GB/T 13351-1992 "General technical conditions for ship bottom anti-rust paint" is a non-equivalent national standard using NFJ17-201, which stipulates the general technical requirements for ship bottom anti-rust paint. The content covers product classification (such as asphalt, chlorinated rubber, etc.), technical indicators (adhesion, drying time, saline water resistance, anti-rust performance, etc.), test methods (film preparation, saline water immersion test, etc.), inspection rules and Encasement storage requirements. This standard applies to the production and quality control of anti-rust coatings on the bottom of ships. By standardizing the corrosion resistance performance and construction adaptability of anti-rust paints, it ensures that the bottom metal substrate is free from rust in the marine environment. Provide technical basis for the selection, production and inspection of marine anti-rust paints, and help improve the protection performance and service life of ships.
