China is already a big country of luggage production. In 2005, the total export volume of bags and bags exceeded 7 billion US dollars, accounting for nearly 70% of the total imports of developed countries and regions such as Europe and the United States.

Luggage inspection items are mainly divided into three categories:

Class A: general product assessment items

Class B: higher quality product assessment items (including class A and below)

Class C: product assessment items (including category B items and other items below)

Class a luggage inspection items

1. Process level: check whether there are bad designs or components that are harmful to users in use.

2. Performance of roller and handle: set the load of luggage in normal use, and investigate the anti fatigue degree of roller after rolling for a long time, as well as the strength and durability of handle and shoulder strap.

Class B high quality luggage inspection project

1. Static load test: the strength of handle and shoulder strap is tested when the load exceeds the normal load.

2. Dynamic strength load test of handle: it can simulate the strength of handle in the case of load-bearing of bags and in use. If the bag handle is repeatedly lifted and put down, it will reflect the damage of materials and the bad design of handle structure.

Class C luggage inspection project

1. Drop test: normal load-bearing luggage samples fall freely at a certain height for corresponding times, and check the damage.

2. Extrusion test: simulate the extrusion of bags 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.

1. Box: structural stability test.

2. Physical properties of materials: weight of cloth, friction and light fastness of cloth and leather, seam fastness of lock, zipper, handle and shoulder strap.

3. Chemical properties of materials: azo dyes that can release carcinogenic aromatic amines, formaldehyde content, total cadmium content, hexavalent chromium test.

4. Accessories: corrosion resistance of metal parts, durability test of zipper opening and closing, opening and closing durability test of lock, shear force, tear off force and durability of Velcro.

Specification for performance testing of some cases and bags

1. Trolley Case: the required inspection items of hard case include appearance quality, specification, identification mark and physical and mechanical properties; among them, the required physical and mechanical properties include fatigue resistance, walking performance, oscillating impact performance, impact resistance, static pressure resistance of hard box, drop ball impact resistance of hard box surface, flat pull strength of zipper, surface hardness of aluminum port of box, box lock and hardware fittings corrosive. The required inspection items of soft box include appearance quality, specification, identification mark (material identification) and physical and mechanical properties; among them, the required physical and mechanical properties include fatigue resistance, walking performance, oscillation impact performance and impact resistance of the pull rod Performance, zipper pull strength, sewing strength, surface hardness of aluminum mouth, case (bag) lock, corrosion resistance of hardware accessories, color fastness to rubbing (dry), color fastness to rubbing (wet).

   
   

2. Carry bag: the required items include appearance quality, specification, identification mark (material identification) and physical and mechanical properties; among them, the required physical and mechanical properties include vibration impact performance, sewing strength, accessories, zipper durability, corrosion resistance of hardware fittings, color fastness to rubbing (dry) and color fastness to rubbing (wet).

3. Ticket holder: the required items include identification mark, material identification, appearance quality and sewing requirements, and physical and mechanical properties; among them, the required items in physical and mechanical properties include accessory quality, zipper durability, rubbing color fastness (dry) and rubbing color fastness (wet).

Remark: leather and fur bags: formaldehyde content and azo dye must be detected.

In the industry standards, the "bags" involved in the current leather industry standards are listed in the category of "leather goods", mainly referring to travel bags and various kinds of carrying bags.

In the classification, there are 6 categories related to bags

QB / T 1332-91 briefcase

QB / T 1333-2004 Backpack

QB / T 1585-92 household suitcase

QB / T 1619-2006 Leather Wallet

QB / T 2155-2004 luggage

QB / T 2277-96 briefcase
