Field Test of Irreversible Humidity Indicator.

Abstract

The objective of this report was to determine the effectiveness of irreversible relative humidity (RH) indicators in the storage environment of DOD organizations throughout the Continental United States (CONUS). Twelve DOD organizations participated in a twelve month field test of irreversible RH indicators which were installed in a various types of containers with a variety of items. The indicator, which turns to a dark orange/brown color after exposure at 55% RH, will not reverse (even in a dry environment) as do the blue (low RH)/pink (high RH) reversible types. The reversible type can be affected by temperature/sunlight without an actual change in humidity. The test revealed that the indicator will provide a positive and permanent indication of early stage moisture intrusion before corrosion takes place. Additionally, the test revealed that 12% of test containers with actual stored items indicated a RH above 55% even though the blue/pink reversible reference elements indicated RH levels below 50%.
