The performance characteristics of Irreversible Humidity Indicators were evaluated in a constant temperaturehumidity chamber at various combinations of temperature and humidity conditions. The test results revealed significant information on its actuation threshold value and the degree of influence on the threshold value of these data will provide useful guidelines to field personnel who use the indicators and will also be used to establish requirements in procurement specifications. The purpose of this study was to evaluate the subject indicator under different sets of humidity and temperature conditions to 1 Establish the threshold value at ambient conditions. 2 Determine the effect of temperature and humidity on actuation time. 3 Develop indicator performance characteristics required to establish procurement specifications requirements.
