    Bags and Suitcases inspection involves three categories:
    A: General product assessment
    B: Quality product assessment (contain class A and below)
    C: Premium product assessment (contain class B and below)

    ■ Class A bags and suitcases testing items
    1 Level of the Process inspection.
    2 Roller and handle performance inspection: under normal used load conditions, bags and suitcases are detected the anti-fatigue of idler wheel after a long time rolling, and strength and durability of handle and shoulder strap.

    ■ Class B Good bags and suitcases testing items
    1 Static load test: beyond normal used load conditions, strength of handle and shoulder strap is detected while good bags and suitcases are suspended at rest.
    2 Test for dynamic strength load of handles: The strength of the handle can be simulated when the bag is under load and in use. For example, if the handle is repeatedly pulled up and down, it will reflect the damage of materials and the poor design of handle structure.

    ■ Class C Premium bags and suitcases test items
    1 Drop test: The numbers of normal load-bearing premium bags and suitcases falling down from a certain height are detected to check for damage.
    2 Extrusion test: To simulate the case of being squeezed of cases and bags during transportation or storage.
    3 Durability test of the pull rod: The pull rod is simulated to be raised and laid down to detect the durability.

    ■ Other inspection items
    1 Bags and suitcase bodies: Structural stability test.
    2 Physical properties of material: Weight of fabric, friction between fabric and leather, light fastness, thread fastness of lock, zipper, handle and shoulder strap
    3 Chemical properties of material: Testing of azo dyes that release carcinogenic aromatic amines, formaldehyde content, total cadmium content, and hexavalent chromium.
    4 Accessory: Corrosion resistance of metal parts, durability test of zipper opened and closed, durability test of lock opened and closed, shear force, tear force and durability of Velcro.

    ■ Specification for performance testing of bags and suitcases
    1. Trolley suitcases: hard suitcase checking items include appearance quality, specifications, identification marks (material identification) and physical and mechanical properties, which contains fatigue resistance of pull rods, moving performance, oscillating impact performance, impact resistance, hard-case box resistance to static pressure performance, impact resistance of hard-case surface for drop ball, pulling strength of zipper, surface hardness of aluminum part, locks, hardware accessories corrosion resistance. Soft suitcase checking items include appearance quality, specifications, identification marks (material identification) and physical and mechanical properties, which contains fatigue resistance of tie rods, moving performance, oscillating impact performance, impact resistance, pulling strength of zipper, surface hardness of aluminum part, lock, hardware accessories corrosion resistance, color fastness to rubbing (dry), color fastness to rubbing (wet).

    2. Back-pack and handbag: should check appearance quality, specifications, identification marks (material identification) and physical and mechanical properties, which include oscillating impact performance, suture strength, accessories, zipper durability, hardware accessories corrosion resistance, color fastness to rubbing (dry), color fastness to rubbing (wet).

    3. Leather wallet: should include identification marks, material identification, appearance quality and sewing requirements, physical mechanical properties including accessories quality, zipper durability, color fastness to rubbing (dry), color fastness to rubbing (wet).
    Note, suitcases and bags made from animal leather and fur must carry out tests of formaldehyde content, AZO dyes.

    Test standard:
