Shock Testing Capabilities at Keystone Compliance
Keystone Compliance offers shock testing on our electrodynamic shakers as well as through the use of our pneumatic shock machine. Additionally, Keystone Compliance possesses the necessary equipment to produce and analyze Shock Response Spectrum (SRS) shock events. The latest revisions of many federal and military specifications are requiring, or offering, shock response spectrum as an alternative to typical classical shock testing.
Our equipment is capable of delivering shock pulses exceeding 3,000 g’s. Shock testing on our electrodynamic shakers can be performed during vibration testing, prior to axis rotation, greatly reducing test time. Our staff has over twenty years of experience in the performance of SRS shock. Elaborate SRS shock profiles are a specialty at Keystone Compliance.

Shock Testing Overview
Shock tests, per MIL-STD 810 Method 516.5, are performed to assure that material can withstand the relatively infrequent non-repetitive shocks or transient vibrations encountered in handling, transportation and service environments. Shock tests are also used to measure an item’s fragility, so that packaging may be designed to protect it, if necessary, and to test the strength of devices that attach equipment to platforms that can crash.
Mechanical shocks will excite an equipment item to respond at both forced and natural frequencies. This response, among other things, can cause:
- Failures due to increased or decreased friction, or interference between parts.
- Changes in dielectric strength, loss of insulation resistance, vibrations in magnetic and electrostatic field strength.
- Permanent deformation due to overstress.
- More rapid fatiguing of materials (low cycle fatigue)
