Package Testing Using Combined Temperature & Vibration

Package Testing - Combined Temperature & VibrationNowadays 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.

Fastener Vibration Testing

fastener vibration testing servicesDES recently performed fastener vibration testing per MIL standard, MIL-F-25173A.  MIL-F-25173A is a military specification aimed at determining qualification criteria for aircraft fasteners and equipment.  In this case, DES focused on the vibration testing of a particular fastener to be used in aircraft applications.  Tests were conducted on DES’s Unholtz-Dickie Electrodynamic Shaker.  The MIL-F-25173A standard requires specimens to be subject to sinusoidal vibration testing, cycled between 10 and 55 Hz uniformly and with a constant 0.06 inDA displacement.  Tests shall span the course of 90 minutes over three perpendicular axes.
