3 Product sizing
The sizing of knitted shirt products shall be in accordance with the requirements of GB/T 1335 (all parts) or GB/T 6411. The sizing beyond the standard range may be increased or decreased in sequence according to the grading values and principles specified in the standard.
4 Requirements
4.1 Grading requirements
4.1.1 The products are classified into superior products, first-grade products and acceptable products in terms of the quality grade.
4.1.2 Grading of quality: The products are graded by batches (delivery batch) in terms of inherent quality and by pieces in terms of appearance quality, and the lower grade shall prevail in case of a combination of both.
4.1.3 For all inherent quality indexes, the lowest grade of the test result is regarded as the grading basis for this batch of products.
4.1.4 Where appearance defects with different product grades exist on the same product, the product shall be graded according to the lowest quality grade. For one product, only two limit surface defects of the same grade are allowed; otherwise, it shall be degraded by one grade.
