The luggage Sternum Strap Adjuster mainly has the following three aspects in the testing process:

The first is temperature test: this is mainly to test the bearing capacity of luggage fasteners at unconventional temperatures, which are divided into two types: high temperature and low temperature:
1. The high temperature is usually set at 70 degrees Celsius.
2. The low temperature is usually set at minus 30 degrees. The time was 24 hours and then the change in intensity was tested.
In addition, in the case of acid resistance test, etc., appropriate values ​​can be checked according to needs and materials. Among them, the metal luggage fasteners are also inspected for rust, corrosion, and chemical resistance. If the metal luggage buckle has post-processing procedures such as electroplating, water dyeing, and oiling, it is necessary to further test whether these additional procedures are qualified.
The last is the tensile test: this test is mainly to detect the bearing capacity of the luggage fastener, which is divided into two steps to complete:
1. Regarding the bag fasteners, there is also the detection of the number of times of use. It is constantly opened and closed to test how many times the bag fasteners will be deformed.
2. Instant tension test, mainly used for buckle, D buckle, sun buckle, to test the strength of the bag Stenum Strap Adjuster when suddenly encountering strong pulling force.
3. Durable tensile test, its main principle is to determine the time value of the luggage fastener when a certain weight is loaded.
