Military / Defense Testing - Clark Testing

Military / Defense Industry Testing



Crucial to the nation’s defense, our military demands the most robust and reliable equipment on the market. As an independent test laboratory, we offer a wide variety of capabilities to validate equipment integrity before it is used by our service members. Just as our Soldiers, Sailors, Airmen, and Marines are expected to operate ‘on-time, and on-target,’ we hold ourselves to the same stringent standards for quality and technical excellence.

Clark Testing has a long history of supporting equipment qualification and component validation for the defense industry. Test programs are conducted under extreme conditions with our unique capabilities on heavy equipment and large components. Typical common tests include: MIL-STD-810 for environmental engineering considerations, Def-Stan (the UK version of MIL-STD), MIL-STD-461 for electromagnetic compatibility, MIL-STD-901 for medium weight shock testing and RTCA/DO-160 for environmental conditions and test procedures for airborne equipment.

MIL-STD-810G Environmental Testing


Clark Testing maintains an array of shakers and chambers necessary for equipment qualification in accordance with Mil-Std-810G. We understand that customers often impose difficult requirements for qualifying equipment in the defense industry.

Whether it be temperature / humidity cycling, shock and vibration, or salt fog, we pride ourselves on being able to ‘improvise, adapt, and overcome’ – helping you find a unique and cost-effective solution to accommodate your program’s needs.

We also offer HALT / HAFT capabilities for programs that require extreme, highly-accelerated aging.


MIL-STD-901D - Medium Weight Shock


High impact shock testing is used regularly to qualify critical shipboard equipment for combat-essential operations. Clark regularly performs medium weight shock testing on equipment for naval shipboard application. How does your equipment hold up against a 115g shock wave?


MIL-STD-461 EMC/EMI


Clark Testing has a fully accredited EMC laboratory providing compliance testing for equipment manufacturers throughout the United States. Our EMC lab has anechoic and semi-anechoic chambers, copper shielded rooms and ground planes. Clark Testing's EMC lab is FCC compliant and 17025 accredited by NVLAB.


Fuels & Lubrication


Clark’s Lubrication Laboratory provides R&D, qualification, and reliability support to industries such as defense and aerospace suppliers, additives makers, lubricant manufacturers, fuel suppliers, steel manufacturers and more using ASTM, ISO, & FTM standards as our guides to provide you with quality testing and superior results. We offer assessment of new and in-service oils, greases, hydraulic fluids, and fuels.

Clark’s in-service lubrication lab works with clients to reduce failures by scheduling maintenance and downtime to avoid costly unexpected system break downs. We provide expert analysis, including spectrometry( Spec-oil and ICP), viscosity( Cannon and Anton Parr), Karl Fisher water (Coulometric and Volumetric), acid number, base number, particle counting( mineral and water based fluids), and analytical ferrography.

Clark’s lubrication lab offers specialized testing to various specifications to assist clients in meeting requirements of lubrication and fuel certifications. Specification include, ASTM D975-13 Standard Specification for Diesel Fuel Oils, ASTM D1655-12a Standard Specification for Aviation Turbine Fuels, the Morgan standard, including Dynamic Demulsibility Endurance testing, and MIL-G-46886B, MIL-G-25537C, MIL-PRF-2105E for military applications to name a few. In addition we offer wear testing including FZG 12 &14 stages, Hydraulic pump testing (mineral and water based lubricant testing), 4-Ball Wear and 4-Ball EP for greases and oils. We are experts in specialized grease analysis using methods such as Lincoln Vent Meter, LT-37 "U.S. Steel Method Mobility of Grease", Roll Stability, and LT-46 “Bethlehem Steel Combo Test Parts A & B".
