Inspection items:

Reference standard item note 1 GB/T 3293.1-1998 Shoe 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. 3GB 20400 (leather and fur) QB/T 4108-2010 (metal accessories, fasteners) 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 and upper surface of the sensory quality are free from obvious defects, the toe of the shoe is free from shrinkage and deformation, the heel is symmetrical in height, the stitching is neat and without detachment, and the accessories are firm, The size deviation is within the standard requirement range of 6GB/T 3903.3-2011. The peeling strength of the upper or the peeling strength of the bottom wall and upper is the main indicator of the adhesion fastness between the upper and outsole. Shoes with unqualified peeling strength of the upper and sole are prone to problems such as opening and cracking during wearing. Tourism shoes with shoe sizes less than 230mm and a thickness of more than 25mm in the flexure area of the sole are not tested for folding resistance according to 7GB/T 3903.1-2008. Other tourist shoes must not have cracked upper after 40000 folds; Bottom wall, upper sole, and sole adhesive opening ≤ 5.0 mm; After folding, there should be no more than 3 cracks on the sole, and the longest crack length should be ≤ 5.0mm; The sole of the shoe shall not show any color peeling off; Shoes with air (liquid) pads should not experience deep air (liquid) or collapse after folding. 8GB/T 3903.2-2008 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. 9QB/T 2224-2012 Low temperature bending of upper material (-10 soil 2) C for 30000 times, and there should be no visible fracture of the upper material (including slurry or surface cracking) 10QB/T 2882-2007 Method A: Lining and insole resistance to friction Color fastness refers to the degree of staining of dyed or printed linings and insoles under external factors such as compression, friction, washing and sweat stains during wearing. 11GB/T 3903.4-2008 Outsole Hardness Assessment: The hardness of shoe outsoles should be ≥ 40 Shore A12QB/T 2886-2007. The adhesion strength between the outsole and the midsole should not be less than 20N/cm to avoid problems such as opening and cracking during wearing. 13GB/T 3903.20-2008 (Peel Strength) GB/T 3903.21-2008 (Shear Strength) Buckle Straps - Fatigue Resistance - The quality of the buckle strap after 5000 repetitions of opening and closing under a force of 60 kPa -14. Tourist shoes with a size less than 230mm and a thickness of more than 25mm in the sole flexure area are not tested for bending resistance. After 40000 folds, there should be no more than 3 new cracks with a length of 5.0mm or less. After folding, there should be no cracking, cracking, or adhesive opening on the upper. 15 GB/T17592-2006 (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. GB/T2912.1-2009 (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. The total content of heavy metals in 17QB/T 4340-2012 mainly targets infant and child cloth shoes, as the harm of heavy metals is particularly severe for children. 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< p>
