Durability testing is performed in order to stress a mechanical or electro-mechanical device in a time compressed simulation of it's final use environment. Typically the client supplies us a test plan which defines the environmental and mechanical or electrical stress conditions which are applied to the device. The environmental, mechanical and/or electrical stresses are applied to the device in a controlled repetitive manner to accumulate the necessary use cycles.
Many durability tests require specialized test fixtures designed to load the device in the manner described in the test plan.
Some materials become brittle at low temperatures and become more susceptible to cracking under mechanical impacts.
Mechanical stresses are introduced by applying quasi-static or dynamic forces to the device and through vibration exposure.
Electrical stresses are applied through resistive, inductive or capacitive loading and by varying the electrical potential.
