Non-condensing humidity cabinet standards [Illinois] 

++

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.

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 [link is to info about spec at TechStreet], D1735 [link is to info about spec at TechStreet], B380, GM4465P, etc.
