Note 2: colour classification shall be in accordance with GSB-2159, the colour greater than 1/12 standard depth as the dark one and the colour less than or equal to 1/12 standard depth as the light one. 4.3.1 The inherent quality of this batch of products shall be graded based on the lowest inspection result of each index. 4.3.2 As for pilling, only the front is assessed. Pilling is not assessed for sanding products, and gigging products, etc. 4.3.3 Marble bursting strength is not assessed for stretch fabrics, hollowed-out products and burnt-out products. 4.3.4 Transverse washing dimensional change ratio is not assessed for elastic fiber fabrics and that along the wrinkle direction is not assessed for wrinkled products. 4.3.5 Abbuting and cross dyeing degree is only assessed for the products abbuted with dark ones and light ones. 4.3.6 Colour fastness to light of textiles wetted with artificial perspiration is not assessed for the products not directly exposed to the skin. 4.3.7 Distortion ratio after washing is not assessed for the products with bishop sleeves or the coats and skirts with non-straight hems. 4.3.8 Colour fastness to dry cleaning is only assessed for the dry-cleanable products indicated in the instructions for use; colour fastness to washing with soap or soap and soda and colour fastness of printing (pressing) to washing with soap or soap and soda are only assessed for the washable products indicated. 4.3.9 Drycleaning dimensional change ratio is only assessed for the dry-cleanable products indicated in the instructions for use; washing dimensional change ratio is only assessed for the washable products indicated in the instructions for use.
