Leather box inspection

Project background: China is already a major country in luggage production. In 2005, the total export value of luggage exceeded 7 billion US dollars, accounting for nearly 70% of the total import volume in developed and regional regions such as Europe and America. The luggage inspection items are mainly divided into three categories: Class A: General product assessment items; Class B: High quality product assessment items (including Class A items and below); Class C: Product assessment items (including Class B items and below); Class A luggage inspection items. 1. Process level: Check whether there are defective designs or components that pose a threat to users during use. 2. Performance of rollers and handles: Set the load conditions of the luggage during normal use, examine the fatigue resistance of the rollers after long-term rolling, as well as the strength and durability of the handles and shoulder straps. Class B higher quality luggage inspection item 1. Static load test: Set the load to exceed the normal carrying capacity, and test the strength of the handle and shoulder strap in a static suspension state. 2. Dynamic strength load test of the handle: It can simulate the strength of the handle during use under the load bearing condition of the bag. If the luggage handle is repeatedly lifted and lowered, it will reflect the damage of the material and the poor design of the handle structure. Category C luggage inspection item 1. Drop test: Normal load-bearing luggage samples fall freely at a certain height for a corresponding number of times to check for damage. 2. Squeezing test: Simulate the situation of a bag being squeezed during transportation or storage. 3. Durability test of the pull rod: Simulate the process of lifting and lowering the pull rod, and check the fatigue resistance of the pull rod mechanism. Project background 1. Box aspect: Structural stability testing. 2. In terms of material physical properties: fabric weight, friction between fabric and leather, color fastness to light, and seam fastness of locks, zippers, handles, and shoulder straps. 3. In terms of material chemical properties: azo dye testing that can release carcinogenic aromatic amines, formaldehyde content, total cadmium content, and hexavalent chromium testing. 4. In terms of accessories: corrosion resistance of metal parts, durability testing of zipper opening and closing, durability testing of lock opening and closing, shear force, tearing force, and durability of Velcro. Part of the performance testing specifications for luggage: 1. Trolley boxes: The mandatory inspection items for hard boxes include appearance quality, specifications, identification marks, and physical and mechanical properties; The required physical and mechanical properties include the fatigue resistance, walking performance, oscillation impact performance, impact resistance, static pressure resistance of the hard box body, drop ball impact resistance of the hard box surface, zipper pulling strength, surface hardness of the aluminum mouth of the box, corrosion resistance of the box lock and hardware accessories. The mandatory inspection items for soft boxes include appearance quality, specifications, identification marks (material identification), and physical and mechanical properties; The required physical and mechanical properties include the fatigue resistance, walking performance, oscillating impact performance, impact resistance, zipper pulling strength, stitching strength, surface hardness of the aluminum mouth of the box, corrosion resistance of the box (bag) lock, hardware accessories, color fastness to friction (dry), and color fastness to friction (wet). 2. Backpack: The required inspection items include appearance quality, specifications, identification marks (material identification), and physical and mechanical properties; The mandatory items in the physical and mechanical properties include oscillation impact performance, stitching strength, accessories, zipper durability, corrosion resistance of hardware accessories, color fastness to friction (dry), and color fastness to friction (wet). 3. Ticket holder: mandatory items include identification marks, material identification, appearance quality and sewing requirements, and physical and mechanical properties; The mandatory items in the physical and mechanical properties include accessory quality, zipper durability, rubbing color fastness (dry), and rubbing color fastness (wet)
