The "Test and Evaluation Method for Ultraviolet Penetration Resistance of Automobile Coatings" was proposed by the Automobile Anti-corrosion and Aging Branch of the Chinese Society of Automobile Engineering and approved by the Chinese Society of Automobile Engineering. This standard is under the jurisdiction of the China Automotive Engineering Society. This version is a draft for soliciting comments on changing the test method, for reference only.
1 Scope
This standard specifies the testing and evaluation methods for the UV penetration resistance of single or composite coatings on automobile bodies.
This standard applies to the process verification and material development process of automobile body coating process. The testing and evaluation process of Haotian's other coating systems that have requirements for UV penetration can also refer to the test and evaluation process of UV penetration resistance.
