Testing standard:

Reference standard item identification 1. The difference between the specification size and the length of the double insole should not be greater than 2.0.

; The difference in width should not exceed 1.5 mmn, and the difference in thickness of the same part should not exceed 0.5 mm. There should be no more than 1.0 mm difference in thickness between plush (including felt) insoles. 2GT  3903.5 Sensory quality: The top and bottom layers of insoles should be tightly sealed and not damaged. The same pair of insoles should be symmetrical, without significant color difference (except for special design styles), and the shoe size should be consistent. 3QB/T; 2882 rubbing color fastness refers to the degree of staining of dyed or printed insoles under external factors (such as compression, friction, water washing, sweat stains, etc.) during the wearing process. 4GT  3903.11 Sweat-resistant insole has the ability to resist the action of artificial sweat. The sweat resistance of test materials is usually evaluated by measuring changes in their size and appearance. 5GB/T; The insole made with 532 adhesive strength sewing or adhesive stitching process does not measure the adhesive strength. 6GB/T; 3903.16 Wear resistant sports insoles: dry friction 12  800 times, wet friction 12  After 800 cycles, the sample should not show any wear through, surface layer wear off, or obvious pilling. Children's shoes and non sports insoles: After 12800 rubs and 6400 wet rubs, the sample should not show any wear through, surface layer abrasion or obvious pilling. 7GB/T 17592&Nbsp; GB/T 19942 Decomposable Harmful 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. 8GB/T; 2912.2&Nbsp; GB/T 19941 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 9QB/T 2881 antibacterial performance inner pad uses antibacterial materials or undergoes antibacterial treatment on the surface of the inner pad to make the shoe cavity have antibacterial effect
