The standard was proposed by the Wuhan Institute of Materials of the Ministry of Machinery Industry and stipulates the technical conditions for organic coatings of typical mechanical products in heat and humidity environments. The standard involves the anti-corrosion performance, moisture and heat resistance performance and application methods of organic coatings, aiming to improve the durability of mechanical products in heat and humidity environments. Drafted by the Wuhan Institute of Materials Protection, it ensures the effective protection of coatings in harsh environments.
