For research calendar life of metal, this paper through theoretic analysis and test research, a line with equal humidity, teperature and time of metallic corrosion is found out, which presents a straight line in d coordinate system of corrosion damage and solution concentration. Each point on this straight line, known as "3 equal-line", has equal corrosion test humidity, temperature and time. The formula of service calendar life and determination method of the test are deduced from the research of the "3 equal-line" and other comprehensive research. Meanwhile, we also carry out test to verify the linear regularities of corrosion damage and corrosion time as well as the existence of the "3 equal-line".
