GB/T 31415-2015 "Paints and varnishes—Performance requirements for protective paint systems for offshore and related structures" specifies the core performance indicators for protective paint systems used in offshore and related structures, tailored to the harsh marine environment characterized by high salt spray, strong ultraviolet radiation, and high humidity. The standard covers requirements such as salt spray corrosion resistance, adhesion, impact resistance, and low VOC content. Testing requires the use of instruments such as fully automatic salt spray test chambers, ultraviolet aging test equipment, gas chromatography-mass spectrometry systems, and electromagnetic compatibility testing systems. This provides a unified basis for the design, construction, and quality inspection of coatings, ensuring long-term protective effects for marine engineering structures.
