Summary for non-condensing humidity cabinet Discussion
Non-condensing humidity cabinet standards are not identified in the thread as a specific ASTM equipment specification. Eloy Frias asked whether any standard exists for a non-condensing humidity cabinet, and Cindy Cynthia L. Meade replied that the term usually means a cabinet operating at less than 95% relative humidity, or one where condensation forms on the cabinet walls rather than on the samples, as in ASTM D2247. She added that there are many humidity tests, including ASTM D2247, ASTM D1735, ASTM B380, and GM4465P, but she was not aware of a standard for the cabinet itself. A later question from Deepesh Gupta asked how 95% non-condensing humidity is measured, but no answer is shown in the excerpt.
Q. To whom it may concern:
I would like to know if there are any standards (ASTM or any other) for a non-condensing humidity cabinet. I have searched the ASTM Website as well as web searches with no luck. I would appreciate any help.

A. Eloy – The term “non-condensing” usually refers to a cabinet that operates at less than 95% relative humidity. It also can mean a cabinet in which the condensation forms on the walls of the cabinet, rather than the samples (such as ASTM D2247). There are a number of humidity tests, but I am not aware of any specification for the equipment itself. Commonly-used humidity tests are ASTM D2247,
ASTM D1735, ASTM B380, GM4465P, etc.
