For rack-component-level testing, your best bet is our quality temperature/humidity chambers ;Faster Temperature Cycling Chambersmodels. For fully loaded racks, a walk-in chamber is needed.
Paragraph | Title | Description | Benchtop Models | Reach-in Models | Other Models |
---|---|---|---|---|---|
5.1.1.1 | Low-Temperature Exposure and Thermal Shock | Hold the equipment at -40°C for 72 hours, then remove to ambient room temperature | Almost every benchtop | Any quality temperature/humidity chambers | Walk-in |
5.1.1.2 | High-Temperature Exposure and Thermal Shock | Hold the equipment at 70°C for 72 hours, then remove to ambient room temperature | Any benchtop or ovens | Any quality temperature/humidity chambers or Faster Temperature Cycling Chambers | Walk-in |
5.1.1.3 | High Relative Humidity Exposure | Maintain 40°C and 90-95% RH for 96 hours, with controlled heat-up and cool-down | Any humidity model | Any quality temperature/humidity chambers | Walk-in |
5.1.2 | Operating Temperature and Relative Humidity | There are 14 steps to the test sequence, cycling from -5 to 50°C, as well as humidity. One step requires holding 5°C/<15%RH. | Any quality temperature/humidity chambers | Walk-in | |
5.1.3 | Operating Altitude | Twelve step cycling test of temperature and humidity. 25°C to 50°C and up to 4,000 meters above sea level. | Altitude or Walk-in | Walk-in |
Because 5.1.2 and 5.1.3 require your equipment to be operating, these become a challenging application for a test chamber due to the heat generated.
The altitude test is new for Issue 2 of this specification.
