Extreme Combined Temperature & Vibration Testing
DES successfully completed a challenging combined temperature and vibration test which involved high G levels coupled with extreme temperatures! The vibration conditions required for this test were 10 to 2000 Hz, 20G maximum sinusoidal acceleration. These sinusoidal vibration tests were conducted during temperatures of -54°C and 200°C.

MIL-STD-810 Vibration Testing Overview
This is part one of a series of blog posts discussing MIL-STD 810 Vibration Testing. This blog was written with reference to MIL-STD-810G w/Change 1 dated 15 April 2014. DES has the experience and expertise to help you determine what profiles are appropriate for your product and to run your MIL-STD-810 vibration test. Check out our vibration testing capabilities here. MIL-STD-810 is a public military test standard that is designed to assist in the environmental engineering considerations for product design and testing. For the purposes of this blog series we will focus on Method 514.7, titled Vibration. This section defines…
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…
Fastener Vibration Testing
DES 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.
ASTM D7386-12 Package Testing
DES recently performed package testing per ASTM standard, ASTM D7386-12.
Choosing A Vibration Test Lab Part 2
Part 2 – Selecting a Lab and Performing Your Test If you have not done so yet, please check out Part 1 – Defining your project and Obtaining a Quote. You obtained quotes from a couple of vibration test labs. Your next task is to select a vibration test lab to perform your vibration test. Your selection should not be based upon price alone. Factors that should affect which lab you choose are capability, cost, timing, location, quality, and other special requirements.
Choosing A Vibration Test Lab Part 1
Part 1 – Defining your project and Obtaining a Quote Vibration testing is a very specialized field, not very well understood by many. There are different types of vibration and there are an enormous number of vibration test specifications. Vibration testing equipment is very expensive to purchase forcing many companies to hire a vibration test lab to fulfill their vibration testing requirements. So what should you expect when Choosing A Vibration Test Lab?
