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,

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

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

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

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

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:
