When sourcing mobile devices for industrial work, you will frequently see the term MIL-STD-810G. While MIL-STD-810G is widely cited on product data sheets, the most current version of the standard is MIL-STD-810H. The principles discussed here apply to all revisions. This U.S. Military Standard indicates a high level of durability, assuring users that a device can withstand drops, vibrations, and extreme temperatures. However, this often leads to a critical misunderstanding: many assume this ruggedness certification is enough for explosive or hazardous atmospheres. This is a dangerous mistake. While a device certified to this standard is tough, understanding what is MIL-STD-810G certification shows that it is not designed, tested, or certified to prevent ignition in explosive atmospheres. For genuine safety in environments with flammable gases, dust, or fibers, specific certifications like ATEX, IECEx, or NEC Class/Division are non-negotiable and can never be replaced by a ruggedness rating.
Go Beyond Rugged: Understand True Hazardous Area Safety
MIL-STD-810G proves a device is tough, but intrinsic safety proves it won’t cause an explosion. Learn the core principles of designing equipment for hazardous locations.
What MIL-STD-810G Actually Tests
MIL-STD-810G is a standard from the U.S. Department of Defense for testing equipment against the environmental stressors it might face during its service life. It isn’t a single test or a fixed certification, but a series of 29 laboratory test methods that simulate conditions from desert heat to arctic cold and transportation shock. A manufacturer selects the tests relevant to their product’s intended use. For example, a tablet for field use would likely undergo drop, vibration, and temperature tests, but not a ballistic shock test designed for naval equipment. Compliance with MIL-STD-810G means the device passed specific methods within the standard, not all of them. This flexibility is important, but it also means buyers must check which specific tests were performed to understand a device’s true capabilities.
Key Environmental Tests Under MIL-STD-810G
While the standard is extensive, several test methods are commonly applied to rugged commercial devices like tablets, smartphones, and laptops. These tests ensure the device can survive the physical demands of industrial and field work, which is valuable, but separate from explosive atmosphere safety.
- Method 516.6 – Shock: This is arguably the most well-known test, often referred to as the ‘drop test.’ It evaluates how well a device withstands sudden impacts. It typically involves dropping the device from a height of about 4 feet onto plywood over concrete multiple times on different faces, edges, and corners.
- Method 514.6 – Vibration: This procedure simulates the vibrations a device might experience during its lifetime, such as being mounted in a vehicle driving over rough terrain. It tests for component fatigue and mechanical failure from sustained shaking.
- Method 501.5 & 502.5 – Temperature (High & Low): These tests assess the device’s ability to operate and survive in extreme temperatures. High-temperature tests check for performance degradation in hot climates, while low-temperature tests ensure it can function in freezing conditions.
- Method 507.5 – Humidity: This test evaluates how the equipment performs in warm, humid environments. It checks for issues like condensation, corrosion, and material degradation caused by prolonged exposure to moisture in the air.
The Critical Distinction: MIL-STD-810G vs. Hazardous Area Certifications
Here is the most important distinction: MIL-STD-810G is a standard for environmental and mechanical ruggedness, not for electrical safety in explosive atmospheres. A device can be tough enough to survive a 10-foot drop but still produce a tiny internal spark capable of igniting a flammable gas cloud. This is why hazardous area certifications are absolutely required.
- Purpose of Certification: MIL-STD-810G confirms durability and reliability under physical stress. In contrast, standards like ATEX, IECEx, and NEC (Class/Division) are designed solely to prevent explosions by controlling ignition sources (sparks, heat).
- Testing Focus: MIL-STD-810G tests for external threats like impacts, water ingress (via IP ratings, which are separate but often paired), and temperature extremes. Hazardous area standards test the internal electrical design, ensuring energy levels are too low to ignite a specified atmosphere (Intrinsic Safety) or that any internal explosion is contained (Explosion Proof).
- Environment of Use: A MIL-STD-810G device is suited for physically demanding environments like construction sites, manufacturing floors, or logistics. An ATEX/IECEx certified device is legally required for potentially explosive environments like oil refineries, chemical plants, grain elevators, and paint booths.
- Consequence of Failure: If a MIL-STD-810G device fails its drop test, the screen might crack. If a non-certified device is used in a hazardous area and creates a spark, the consequence could be a catastrophic explosion, leading to severe injury, loss of life, and facility destruction.

Frequently Asked Questions
Is MIL-STD-810G the same as intrinsically safe?
No, they are completely different. MIL-STD-810G is a military standard for environmental ruggedness (e.g., drops, vibration). Intrinsic safety is an electrical design standard (e.g., ATEX, IECEx) that ensures a device cannot produce a spark or heat capable of igniting an explosive atmosphere.
What does the ‘G’ in MIL-STD-810G stand for?
The ‘G’ indicates the revision letter of the standard. MIL-STD-810 has been updated several times since its inception in 1962. Revision G was released in 2008, and the current revision is H, released in 2019. The core principles remain similar across recent revisions.
Are MIL-STD-810G devices always waterproof?
Not necessarily. Waterproofing is tested under a separate system known as the Ingress Protection (IP) rating (e.g., IP67, IP68). While most rugged devices that are MIL-STD-810G compliant also have a high IP rating, the military standard itself primarily focuses on other stressors like shock and temperature.
Can a device be both MIL-STD-810G and ATEX certified?
Yes, and this is common for high-quality hazardous area equipment. The best devices for harsh, explosive environments carry both types of ratings. This combination ensures the device is both physically durable for the job and electrically safe for the location.
Why is MIL-STD-810G important for industrial devices?
Even outside of classified hazardous areas, industrial environments are tough on electronics. MIL-STD-810G provides assurance that a device has been tested to withstand the drops, shocks, and vibrations common on a factory floor or in the field, leading to a longer lifespan and lower total cost of ownership.
