Product Announcement from E-Labs, Inc.
Dynamics testing is common in commercial, industrial, and military applications. At E-Labs, Inc. our dynamics testing capabilities include the following:
- Acceleration Testing
- Acoustic Noise Testing
- Classical Shock Testing
- Combined Environments Vibration Testing
These tests can be performed individually or in combination with temperature cycling and hydraulic flow tests.
Acceleration testing is used to detect structural and mechanical strength limits in objects that experience constant acceleration. E-Labs can perform centrifuge tests to meet acceleration requirements of MIL-STD-810 method 513.5, MIL-STD-202 method 212A, MIL-STD-750 method 2006 and other specifications. Our centrifuge has multiple slip rings and RF connectors to meet all your needs. E-Labs has adjustable fixtures that allow the test item to be tilted and rotated in order to match combined load vector test requirements.
Acoustic Noise Testing
Acoustic noise occurs when sound pressure waves travel through the air and are measured in psi or decibels. We have the instrumentation to measure and analyze the sound waves produced to determine compliance to your specification.
Acoustic Noise testing is performed to Mil-std 740 and other standards, E-Labs has performed many acoustic tests for the US Navy on submarine components, let us handle your requirements.
Classical Shock Testing
Classical Shock Testing is accomplished using many facilities here at E-Labs. The typical shock testing event can be performed on our Ling Electronics 335 or UD T-508 vibration testing systems.
For tests that required higher levels or longer duration, E-Labs has additional mechanical shock testing machines. Using these shock testing facilities we can achieve customs shock levels to meet our customers needs.
At our lab, the test item size is never an issue from small to large we can accommodate most any size unit. We can simulate such profiles as the road shock to the shock of a torpedo hitting a submarine or the side of a ship.
Combined Environments Vibration Testing
We have the flexibility to turn any of our 3 vibration systems into combined environments, combining temperature/humidity chambers with electro-dynamic vibration shakers. The chambers can perform rapid rates of temperature change and the vibration facilities can produce up to 20,000 force-pounds, with frequencies up to 2000 Hz. The durability of the product is tested for each individual stress and also for the combined interaction of all stresses. This will allow for quick exposure of any design or manufacturing weaknesses.
Lightweight Hammer Shock Testing
E-Labs has light weight hammer shock testing facilities that test the ability of shipboard installations to withstand shock loadings. These shock testing facilities are totally capable of performing Mil-S-901 test requirements.
During lightweight hammer shock testing, an article is fixed to an anvil plate which is struck by a pendulum hammer at 1, 3, and 5 foot heights. The anvil plate is struck at three orientations top, back, and side blows. Testing sequence will depend on the operating condition that is to be represented.
Shock Testing Services
Our shock testing engineers will condition, plot and help you analyze up to 128 channels of real time data - Shock Response Spectrum (SRS), Fast Fourier Transform (FFT) or modal analysis.
They will review the cause and effect of shock pulses and help in estimating damage potential based on the analytical data results. They will also be able to offer solutions for those scenarios that do not meet specifications.
Vibration testing can help validate your design to see if it will survive its intended environment. It simulates a variety of transportation scenarios, operating environments, and the effect of external vibration within a storage environment. Our vibration testing facility is comprised of 3 electrodynamic shakers capable of providing over 20,000 force pounds performing multiple types of vibration such as sine, random, sine on random, random on random and vibration analysis. They are capable of product vibration in a single as well as multiple axis configuration in order to meet your type of testing.
Test applications include transportation load simulations, fatigue due to vibration, reliability testing, squeak & rattle testing, fragility, production stress screening, and package testing, among others.

Lightning Direct Effects*
MIL-STD-167-1 details the mechanical vibration testing requirements for shipboard equipment. Equipment designed and tested in accordance with MIL-STD-167-1 generally passes the shock requirements of MIL-S-901 with little difficulty.
This deals with Environmental Engineering Considerations and Laboratory Tests, which include shock testing and vibration testing.
MIL-STD-810 talks about a vast range of environmental testing procedures and standards that we are fully equipped to offer you such as the following:
500.4 Low Pressure 501.4 High Temperature 502.4 Low Temperature 504 Contamination by Fluids 505.4 Solar Radiation 506.4 Rain 507.4 Humidity 508.4 Fungus 509.4 Salt Fog 510.4 Sand and Dust 511.4 Explosive Atmosphere 512.4 Immersion 513.4 Acceleration 514.4 Vibration 515.4 Acoustic Noise 516.4 Shock 517.4 Pyroshock 518.4 Acidic Atmosphere 519.4 Gunfire Vibration 520.4 Temperature, Humidity, Vibration and Altitude 521.4 Icing/Freezing Rain 522.4 Ballistic Shock
MIL-S-901 details the high-impact shock testing requirements for shipboard machinery, equipment, structures and systems.
The purpose of these MIL-S-901 requirements is to verify the ability of shipboard installations to withstand shock loadings, such as the effects of nuclear or conventional weapons.
