GTS authoritative testing and certification laboratory automotive parts luggage rack fast and low-cost testing

Automotive materials and parts

Provide various kinds of automotive materials and parts inspection certification

Automobile is an electromechanical hybrid system composed of tens of thousands of parts. Auto parts inspection can help auto manufacturers and parts manufacturers get detailed reports on the quality of parts, so as to improve the performance of parts.Testing covers environmental reliability testing of auto parts,Electrical performance test, functional test, EMC test,Material testing, green environmental testing and chemical compliance services.

Rack is so widely used in the car, in addition to play the role of decoration, beautiful, it can put the luggage compartment can not put things, such as large size bags, bicycles, folding bed, etc., as long as the cargo owner fixed in place, especially on the goods with luggage rope on the net, it can carry more stuff than you expected. Of course, it cannot exceed the designed load-bearing capacity of the luggage rack. Therefore, whether the luggage rack can meet the specified design standards must be verified by testing.
