Why does HALT only use Temperature and Vibration? Why isn humidity used?
If humidity testing is a requirement for a product design, it should be performed separately. Humidity is considered to be a very weak stress for electronic and electro-mechanical systems. Humidity testing is also a longer-term test and may only begin a process that results in defects occurring much later. Humidity testing is only practical at temperatures above 0 degrees C.
- During the warmer months, the relative humidity is given together with the temperature displayed on television. When is the relative humidity used, and how is it calculated?
- About the radiometer, how brightness temperature is defined, and why 3 frequencies are used?
