washing method follows the provisions of 4N program of A-type washing machine in GB/T 8629-2017. Use "Standard Detergent 3" as detergent. Use A-hang to dry as drying program. Wash 3 times. Hang to dry after each wash.

6.1.19 Hydrostatic pressure

Fabrics with elastic elongation >=10% in either warp (vertical) or weft (horizontal) direction are tested according to the method for determining the final hydrostatic pressure value in FZ/T 01004-2008. The water pressure rise rate is (6.0±0.3) kPa/min.

The test end point is in accordance with GB/T 4744. Other fabrics are in accordance with GB/T 4744. The hydrostatic pressure sampling location at the seam is the flat seam tape (except the cross section). The lowest hydrostatic pressure value of the fabric and the fabric seam is used as the hydrostatic pressure value of the sample for determination.

The washing method shall be in accordance with the washing method for surface moisture resistance in 6.1.18.

The tensile elastic elongation is tested according to FZ/T 01034. The fixed force value is 25 N.

6.1.20 Moisture permeability

The test conditions a) and method B (inverted cup method) in GB/T 12704.2-2009 shall be followed. The washing method shall be followed as specified in 6.1.18 on the washing method for surface moisture resistance.

6.1.21 Buttons, decorations, zippers and other accessories

The accessible sharp edges and sharp points shall comply with the provisions of GB/T 31702. Other tests shall refer to 6.2.1 and 6.2.2 of the appearance quality inspection method.

6.1.22 Residual metal needle inspection

It is implemented in accordance with GB/T 24121. The detection sensitivity (standard iron ball test card) is 1.0 mm.

6.1.23 Appearance after washing

After washing and drying according to the water washing size change test method specified in 6.1.7, evaluate in combination with Table 1.

8.1.2 Single piece determination

If the number of product inspection pieces is lower than the number of sampling pieces for batch determination, only the inspected samples shall be determined in accordance with 7.1.1 and this shall be noted in the inspection report.

8.2 Appearance quality

The appearance quality grade of finished products is determined by the presence and severity of defects. The individual products in the sample are graded by the number of defects and their severity. The batch grade is divided by the quality ratio of the individual products in the sample.

Superior products. Serious defects = 0 Major defects = 0 Minor defects <= 4

First-class products. Serious defects = 0 Major defects = 0 Minor defects <= 7 or Serious defects = 0 Major defects = 1 Minor defects <= 3

Qualified products. Serious defects = 0 Major defects = 0 Minor defects <= 8 or Serious defects = 0 Major defects = 1 Minor defects <= 6

Superior batch. the number of superior products in the appearance sample is >=90%, and the number of first-class products and qualified products is < 10% (excluding unqualified products).

First-class batch. the number of first-class and above products in the appearance sample is >=90%, and the number of qualified products is < 10% (excluding unqualified products).

Qualified batch. The number of qualified products in the appearance sample is >=90%, and the number of unqualified products is < 10% (excluding unqualified products with […]
