This test is to be performed in environmental chambers and replicates natural exposures expected in hot-dry regions of the world. The standard defines dust as particles with a diameter less than 150 μm. Sand … Read more
Mechanical Vibrations of Shipboard Equipment, MIL-STD-810, Method 528 is performed to meet U.S. Navy requirements for environmental and internally excited vibration of equipment designed for installation aboard navy ships. These vibration tests were derived from MIL-STD-167 and was added along with lessons learned to MIL-STD-810 in Revision G. As with other testing for Naval requirements, … Read more
Rail Impact MIL-STD-810 Method 526 replicates railcar impact conditions to evaluate tie down systems and tie down procedures used in the transport of equipment. This test is not a laboratory test but is performed actual rail cars involved in the impacts during coupling. It normally involves car impact testing at speeds under 8 mph (12.9 … Read more
Freeze-Thaw MIL-STD-810 Method 524 is used to evaluate equipment’s ability to withstand transitions in temperatures through the freeze point in the midst of ambient temperatures and when transitioned from environments of varying temperatures. Effects of exposures to these environmental conditions include: binding or distortion of parts, failure of seals, adhesives, and materials, and fogging of … Read more
DHS cybersecurity assessment criteria has been released that will set the bar for businesses seeking contract awards from the agency. The U.S. Department of Homeland Security has released this information to ensure that appropriate levels of “cyber readiness” are in place by its vendors. The DHS plan, released by Chief Information Security Officer Kenneth Bible, is … Read more
Vibro-Acoustic/Temperature MIL-STD-810 Method 523.4 testing is performed to evaluate the effects of acoustic noise, vibration, and temperature on aircraft externally carried stores during flight. Aircraft stores refer to devices that are mounted on aircraft suspension and release equipment such as missiles, rockets, or bombs. This MIL-STD-810 testing method can be used to: Reveal and correct … Read more
Ballistic Shock MIL-STD-810 Method 522 evaluates equipment designed for armored combat vehicles’ ability to withstand the shock associated with non-perforating large caliber munition impact or blast. This testing can be used to provide a degree of confidence in the the equipment’s ability to function after such a shock, or be used to evaluate shock mitigation … Read more
Icing/Freezing Rain MIL-STD-810 Method 521 testing is used to verify that equipment can operate when exposed to ice accumulations from rain, drizzle, or sea spray. Freezing rain tests can also be used to evaluate de-icing equipment and techniques. Types of Ice Used in Testing Two types of icing is likely to occur in natural exposures: … Read more
Monitoring of operational testing and the recording of all critical performance parameters has become a requirement in MIL-STD-810H. Operational testing has been a part of MIL-STD-810 since Revision C in 1975. It refers to testing the item in a manner that represents service use as documented in the mission profile. Changes in Monitoring Requirements Successive revisions … Read more
Combined Environments MIL-STD-810 Method 520 is used to evaluate the synergistic effects of multiple environmental stressors on equipment intended airborne applications. The use of synergetic effects can uncover failures effecting the safety, performance, or integrity of equipment under test that individual stresses would not reveal. Environmental factors that are applicable to this method are vibration, … Read more
Gunfire Shock MIL-STD-810 Method 519 testing is performed to ensure that equipment can operate and structurally withstand short duration, high-rate shocks from gunfire.
