<P>PROBLEM TO BE SOLVED: To provide a method which quickly performs management and analysis/evaluation of the degree of staining by attached substances attached to an electric appliance and performs highly accurate analysis/evaluation. <P>SOLUTION: The analysis/evaluation method for the degree of staining by attached substances attached to an electric appliance extracts water soluble ionic components of the attached substances by pure water, obtains equivalent chloride ions by making at least either sodium chloride, sodium sulfate, or sodium nitrate a graph by measurement of electricity conductivity, extracts water soluble ionic components of the attached substances by pure water, performs a quantitative analysis by an ion chromatography method to obtain chloride ions contained in the ionic components, and obtains a total chloride ions combining the equivalent chloride ions and the chloride ions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
