Telecordia GR-63-CORE for network switching systems (NEBS)



For rack-component-level testing, your best bet is our Platinum models. 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 Platinous 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 PH or PV ovens Any Platinous or Platinum 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 Platinous 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 Platinous 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.
