Qualification Testing on Aerospace Connectors

DES recently performed qualification testing on aerospace connectors which involved combined temperature and sinusoidal vibration testing, random vibration testing and shock testing.  Combined temperature and sinusoidal vibration tests were performed per EIA 364-28F.  EIA 364-28F required test conditions of 10-2000 Hz, 20G maximum acceleration sweeps at temperatures of -54°C and 200°C over the course of 4 hours per axis.  Random vibration tests were also performed per EIA 364-28F.  Random vibrations at 50-2000 Hz, 46.3 Grms were applied to the connectors for 8 hours per axis.  The random vibrations were applied at room temperature.  Finally, the connectors were subjected half sine shocks per…

Package Testing Using Combined Temperature & Vibration

Nowadays global markets and expedited shipping methods expose packages to less than ideal conditions during the transport process.  International Safe Transit Association (ISTA), International Air Transport Association (IATA), International Organization for Standardization (ISO) and American Society for Testing and Materials (ASTM) all contain protocols and requirements used to evaluate product package design.  Some of these test profiles require combined environments such as combined temperature and vibration testing.  This type of testing requires specialized equipment, set up and experience from the lab conducting the test.
