The inherent quality includes indexes for fiber content, formaldehyde content, pH value, peculiar smell, decomposable carcinogenic aromatic amine dyes, heavy metal, phthalic acid esters, combustion performance, filler, accessories, extractable heavy metal content, dimensional change rate in water washing, pilling, tensile strength of the garment belt, colour fastness to saliva, colour fastness to water, colour fastness to perspiration, colour fastness to soaping, colour fastness to rubbing, colour fastness to transfer in joints, appearance after washing, water-vapour permeability rate, residual metal needles, and anti-pile properties of down garments. The appearance quality includes surface defect, specification and dimension deviation, dimensional difference at symmetric parts, raw materials and sewing requirements.
5.1.2 For items not mentioned but required by national mandatory standards, the national mandatory standards shall prevail.
5.2 Grade classification requirements
5.2.1 The products are classified into superior products, first-grade products and acceptable products in terms of the quality grade.
