There are two important aspects of car development, function and performance. The fatigue durability of a vehicle and its components is an important index for evaluating automobile performance. The test components runs through the process to make a car. Better parts and materials can make better cars.


Main test object

Spare parts:

Automotive exterior components, interior components, electronic and electricity, power battery;


Polymer materials: plastics, rubber, chemical fiber products, coatings, adhesives.

Metallic materials: ferrous metal, nonferrous metal.

Non-metallic materials: inorganic non-metallic, natural materials.

Other materials: chemical products, electrical accessories.

Component environmental reliability test includes:

temperature cycle

light aging test

• gas corrosion

ozone corrosion

• mould test

• random vibration

• sinusoidal oscillation

• impact drop

• three synthetic vibrations


Metal materials:

• physical performance testing

Nonmetallic material:

• wear test

• physical performance testing

• environmental simulation

• coating characteristics


With the continuous development of auto electronic control technology, to increase the number of automobile electronic equipment, various types of electrical and electronic components have accounted for 30% of the vehicle system. Some luxury cars' proportion can even as high as 90%. Can say, the high electronic application make the very big improvement of automobile dynamic performance, safety and economy, and significantly improve the car driving stability and comfort.

So many electronic components need to be tested in the automotive environment, temperature, humidity, vibration, light aging, etc.Car interior belongs to the confined space, when not in use, its temperature can reach 150 degrees under the sun exposure, obviously we human can't exist in this environment, so the test car electronic appliances need to test in extreme climatic. The equipment has a specific higher demands.
