一九七六年由日本防锈技术协会和腐蚀防蚀协会共同组织了《日本腐蚀损失调查委员会》,对日本的防腐费用进行调查研究,并于1977年写出了调查报告。腐蚀损失是指由于腐蚀事故产生的直接损失(材料更换费,维修作业费)及其防腐费用,不包括间接损失(由腐蚀事故造成的仃工减产)在内。而间接损失往往比直接损失要大得多. In 1976, Japan Society of Corrosion Protection and Corrosion Prevention Association co-organized the “Japan Corrosion Loss Investigation Commission” to examine Japan’s anti-corrosion costs, and in 1977 wrote a survey report. Corrosion loss is the direct loss (material replacement fee, maintenance fee) and its preservation costs incurred as a result of a corrosion accident, excluding indirect losses (loss of production caused by corrosion accidents). Indirect losses are often much larger than direct losses.
