Test Item:

Reference Standard Item Note 1 GB/T 3293.1-1998 Footwear Size Identification includes foot length indication, followed by foot width indication (if required). Both values are expressed as integers in millimeters (without specifying units). Separate each other with a short or diagonal line. The height of the font used should be at least 3mm. 2GT 3293 Shoe Last Size Shoe last is the parent material of shoes. It is the molding mold of the shoe that determines the shape and style of the shoe. Shoe last size refers to a complete set of shoe last sizes that are expanded and shrunk according to the specified size difference, centered around the sample last. 3. Shoe materials include shoe leather, fur, textile materials, metal accessories, etc. The 4QB/T 2673 logo includes trademark, product name, shoe size, material, place of origin, company name and contact information, San Bao regulations, executive standard label, production date, color, and product number 5GB/T 3903.5-2011. The overall appearance of sensory quality, upper surface is free of obvious defects, toe is free of shrinkage deformation, heel height is symmetrical, stitching is neat and without detachment, attachments are firm, and size deviation is within the standard requirements range 6GB/T 3903.3- 2011 Upper sole peeling strength: Upper sole peeling strength is the main indicator of the adhesion strength between the upper and outsole. Shoes with unqualified upper sole peeling strength are prone to problems such as opening and cracking during wearing. 7GB/T 3903.1-1994 Folding resistance of finished shoes: Cloth soles, shoes with shoe sizes below 230mm, and shoes with sole thickness exceeding 25mm are not tested for folding resistance. After 40000 consecutive folding tests on other cloth shoes, there should be no damage to the upper surface, no adhesive opening at the joint of the upper sole, collar, welt, and bottom wall, no delamination of the composite sole, and no detachment of the sole coating layer. There are no new cracks on the outsole, or no more than 3 new cracks, with a single crack length of no more than 5mm. 8GB/T 3903.2-1994 Wear Resistance of Outsoles. Use a wear testing machine and use a rotating steel grinding wheel to wear the flat surface of the outsole for a certain period of time before measuring the length of the wear mark. There should be no wear through or lack of sulfur. It is particularly pointed out that natural leather soles and cloth soles do not measure the wear resistance of the outsole, and baby shoes do not measure the wear resistance. 9QB/T 2882-2007 Method A: Lining and insole rubbing color fastness refers to the degree of staining of dyed or printed linings and insoles under external factors such as compression, friction, water washing and sweat stains during the wearing process. 10GB/T 3903.4-1994 Formed sole sole sole hardness is only tested for sole heights greater than 25mm and does not use inner heels or other reinforcement materials; GB 28011-2011 Steel hook core is a supporting material used to reinforce or prevent bending and deformation at the waistline of shoes. Steel hook core is suitable for shoes with a heel height greater than 20.0mm and a heel opening greater than 8.0mm. 12GB/T 17592-2006 (Textiles) GB/T 19942-2005 (Leather) Content of decomposable and carcinogenic aromatic amine dyes. Decomposable aromatic amine dyes refer to dyes synthesized from carcinogenic aromatic amines, commonly known as "prohibited azo dyes". After decomposable aromatic amine dyes are made into clothes, they cannot be distinguished from the appearance of textiles and can only be detected through technical testing, and cannot be eliminated. This type of dye can cause various malignant diseases and absorb carcinogens when in contact with human skin. 13GB/T 2912.1-2009 (Textiles) GB/T 19941-2005 (Leather) Free or partially hydrolyzable formaldehyde content Formaldehyde is a colorless gas with a pungent odor. Textiles containing formaldehyde will gradually release free formaldehyde during people's wearing process, causing respiratory and skin inflammation through contact with the human respiratory tract and skin, and also causing eye irritation. 14QB/T 4340-2012 Total Heavy Metal Content; Mainly targeting infant and child cloth shoes, as the harm of heavy metals is particularly severe for children. Among them, the total content index of heavy metals: arsenic shall not exceed 100; Mg/kg; Lead shall not exceed 100 mg/kg, and cadmium shall not exceed 100mg/kg
