GR-487-CORE for enclosures

Your best bet for a single chamber to do all these tests is our Platinum series.

Paragraph Title Description Benchtop Models Reach-in Models Other Models
3.26 R3-187 C. Simulation of High Ambient Temperature 46°C Any benchtop or PH or PV ovens Any Platinous or Platinum Walk-in
3.27 R3-191 [155] Thermal Shock -40 to 60°C Almost every benchtop Any Platinous or Platinum Walk-in
3.34.2 R3-204 [166] Temperature Cycling/High Humidity 4 to 60°C w/ RH (see below) ENX Walk-in


Here is a summary and special note of 3.34.2: Corrosion Resistance- Temperature Cycling/High Humidity:

Requires 40 twelve-hour cycles with three hour soaks at each extreme. Ramping up from 4.4 to 32°C with 90-95%RH, between 32 to 60°C, a specific humidity of 0.024 kg of water per kg of dry air. During descending temperatures—32 to 4.4°C humidity should be held to 80-95%RH.

ESPEC notes that maintaining humidity during temperature ramping is dependent on the test chamber, the way the cycle is programmed, and the samples loaded. A special modification to the humidity system may be required. Please let us know if you are going to be doing this test.
