Note: Trenton Systems is not a compliance testing facility. We manufacture rugged servers & workstations that conkhung lớn military và industrial standards, such as MIL-STD-810 and DO-160, và we can ensure that our systems comply with these standards using our in-house testing equipment, or by sending our systems to a third-các buổi party compliance testing laboratory for validation, but our facility does not offer compliance testing services for products manufactured outside of Trenton Systems. For a danh sách of laboratories that can assist you with your testing needs, please read this blog post, which lists the best compliance testing laboratories in the world.

Learn all about the different MIL-STD-810 thử nghiệm methods in our ongoing MIL-STD-810H series. Read the first installment here. Chechồng out our MIL-STD-810 servers blog post to learn more about rugged computers & how they"re enhancing military defense. You can also read our comprehensive MIL-STD-810 overview.


The United States Department of Defense officially released MIL-STD-810H, the successor lớn MIL-STD-810G, in January of 2019.

With this revision comes numerous changes, both minor & major, to lớn MIL-STD-810’s laboratory demo methods.

In this blog post, we’ll Đánh Giá MIL-STD, MIL-STD-810G, & include an outline of the changes made in MIL-STD-810H. Stiông chồng around for a comprehensive overview.

What is MIL-STD?

MIL-STD is just an acronym for military standard.

In the United States, military standards, or defense standards, are enforced by the U.S. Department of Defense and maintained by the Air Force, Army, & Navy.

If a product is MIL-STD-certified or MIL-STD-compliant, that product is compliant with certain requirements và standardization objectives mix forth by the DoD.

According lớn the DoD, the purpose of military standards is lớn ensure the interoperability và commonality of products và equipment used in military applications.

“Standardization documents are developed & used for products, materials, and processes that have sầu multiple applications khổng lồ promote commonality và interoperability aý muốn the Military Departments và the Defense Agencies và between the United States & its allies, & lớn limit the variety of items in the military supply system,” the Department’s website states.

In a nutshell, by establishing equipment consistency và compatibility, these standards safeguard against equipment incongruity, inefficiency, ineffectiveness, và worst-case scenario, failure in the field.

MIL-STD-certified products are usually designed lớn survive sầu in extreme environmental conditions. This process is known as usually referred to lớn as environmental găng tay testing, compliance testing, or ruggedization, which means to lớn “strengthen for better resistance to wear, găng tay, and abuse,” according to lớn Merriam-Webster.

Military standards are a vital part of sản phẩm development for companies that sell equipment to lớn the military, which needs to lớn ensure that such equipment can sustain and continue operating properly in the face of extreme environments that could cause damage or malfunction.

MIL-STD is also sometimes referred khổng lồ as a MIL-SPEC, which stands for military specification. When shopping for or reading about MIL-STD-certified computers, you’ll often see them referred lớn as a MIL-SPEC server, a MIL-SPEC workstation, or just "MIL-SPEC computer." This just means that they meet some sort of military specification, such as MIL-STD-810.

What is MIL-STD-810?

MIL-STD-810, officially entitled "Environmental Engineering Considerations và Laboratory Tests," is a military standard that outlines the testing and design requirements of equipment used by the military lớn verify the equipment"s ability lớn sustain environmental găng incidents throughout its life cycle.

Some of the kiểm tra methods & procedures that a MIL-STD-810-certified hàng hóa may undergo include but are not limited lớn mechanical shochồng, vibration, temperature, low pressure (altitude), humidity, fungus, salternative text fog, and explosive atmosphere.

Testing and certifying equipment to lớn these and other harsh conditions lets military contractors know that the products they’re purchasing are durable, reliable, sustainable, and fit for a solution that"s being sold lớn the DoD for use in extreme environments.

What tests are included in MIL-STD-810G testing?

MIL-STD-810G is the precursory revision khổng lồ MIL-STD-810H, the lathử nghiệm revision published in 2019.

The DoD published MIL-STD-810G in 2008 & revised it in năm trước.

MIL-STD-810G is divided into lớn three parts:

Environmental Engineering Program GuidelinesLaboratory Test MethodsWorld Climatic Regions – Guidance

Test methods are what interest most contractors. A MIL-STD-810G-certified hệ thống may undergo a combination of assessments for resistance khổng lồ gunfire shock, pyroshoông xã, acoustic noise, immersion, contamination by fluids - any of the methods listed in document. Each of these methods include one or more testing procedures that allow chạy thử engineers tailor an assessment to lớn a product"s over environment.

For example, MIL-STD-810 immersion testing measures equipment"s performance & durability while partially or totally immersed in water; therefore, the Navy might be interested in ensuring that a sản phẩm they"re purchasing is certified to lớn this standard.

What changes are included in MIL-STD-810H?

MIL-STD-810H, the lakiểm tra revision of MIL-STD-810, includes numerous changes from its predecessor, MIL-STD-810G.

As you"ll see, the standard underwent a multitude of changes and updates for its “H” iteration.

When reviewing the 1,089-page MIL-STD-810H, here’s what you can bởi vì to lớn make your search for specific changes easier:

Cliông xã on the hyperlinks under "Part Two – Laboratory Test Methods," which begins on Page 7. These link will take you directly khổng lồ your test method of interest.chú ý the thin, blaông xã lines in the left-hvà margins of the document. These signify changes from the previous revision, MIL-STD-810G.

It"s important to note that mechanical shoông xã, one of the most widely used testing methods, underwent extensive changes for MIL-STD-810H & therefore does not include line revision indicators.
