4.1.4 1/12 Color cards of standard depths for dyeing with dyestuffs (GB/T 4841.3).

4.2 Finished-product specification determination

4.2.1 The specification of the main parts of finished-product is according to 3.2

regulations.

4.2.2 The measurement of the main parts of finished-product is according to GB/T

31907; allowed specification deviation is according to 3.8 regulations.

4.3 Appearance determination

4.3.1 The appearance determination of finished-product generally uses lighting; the

illumination is no less than 600 lx. If possible, use north-sky-light illumination too.

4.3.2 When assessing the degree of finished-product's color difference, incident light

is about 45° to the surface of fabric. The observation direction shall be perpendicular

to the surface, and the distance shall be 60cm from visual inspection, compared with

GB/T 250 sample card.

4.3.3 The appearance quality of finished-product is according to 3.6 regulations.

4.3.4 The sewing quality of finished-product is according to 3.7 regulations.

4.3.5 Ironing of finished-product is according to 3.9 regulations.

4.4 Determination of physical-chemical properties

4.4.1 Limit for hazardous substances of PVC artificial leather of finished-product is

tested according to the provisions of GB 21550.

4.4.2 Tensile strength, peeling strength, tearing strength and anti-yellowing of

finished-product are tested according to the provisions of GB/T 8949.

4.4.3 Flexing endurance of finished-product is tested according to the provisions of

QB/T 2714, and use dry samples.

4.4.4 Anti-blocking of finished-product is tested according to the provisions of

Appendix A.

4.4.5 Alkali solution hydrolysis fastness of finished-product. prepare 3 samples of size

4cmX6cm. Place the test sample and a certain amount of sodium hydroxide solution --

temperature (23 ± 2) °C, concentration of 5% -- together into a flat-bottom glass

container; immerse it for 24h at room temperature. If necessary, add additional mass

to the test sample in order to immerse the test sample in the solution completely. Take

out the sample from the solution. Rinse it thoroughly with deionized water. Observe

the erosion cracking of the surface and the separation of outside-inside layers after

drying at room temperature.

4.4.6 Other physical-chemical properties are tested according to the provisions of

GB/T 21294, in which the main types of artificial leather coatings shall be tested in

accordance with the provisions of GB/T 6040.

4.4.7 The test items which do not mention the sampling location are according to the

needs to select the sample from the finished-product.

5.1 Inspection classification

5.1.1 Finished-product inspection is divided into factory inspection and type

inspection.

5.1.2 Factory inspection is according to the provisions of Chapter 3 (except 3.10).

Factory inspection rules of finished-product are according to the provisions of FZ/T

80004.

Sample 20 pieces for 500 to 1000 pieces (including 1000 pieces).

Sample 30 pieces for more than 1000 pieces.

Sampling for physical-chemical properties will sample at least 4 pieces according

to the items.

5.4 Decision rules

5.4.1 Appearance determination for single piece (sample)

Top-grade product. Serious defects = 0 Heavy defects = 0 Light defects <= 4

First-grade product. Serious defects = 0 Heavy defects = 0 Light defects <= 7 or

Serious defects = 0 Heavy defects <= 1 Light defects <= 3

Qualified product. Serious defects = 0 Heavy defects = 0 Light defects <= 8 or

Serious defects = 0 Heavy defects <= 1 Light defects <= 6

5.4.2 Batch determination

If one item or above is not qualified according to physical-chemical properties, the

sampled batch is not qualified.

Top-grade product batch. in sample appearance, the number of top-grade product is

more than 90%, the number of first-grade and qualified products is less than 10%.

Physical-chemical properties test can achieve the index requirements of top-grade

product.

First-grade product batch. in sample appearance, the number of first-grade product or

above is more than 90%, the number of qualified product is less than 10% (excluding

non-qualified product). Physical-chemical properties test can achieve the index

requirements of first-grade product.

Qualified product batch. in sample appearance, the number of qualified products...
