CORROSIVE ENVIRONMENT EVALUATION METHOD BY CORROSIVE ENVIRONMENT SENSOR

摘要

PROBLEM TO BE SOLVED: To solve a problem wherein a corrosive environment is not able to be easily evaluated in a short time, and a problem wherein a corrosive environment is not evaluated precisely because the corrosive environment is difficult to be evaluated in a planned installation place of a steel structure.;SOLUTION: A corrosive environment sensor 1 comprising a plurality of kinds of metal pieces discolored by corrosion factors in the atmosphere related to corrosion of the steel structure is corroded under the environment same to that in the steel structure, then a surface of the corroded corrosive environment sensor 1 is measured by a color measuring means 12 to prepare a color specification data as to lightness, hue and saturation, and the corrosive environment in the place installed with the steel structure is evaluated thereafter using the color specification data obtained from the corrosive environment sensor, and using a color specification master data prepared preliminarily from corrosive environment master data 11a-11f corroded a concentration by a concentration in every corrosion factor.;COPYRIGHT: (C)2006,JPO&NCIPI
