GB/T 1733-1993 《Determination of resistance to water of films》 Related products

The standard GB/T 1733-1993 "Method for the determination of water resistance of paint films" specifies a method for evaluating the durability of paint films in humid environments. This standard applies to all types of coatings and varnishes, simulating humid environments under laboratory conditions to determine the resistance of paint films to water. During the test, the sample is exposed to the specified humid conditions for a period of time, and then the film is checked for Appearance changes and performance losses, such as blistering, flaking or Color changes. The purpose of this standard is to provide a standardized test method for evaluating the durability of coatings in humid environments, and to help manufacturers and users of coatings confirm that the mass and performance of products meet the expected requirements.
