National Technical Systems Announces Industry’s Highest Level Single System Vibration and Shock Capability

CALABASAS, CA – November 28, 2005 – National Technical Systems, Inc. (NASDAQ:NTSC) (NTS) announced today installation of the new Unholtz-Dickie T-2000 vibration system. Installed at NTS Camden, NTS becomes the only Defense/Commercial testing laboratory in the with a T-2000 system, which is one of the most powerful in the industry. The system can produce very high-level, high-displacement vibration and shock profiles as it is rated at 24,000 force pounds random (peak) and 25,000 force pounds sine (peak). NTS’ laboratories conduct vibration and shock testing, and provide regulation compliance certification on products ranging from missiles and radar systems to telecommunications equipment and automotive subsystems. Nationwide, NTS has approximately one hundred operational electrodynamic shaker systems.

The system, built by Unholtz-Dickie a leading manufacturer of electrodynamics systems, produces very high energy levels for inducing vibration and shock in large test specimens. At NTS Camden, the testing is conducted in accordance with various military and commercial test specifications to determine how much shock and vibration the specimen can endure and still operate. The system features a full 3-inch (76mm) stroke and is capable of up to 200g of sine acceleration and up to 600g of shock acceleration.  Internal pneumatic load support provides automatic test sample (load) centering for full stroke capability with payloads up to 1,900 lbs.

The NTS National Ordnance and Environmental Test Center (NTS Camden) is unique as one of the few independent test facilities equipped to conduct the wide array of complex development, qualification and acceptance tests on weapon systems, ordnance, rocket motors, hazardous materials and commercial products required by government and commercial standards. In support of these test programs, NTS provides experienced test personnel, specialized test equipment and infrastructure, engineering support, diagnostic instrumentation, data acquisition, and analysis. The multidiscipline test facility also features a 3,000-meter Large Caliber Ballistics Range; a rocket range; a large function and Arena Test area for weapons, munitions and warheads; Shock and Drop tower facilities; large Dynamics and Climatic test facilities; and numerous large concrete storage magazines for ordnance.

“Whether it’s a commercial or military product, this system allows customers to induce the toughest imaginable environments on their products to assure product performance, safety and reliability,” states Dave Mann, Division Manager of NTS Camden.
