NOTE. Specified load does not include the weight of the bag body.
5.3.1.3 Oscillation impact
According to the load specified in Table 5, the load is evenly placed in the case (bag). Test the strap, carrying handle, side carrying strap in the order of QB/T 2922. The numbers of oscillation impact are as follows. 400 times respectively for double straps, double-carrying handle; 250 times respectively for single- strap, single-carrying-handle; 150 times for side carrying strap.
The carrying handle (strap) with a total length of less than 120 mm does not check the oscillation impact performance. Simple stacking package does not check oscillation impact performance.
Perform test according to the followings.
- when testing the strap, adjust the strap to the maximum length;
- when testing double straps and double handles, two straps or two handles shall be fixed on the special fixture of the bag oscillation impact tester at the same time;
- when the replacement kit is attached to the handbag and knapsack, select the longest part to test;
- when the handbag and knapsack has components that can be changed in
use (for example, the same component can be used as a single strap and
a double strap or a double handle), and the test shall be performed in such a manner that the maximum load and the number of oscillation shocks are specified;
- when the suture parts of double straps and the single handle of the handbag and knapsack are overlapped, the single handle shall not check the item; - if the handbag and knapsack is in the form of dual bag in bag, the attached bag has a completely independent structure, components (with handles
and/or straps), function, and can be used as a back bag alone, the
oscillation impact inspection shall be performed.
NOTE 1. Double straps and double handles refer to the same components in the corresponding symmetrical part of the product.
NOTE 2. The total length of the handle (strap) refers to the length of the outline of the uncovered portion of the handle (strap).
5.3.2 Lock durability
5.3.7 Color fastness to rubbing
Test according to the followings.
- top layer material. sampling on the large side of the handbag and knapsack and on the cover to check the color fastness; when the front large surface, the rear large surface, and the cover are the same material (the materials, colors, and styles are the same), the large surface shall be sampled and tested; when the front large surface, the rear large surface, and the cover are made of different materials, they shall be sampled and tested
separately; when the front large face and the cover are the same material, the front large face or cover shall be sampled and tested;
- lining. sampling from the main material in the bag, only testing the dry wiping.
Leather, recycled leather, artificial leather/synthetic leather fabrics are inspected according to QB/T 2537. The mass of glossy leather test head is 1000 g, the suede test head is 500 g. Dry wiping 50 times, wet wiping 10 times. Fur fabrics are inspected according to QB/T 2790. Fabric and uncoated microfiber material are according to QB/T 3920. Take 1 set of samples for inspection, in which uncoated microfiber material uses rectangular friction head.
Samples for measuring the thickness of the surface coating shall be measured according to GB/T 22889.
5.3.8 Corrosion resistance of hardware accessories
Inspect according to QB/T 3826 (excluding pull rod, riveting parts, metal fasteners). The zipper head only detects the pull tab, and the test time is 16 h. 5.3.9 Strap folding resistance
Inspect according to QB/T 5246. Test 500 times.
