| Outline of Final Research Achievements |
As a test method of long-term stability of materials used for display and/or storage of cultural heritage, the application of metal thin film sensors at high relative humidity environment without the risk of condensation for the accelerated corrosion test method was evaluated. While in the conventional test condition relative humidity within a test container was kept at 100% almost always during the entire test period and the condensation was occurred at high frequency on metal coupons used for the test evaluation, the application of aqueous glycerol solution allowed to conduct the accelerated corrosion test at high relative humidity below 100% without the risk of condensation, although a strict control of relative humidity value was not achievable. Also the application of metal thin film sensors showed a possibility to conduct the test which gives an objective data on the extent of corrosion and to evaluate the long-term stability of materials.
