The MIL-STD-810G test method standard for environmental engineering considerations and laboratory tests is a publication of the US Department of Defense with contributions from the US Army, Air Force, and Navy as well as the Institute of Environmental Sciences and Technology (IEST) and the Shock and Vibration Information Analysis Center (SAVIAC) “The primary emphases are still the same – (with the exception of Method 528) tailoring a materiel item’s environmental design and test limits to the conditions that the specific materiel will experience throughout its service life, and establishing laboratory test methods that replicate the effects of environments on materiel, rather than trying to reproduce the environments themselves.
However, the “G” revision continues the up-front explanation of how to implement the environmental tailoring process throughout the materiel acquisition cycle.” (MIL-STD-810G, Part One, Forward, 1.0) First published in 1961, MIL-STD-810 has undergone a series of versions, with new test methods, clarifications and different test severities and durations. The current version MIL-STD-810G was issued on October 21, 2008, superseding MIL-STD-810F, which was last updated on May 5, 2003. MIL-STD-810 standard is designed to generate confidence in the environmental worthiness and durability of material system designs, offering test methods to accomplish the following purposes:
| ● | Define environmental stress sequences, duration and levels of equipment life cycles |
| ● | Develop analysis and test criteria tailored to the material and its environmental life cycle |
| ● | Evaluate material performance when exposed to a life cycle of environmental stresses |
| ● | Identify deficiencies, shortcomings and defects in the material design, materials, manufacturing processes, packaging techniques and maintenance methods |
| ● | Demonstrate compliance with contractual requirements |
MIL-STD-810 Testing Capabilities and Commercial Application: Although MIL-STD-810 was prepared for use by all departments and agencies of the United States Department of Defense, it is also often used to establish an excellent baseline for the testing of commercial products as well. Manufacturers of computers, cell phones, and other equipment are often tested against the standard and marketed as MIL-STD-810 compliant or ruggedized.
Testing Methods of MIL-STD-810: MIL-STD-810 details 28 testing methods covering a wide variety of environmental conditions such as rain, vibration, dust, humidity, extreme temperatures, shock and salt fog. NTS engineers are fully conversant with MIL-STD-810 standards and can help ensure your products demonstrate the necessary compliance. NTS can perform all of the tests included in MIL-STD-810 as described below.

| Products exposed to the elements will likely encounter freezing temperatures. Rigorous testing will determine if aircraft structures and controls can withstand freezing rain and ice. Such testing can be crucial for oceangoing vessels because freezing rain can impede the performance of antennas, optical devices and meteorological instruments. | Method 521.2 Icing, Freezing Rain |
