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: 

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

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,

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.  This test method is not intended for single shot gunfire from large Navy or tank guns.  Types of gunfire shock are referred to as gunfire schedules.  These shocks can include a combination

Acidic Atmosphere MIL-STD-810 Method 518 is used to evaluate protective coatings and materials resistance to corrosive atmospheres.  It is applicable for equipment that will be stored or operated in acidic atmospheres during its lifecycle.  This would include urban and industrial area environmental conditions or equipment that will be mounted near exhausts. Considerations for Acidic Atmosphere

Pyroshock MIL-STD-810 Method 517 is a test to evaluate equipment’s ability to withstand mechanical transients caused by the detonation of devices such as explosive bolts and Flexible Linear Shape Charges (FLSC).   Characteristics of Pyroshock Events Pyroshocks can produce excitation in a broad range of frequencies.  These typically range from 100 Hz to 1 MHz with

Shock MIL-STD-810 Method 516 is an environmental test that can be used to verify that equipment can withstand shocks encountered during transportation, service, and handling.  It can also be used to assess fragility levels for determination of stowage, packaging, or mounting requirements and is used to test the strength of devices such as fasteners to

Vibration, MIL-STD-810 Method 514 evaluates equipment’s ability to withstand vibration exposures expected in a product’s life cycle.  These laboratory tests simulate environmental stresses that may be experienced during manufacture / maintenance, transportation, or operational life phases.  This testing can be used for for development, qualification, or reliability purposes.  This method is not applicable for Environmental

Acceleration MIL-STD-810 Method 513 is a test method used to evaluate equipment’s ability to withstand steady state inertia loads and ensure that the test item does not create a hazard after being subjected to crash inertia loads.  This testing is intended primarily for equipment that will be installed on aircraft, helicopters, aerospace vehicles, aircraft stores,

Immersion MIL-STD-810 Method 512 is used to evaluate the ingress protection capabilities of products against water intrusion.  This is normally used for military equipment where immersion in water is a probable event in that product’s life cycle, including logistical and tactical transport.  Performance of this testing does not necessarily preclude a requirement for Blowing Rain

Explosive Atmosphere, MIL-STD-810, Method 511, is used to evaluate how equipment will function in an explosive fuel-air environment.  This method has two procedures.  Procedure I – Explosive Atmosphere evaluates the ability of equipment to operate in a fuel-air environment without causing the fuel air mixture to ignite.  Procedure II – Explosive Containment evaluates the equipment’s

MIL-STD-810 Temperature Shock testing (Method 503) is used to evaluate equipment’s ability to withstand sudden changes in temperature.  This laboratory test method is conducted in environmental test chambers and can be tailored to replicate the anticipated thermal profiles during storage, transit, and operation.  Such shock could be experienced when a jet fighter on a tarmac

MIL-STD-461 MIL-STD-461 is an EMI/EMC standard for developmental test and evaluation.  This standard is broken out into nineteen various methods.  These methods include Radiated Emissions, Conducted Emissions, Radiated Susceptibility, and Conducted Susceptibility. MIL-STD-461 testing includes radiated and conducted test methods.  These methods involve simulations of magnetic, radio frequency, Electrostatic Discharge (ESD), and Electromagnetic Pulse (EMP)

  Electrical Power considerations for MIL-STD-810 testing create a new level of detail for functional and operational tests.  The standard has placed increased emphasis in recent revisions, to changes in voltage, frequency, phase displacement, and other power deviations that are expected to be present in the normal operation of the device to be tested.
