3 Product Sizing Systems
The sizing systems of knitted T-shirts shall be in accordance with the requirements of FZ/T 70014 or GB/T 1335.
4 Requirements
4.1 Requirement contents
The requirements include inherent quality and appearance quality, in which the inherent quality includes such indicators as fiber content, formaldehyde content, pH value, odor, decomposable carcinogenic aromatic amine dyes, dimensional stability to washing, distortion rate after washing, bursting strength, pilling, color fastness to light-perspiration/light/washing with soap/water/perspiration/rubbing, colour fastness of printing (pyrography) to washing with soap/rubbing, splicing and cross dyeing degree, and appearance quality after washing. While the appearance quality includes such indicators as surface defect, specification and size deviation, size difference in symmetrical positions and sewing requirements.
4.2 Grading requirements
4.2.1 Knitted T-shirts are classified into high-grade products, first-grade products and qualified products.
4.2.2 As for the quality grading of knitted T-shirts, the inherent quality is graded by batch, while the appearance quality is graded by piece, and the knitted T-shirts shall be graded as the lowest grade between them.
4.2.3 For all of the inherent quality indicators, the lowest test result shall be the quality criterion for this batch of products.
4.2.4 Where appearance quality problems of different grades are found on the same product, the product shall be graded as the lowest quality grade. For one product, only two limit surface defects of the same grade are allowed; otherwise, it shall be reduced by one grade.
4.3 Inherent quality requirements
4.3.1 See Table 1 for the inherent quality requirements.
