Telecordia 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.
