2. coating and plating test

Automobile coatings, which are used in the coating of automobile body and parts, play an important role in anticorrosion, prolonging service life and elegant appearance of automobile body and parts, and are an important part of automobile materials. Its main testing items are:

Basic properties of paint: dry time, dry time, covering power, fineness, viscosity, etc.

Physical properties of finished products: coating thickness, coating hardness, adhesion, bending strength, cupping test, color difference, gloss, metallographic analysis, porosity;

Reliability performance of finished products: friction resistance, scratch resistance, water resistance, chemical medium resistance, high and low temperature aging, xenon lamp aging, high pressure washing, gravel impact, ball impact.

3. reliability testing

Reliability testing is to simulate the various environments that the product may encounter in the course of use to accelerate the aging of the sample, so as to verify whether the product meets the design requirements. Reliability tests include:

Climate reliability: high and low temperature aging, temperature and humidity cycle, cold and heat shock, xenon lamp aging, UV aging, carbon arc lamp aging, salt spray test, dust and waterproof test, gas corrosion, ozone aging, anti-mold test;

Mechanical reliability: vibration test, mechanical impact, mechanical impact, drop test, ball impact, button life test;

Flame retardant properties: automotive interior combustion, horizontal vertical combustion, hot wire, needle flame, furniture flame retardant testing.

4.VOC test

VOC is an English abbreviation for Volatile Organic Compounds, mainly including alkanes, olefins, aromatic hydrocarbons and aldehydes and ketones, many of which are high-risk substances. When the concentration of VOC in the air inside the car is too high, it will do harm to the human body, and even damage the liver, kidney, brain and nervous system. VOC testing has become the most concerned testing item for the host factories and consumers.

5. detection of harmful substances

In order to protect the environment, reduce the waste generated by vehicle scrap and improve the recycling efficiency of scrap vehicles, the European Commission and the European Parliament issued directives 2000/53/EC and 2005/64/EC on 18 September 2000 and 26 October 2005 respectively, which restrict the content and use of harmful substances in all vehicle parts and materials.
