Meeting these requirements separately would alone be a challenge for any lab.  Meeting these requirements concurrently requires specialized equipment and test setup.  Good insulation is an obvious concern for this test.  The lab must ensure that heat isn’t transferred to the armature of the shaker or else costly damage can occur to the shaker system.  Extreme temperature accelerometers are also necessary if a lab wants to obtain accurate acceleration data.  DES was able to perform this test with successful results and overcome the challenges associated by utilizing their combined temperature and vibration chamber, Figure 1.
