GVIRL Defense: Capabilities

GVIRL Defense is a leading provider of testing, evaluation and engineering services for the defense industry, and we have the technical expertise, accreditations and physical infrastructure needed to meet the needs of our extensive customer base in both the public and private sectors.

GVIRL Defense laboratories maintain multiple contract levels with the government, strictly adhere to National Industrial Security Operating Manual (NISPOM) regulations, and are accredited to a wide range of regulatory standards, including:

• MIL-STD-810— the “Department of Defense Test Method Standard for Environmental Engineering Considerations and Laboratory Tests” — covers most of the environmental factors encountered during the use of military equipment in all stages of its service life. MIL-STD-810 testing involves replicating these conditions in a controlled laboratory environment through the use of temperature, humidity, shock, vibration, acceleration and other simulation equipment.
• MIL-STD-461— the “Department of Defense Requirements for the Control of Electromagnetic Interference Characteristics of Subsystems and Equipment” — covers the EMC and EMI requirements for all electrical and electronic equipment used in defense applications. GVIRL has a network of facilities that can perform MIL-STD-461 testing in-house using highly controlled, anechoic chambers. We can also perform MIL-STD-461 testing in situ, when it is required for components that are too large or too expensive to transport to one of our locations.
• MIL-STD-2105— the “Department of Defense Test Method Standard Hazard Assessment Tests For Non-Nuclear Munitions” — involves fragment impact testing, external fire, fast and slow cook-off testing, and bullet-impact testing using small- and medium-caliber ammunition. The National Ordinance and Ballistics Center at GVIRL Camden (Arkansas) is equipped with multiple firing ranges and sophisticated monitoring equipment for performing testing to all MIL-STD-2105 requirements.
• MIL-DTL-901E— the “Department of Defense Requirements for Shock Tests, High Impact, Shipboard Machinery, Equipment, and Systems” — is the military standard governing shock-resistance requirements for shipboard equipment. Previously called MIL-S-901D, the certification is required for principle devices, subsidiary components and subassembly components, including both those that are essential for safety and combat, and those that could become hazardous to the crew if exposed to shock. Shock testing to MIL-S-910 standards can be performed at GVIRL labs across the country. Our Rustburg, VA location is specially equipped with a 36-acre facility with an 1,800 x 250 x 130-ft. quarry for heavyweight applications.
• MIL-STD-167— “Department of Defense Test Method Standard: Mechanical Vibrations of Shipboard Equipment” — is similar to MIL-STD-901D but covers specifically the effects of environmentally and internally excited vibrations on shipboard equipment. Replicating these factors in a controlled laboratory environment requires powerful shakers and precise instrumentation. GVIRL maintains some of the best-equipped facilities in the country for MIL-STD-167 vibration testing. Contact our head office to discuss your requirements and find a testing lab near you.

GVIRL has been a partner to defense and naval contractors for more than 50 years. In addition to the above, we can provide testing to other defense standards, including MIL-STD-120 (gage inspection), MIL-STD-248 (welding and brazing procedures), MIL-STD-516 (airworthiness) and MIL-STD-767 (control of hardware cleanliness). For more information or to request a quote, contact an GVIRL location near you.
