How to inspect the bags
As early as 2005, China's total export volume of luggage and bags exceeded 7 billion US dollars, accounting for nearly 70% of the total import volume of developed
regions such as Europe and The United States. The prosperous business of luggage and bags means that the inspection and testing market of luggage and bags is also huge
So, for a package product, what inspection and testing items to go through
Case and bag testing items are mainly divided into three categories:
Category A: general product assessment items;
Category B: high quality product assessment items (including Category A items and below);
Category C: high quality product assessment items (including Category B items and other items below)
Class A luggage detection items:
1 process level: Check whether there is any bad design or component that will harm the user during use.
2 Roller handle performance: set the load of the case and bag in normal use, and investigate the anti-fatigue degree of the roller after a long time of rolling, as well as the strength and durability of the handle shoulder strap
Class B high quality luggage inspection items:
Static load test:
1 set beyond normal load bearing weight, under the condition of test in a stationary state of suspension handle the intensity of the shoulder straps
2 handle the dynamic strength of the load test: can simulate shake handshandle in bags bearing situation, when use the intensity of the situation as luggage handle in the lift repeatedly, put down the process, can reflect the damage of materials and the structure of the shake handshandle of bad design
Class C High quality suitcases and bags testing items
1 drop test: normal bearing samples of bags in one highly free fall drop the corresponding number, check the status of damaged
2 extrusion test: simulation bags squeezed in the process of transport or storage conditions of
3 bars of durability test: simulation of the rod rises down process, check the lever mechanism of resistance to fatigue
other items:
1 box aspects: structural stability testing of material physical properties: cloth gram weight, fabric and leather friction color fastness to light, lock zipper puller shoulder seam fastness
3 materials chemistry performance: can release carcinogenic aromatic amine azo dye test, formaldehyde content, total cadmium content, hexavalent chromium test
4 accessories: metal parts resistant to corrosion, zipper open and the durability of the test, locks open and durable performance tests, the magic for shear, to tear away from strength, durability
Specification for performance testing of some cases and bags:
1. Rod box: the inspection items of the hard box must include appearance quality, specification, identification mark and physical and mechanical properties;
Physical and mechanical properties include fatigue resistance, walking performance, oscillating impact performance, impact resistance, static pressure resistance of the hard box body, impact resistance of the hard box face to falling ball, zipper tensile strength, surface hardness of the aluminum mouth of the box, box lock, corrosion resistance of hardware accessories.
The required inspection items of the soft box include appearance quality, specification, identification mark (material identification) and physical and mechanical properties;
The physical and mechanical properties shall include fatigue resistance, walking performance, oscillation impact performance, impact resistance, zipper tensile strength, stitching strength, box aluminum surface hardness, box (bag) lock, corrosion resistance of hardware accessories, color fastness to friction (dry) and color fastness to friction (wet).
2. Back bag: the required inspection items include appearance quality, specification, identification mark (material identification) and physical and mechanical properties;
The required items of physical and mechanical properties include oscillating impact performance, suture strength, fittings, zipper durability, corrosion resistance of hardware fittings, color fastness to friction (dry) and color fastness to friction (wet).
3. Ticket folder: required items include identification, material identification, appearance quality and sewing requirements, physical and mechanical properties;
The physical and mechanical properties of the required items include the quality of accessories, zipper durability, color fastness to friction (dry), color fastness to friction (wet).
Note: Leather and fur bags: formaldehyde content and azo dye must be tested.
Testing standard
Among the industry standards, the "bags" involved in the current leather industry standards are listed in the "leather" category, mainly referring to travel bags and bags and various back bags
There are 6 categories related to cases and bags in the classification:
QB/T 1332-91 document box
QB/T 1333-2004 Carry bag
QB/T 1585-92 Household trunks
QB/T 1619-2006 Leather ticket folder
QB/T 2155-2004 Travel bags
QB/T 2277-96 Portfolio
