GB/T 5209-1985 "Paints and varnishes--Determination of resistance to water--Water immersion method"

The GB/T 5209-1985 standard specifies the method for the determination of water resistance of Paints and varnishes based on the international standard ISO 1521-1973. This method evaluates the water resistance of the paint film in the condensed water environment through immersion testing, and determines its water resistance by accelerated testing. This standard applies to the inspection of the durability of coatings under wet conditions.
