Humidity Cell Testing. Humidity cell tests are designed to mimic weathering at the laboratory scale in a controlled fashion The test determines the rate of acid generation the variation over time in leachate water quality and thus allows you to develop mitigating strategies The standard humidity cell test is conducted at the bench scale.

Humidity cell tests (HCTs) are longterm (20 to >300 weeks) leach tests that are considered by some to be the among the most reliable geochemical characterization methods for estimating the leachate quality of mined materials A number of modifications have been added to the original HCT method but the interpretation of test results varies widely.

PDF fileStandardized Testing of Materials has proposed a standard procedure for humidity cells6 that involves trickle leaching of a sample and other steps that would preclude the reliable removal of accumulated reaction products Also many column tests are operated and interpreted like cells where the ongoing retention of reaction products as secondary.

The cell temperature was measured with the DS18B20 temperature sensors attached to the rear side of the encapsulated cells Ambient temperature relative humidity and precipitation were measured with a meteo station (CLIMA SENSOR US.
