Test items:

Reference standard item note 1: The specifications are measured using a steel tape measure or a special ruler with a pision value of 1m.

. 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. Decomposable and carcinogenic 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. 4. The limit of harmful substances in luggage adhesives mainly includes benzene, toluene, xylene, n-hexane, TVOC, etc. 12. Appearance quality includes requirements for overall, surface material, suture, accessories, zippers, components, standard samples, etc. 13. Fatigue resistance of pull rods; The main test is to check whether the pull rod of the travel bag is deformed, stuck, or loose after the test. 14QB/T 2920 walking performance; Mainly testing the flexible rotation, no jamming, and no deformation of the running wheel after the test: no deformation of the wheel frame and axle, and the oscillation impact performance of the 15QB/T 2922 open cover; The main test is to ensure that the box (enclosure) does not deform or crack after the test; All components shall not deform, break or be damaged. The drop performance of 16QB/T 2921 is mainly tested, and after the test, the box body, box mouth, and village frame shall not crack, and dents are allowed; The wheels, axles, and brackets are not broken. 17. The static pressure resistance performance of the hard box body is mainly tested. After the test, the box mouth is not deformed or cracked, and the box shell is not trapped on the wall. The opening and closing are normal. 18QB/T 2918. The plastic hard box surface is resistant to falling ball impact. After the test, the pin surface is not cracked. 19QB/T 4916. The roller impact performance is mainly tested. After the test, the box body, box mouth, and village frame are not cracked, and dents are allowed, Allow 20 boxes (bags) with surface scratch resistant and thin clothing to be damaged. Durable performance of box (bag) locks. The box (bag) lock can be opened and closed normally without any abnormalities. 21GB/T 231.1 box aluminum mouth hardness requirement ＜ 40HWB22 seam strength test. Use a tensile machine to test the seam strength of the main parts of the travel bag until it breaks. 23QB/T 2537, QB/T  2790, GB/T 3920, GB/T 22889 Friction Color Fastness (Staining)/Grade refers to the resistance of a material's color to various effects during processing and use. 26QB/T 3826 Hardware Accessories Corrosion Resistance The ability of metal materials to resist the corrosive damage of surrounding media is called corrosion resistance.
