Former researches on cost of corrosion in Japan

わが国における過去の腐食コスト調査

山本 正弘 

Yamamoto, Masahiro

わが国においてこれまで2回にわたり腐食コスト調査が実施された。1回目の調査は1975年に腐食防食協会と防錆技術協会が共同で実施し、腐食による経済的な損失がGDPの1.8%にもなることが報告された。その後4半世紀を経た1998年に2回目の腐食コスト調査が実施された。この間に我が国の経済事情は大幅に変化し、腐食コストにもその影響が表れた。本報告ではこれら2回の腐食コスト調査の内容を概説する。

The committee surveying the corrosion losses in Japan was established in 1976, with conjunction of the Japan Society of Corrosion Engineering and the Japan Association of Corrosion Control. The report made by the committee introduced that corrosion loss was estimated to be about 1.8% of GDP (Gross Domestic Product). About quarter century had passed after the first survey, JSCE and JACC made the second surveying committee for the cost of corrosion in Japan in 1998. During that time, Japan's economic circumstances had changed drastically. In this report, results and problems of the former two researches are summarized.
