Introduction of GB 50046-1995

1.0.1 This code is formulated to prevent or reduce corrosion of corrosive medium to building and structure, and make anticorrosion design of industrial construction achieve state-of-art technology, economical rationality, safety and suitability and guarantee quality. 1.0.2 This code is applicable to anticorrosion design of industrial building and structure under action of corrosive medium; and it is not applicable to corrosion caused by stray current. 1.0.3 Anticorrosion design of building shall keep prevention first, comprehensively consider anticorrosion measures according to corrosiveness, ambient condition, production, operation, control level and repair condition, through adjusting measures to local conditions and carrying out different measures for difference. Protection shall be strengthened for location has great influence to production, locations endanger personal safety and difficult to be repaired, as well as important supporting member. 1.0.4 Not only the requirements about anticorrosion design of building stipulated in this code, but also those in current relevant ones of the nation shall be complied with.
