6.4 Appearance quality requirements

6.4.1 Classification of appearance defects

If a single product does not meet the technical requirements specified in this Document, it constitutes a defect.

According to the degree of non-compliance of the product with the requirements of this Document and the degree of impact on the product's wearing performance and appearance, defects are divided into three categories:

a) Severe defects Defects that seriously reduce the product's wearing performance and seriously affect the product's appearance are called severe defects.

b) Serious defects Defects that do not seriously reduce the product's wearing performance and do not seriously affect the product's appearance, but are more seriously inconsistent with the provisions of the standard, are called severe defects.

c) Minor defects Defects that do not meet the provisions of the standard but have a minor impact on the product's wearing performance and appearance are called minor defects.

The detergent is "standard detergent 3" and the drying program is A-hanging drying. The arithmetic mean of the three specimens is used as the test result. If there are shrinkage and elongation test results at the same time, the arithmetic mean of the two shrinkage (or elongation) specimens is used as the test result. The final result is rounded off according to GB/T 8170 to one digit after the decimal point.

8.2 Appearance quality

The appearance quality grade of finished products is determined based on the existence and severity of defects. The single product in the sampling sample is graded according to the number of defects and their severity; and the batch product grade is divided according to the number of single products in the sampling sample.

Single (sample)

Superior products: the number of severe defects is equal to 0; the number of serious defects is equal to 0; and the number of minor defects is less than or equal to 4;

First-class products: the number of severe defects is equal to 0; the number of serious defects is equal to 0; the number of minor defects is less than or equal to 7. Or the number of severe defects is equal to 0; the number of serious defects is equal to 1; and the number of minor defects is less than or equal to 3;

Qualified products: the number of severe defects is equal to 0; the number of serious defects is equal to 0; the number of minor defects is less than or equal to 8. Or the number of severe defects is equal to 0; the number of serious defects is equal to 1; and the number of minor defects is less than or equal to 6.

Batch (sample)

Superior product batch: the number of superior products in the appearance sample is greater than or equal to 90%; and the number of first-class products and qualified products is less than or equal to 10% (excluding unqualified products).

First-class product batch: the number of products above first-class products in the appearance sample is greater than or equal to 90%; and the number of qualified products is less than or equal to 10% (excluding unqualified products).

Qualified product batch: the number of products above qualified products in the appearance sample is greater than or equal to 90%; and the number of unqualified products is less than or equal to 10% (excluding unqualified products with severe defects).

8.3 Comprehensive judgment

If the judgments in 8.1 and 8.2 are both qualified, then the batch of products is qualified.
