MIL-STD-810H Drop Test: What It Means for Your Gear
MIL-STD-810H is the US military standard for environmental engineering. Method 516.8 is the drop test. Kexin cases pass 26+ drops from 1.2 m.
Direct answer: MIL-STD-810H is the US military standard for environmental testing, including drop, vibration, temperature, humidity, and immersion. The drop test (Method 516.8) specifies 26 drops from 1.22 m (4 ft) onto concrete, with each face, edge, and corner tested. Kexin performs MIL-STD-810H drop testing in-house (USD 300–500 per SKU) and offers third-party certification via TÜV / SGS for an additional USD 1,500–3,000. For most commercial cases, Premium and Trolley series pass MIL-STD-810H drop + IP67/IP68 + vibration by default.
What Is MIL-STD-810H?
MIL-STD-810H is the US Department of Defense test standard for environmental engineering considerations and laboratory testing. Published in 2019, it replaced MIL-STD-810G. The standard covers 28 environmental test methods, including drop (516.8), vibration (514.8), temperature (501.7 / 502.7), humidity (507.6), immersion (512.5), and salt fog (509.7). For protective cases, the most relevant methods are 516.8 (drop), 514.8 (vibration), 512.5 (immersion), and 509.7 (salt fog for marine applications).
MIL-STD-810 is not a pass/fail certification — it is a test methodology. The customer (typically a defense contractor, military agency, or aerospace company) specifies the test severity, duration, and pass criteria based on the use case. A protective case for a field radio may require 26 drops from 1.22 m, while a case for an airborne sensor may require vibration profiles specific to the aircraft.
MIL-STD-810H Drop Test (Method 516.8) Explained
| Test element | Specification | Notes |
|---|---|---|
| Drop height | 1.22 m (4 ft) typical | Adjustable 0.3–1.83 m per use case |
| Drop surface | Concrete (2-inch steel-reinforced) | Plywood over concrete for some test programs |
| Number of drops | 26 drops (full suite) | 1 drop per face, edge, corner, diagonal |
| Test unit configuration | Loaded with payload (typically 5–15 kg) | Match real-world use |
| Pass criteria | No structural failure, latches functional, IP rating maintained | Customer-defined |
| Test duration | 2–4 hours per case | Plus pre/post inspection (1–2 hours) |
| Test cost (per SKU) | USD 300–500 in-house, USD 1,500–3,000 third-party | — |
| Test report | Detailed per-drop log + photos | — |
The 26-drop sequence covers all faces (6), edges (12), and corners (8). Each drop uses a fresh case or the same case if the test program allows. The case is loaded with a payload matching the intended use (e.g. 10 kg for a camera case, 3 kg for a drone case). After each drop, the case is inspected for cracks, latch failure, hinge damage, and seal integrity.
Vibration Test (Method 514.8)
Vibration testing simulates transport and operational vibration. There are several categories:
- Category 4 — Truck transportation (US highways). Random vibration 0.04–0.2 g²/Hz, 60 minutes per axis.
- Category 7 — Jet aircraft. Higher amplitude, 60 min per axis.
- Category 8 — Shipboard. 30 min per axis, low frequency.
- Category 20 — Ground vehicles (tanks, trucks). High amplitude, 60 min per axis.
For most protective cases, Category 4 (truck) is the baseline. Cases used in airborne or shipboard applications require Category 7 or 8 with stricter pass criteria. Kexin tests Category 4 in-house; Categories 7/8 require third-party labs with shaker tables.
Temperature and Humidity (Methods 501.7 / 502.7 / 507.6)
| Method | Test | Typical range | Duration |
|---|---|---|---|
| 501.7 (High temp) | Storage / operational at +63 °C / +71 °C | −40 to +71 °C | 7 days (storage) or 4 hr (op) |
| 502.7 (Low temp) | Storage / operational at −40 °C / −51 °C | −51 to +25 °C | 7 days (storage) or 4 hr (op) |
| 507.6 (Humidity) | 95 % relative humidity, cycling temp | +30 to +60 °C | 10 cycles × 24 h |
| 500.6 (Low pressure) | Altitude simulation | Up to 12,000 m | 1 hour |
For most commercial cases, the high-low temperature test is mandatory; humidity is required for tropical or maritime deployment. We test all Kexin Premium and Trolley cases from −40 °C to +80 °C operational, with humidity 95 % at +60 °C for 240 hours. This exceeds the MIL-STD-810H requirement.
Immersion (Method 512.5) and Salt Fog (509.7)
Method 512.5 covers water immersion (1 m for 30 min, similar to IP67) and rain (1.7 mm/min for 30 min). Method 509.7 covers salt fog exposure (5 % NaCl, 48 or 96 hours) for marine applications. Kexin performs both tests in-house. For deeper immersion (IP68-equivalent), we extend Method 512.5 to 2 m for 1 hour (or 10 m for 1 hour for dive housings).
MIL-STD-810H vs IP vs ATA 300 vs ASTM D4169
| Standard | Focus | Geographic region | Industry |
|---|---|---|---|
| MIL-STD-810H | Environmental (drop, vibration, temp, humidity, immersion) | Global (US-DoD origin) | Defense, aerospace, outdoor electronics |
| IEC 60529 (IP) | Dust + water ingress | Global | All electronics |
| ATA 300 | Airline shipping durability (drop, vibration, stacking) | Air transport | Cases shipped by air |
| ASTM D4169 | Transport simulation (vibration, shock) | US | Commercial shipping |
| IEC 60068 | Environmental testing (similar to MIL-STD-810) | Global | Electronics |
MIL-STD-810H is the most comprehensive but also the most expensive. For B2B cases sold to commercial customers, IP + ASTM D4169 (transport) is usually sufficient. For defense and aerospace, MIL-STD-810H is mandatory. We recommend IP + MIL-STD-810H drop + vibration for Premium and Trolley — this covers 90 % of customer use cases.

FAQ
What is MIL-STD-810H?
US Department of Defense environmental test standard, published 2019, replacing MIL-STD-810G. Covers 28 test methods including drop (516.8), vibration (514.8), temperature (501.7/502.7), humidity (507.6), and immersion (512.5).
How high is the drop in MIL-STD-810H?
Default drop height is 1.22 m (4 ft). The standard allows adjustment from 0.3 m to 1.83 m depending on use case. Most Kexin cases are tested at 1.22 m; airborne sensor cases may be tested at 1.83 m.
How many drops in MIL-STD-810H?
26 drops total: 6 faces, 12 edges, 8 corners. Each face/edge/corner is tested once, either with a fresh case or sequentially with the same case (customer-specified).
Is MIL-STD-810H required for B2B cases?
Not for commercial cases. MIL-STD-810H is required for defense, aerospace, marine, and government customers. For commercial B2B (photography, drones, medical), IP + drop test at 1.22 m is usually sufficient.
What's the cost for MIL-STD-810H certification?
In-house drop + IP + vibration: USD 800–1,500 per SKU. Third-party full MIL-STD-810H (drop + vibration + temperature + humidity + immersion + salt fog): USD 3,000–6,000 per SKU, 2–4 weeks.
What's the difference between MIL-STD-810G and 810H?
810H (2019) revised test methods for vibration, temperature, and humidity to reflect newer military equipment. Drop and immersion methods are similar. Most test programs accept either 810G or 810H.
Can you drop-test in-house?
Yes. Kexin's lab has a 2 m drop tower, concrete and plywood surfaces, and payload up to 30 kg. We perform drop tests daily for Premium and Trolley production. Vibration testing requires a shaker table (third-party).
How long does MIL-STD-810H test take?
Drop test: 2–4 hours per case (plus setup/inspection). Vibration: 60 min per axis × 3 axes = 3 hours. Temperature: 7 days. Humidity: 10 days. Full program: 2–4 weeks including pre-test setup and report writing.
Is MIL-STD-810H the same as military-grade?
"Military-grade" is a marketing term. MIL-STD-810H is a specific test standard. A case "designed to MIL-STD-810H" means it was tested per the standard, but the actual pass criteria depend on the customer's specification.
Do you provide MIL-STD-810H test reports?
Yes. Each shipment can include a test summary. Full per-drop / per-test reports are USD 50–200 per case (third-party). Reports are archived 5 years and available on request.
What about MIL-STD-461 (EMC)?
MIL-STD-461 covers electromagnetic compatibility, not environmental. It's typically for electronic equipment inside the case, not the case itself. We can refer you to EMC test labs if your payload requires MIL-STD-461.
Is MIL-STD-810H accepted in EU?
Yes, globally. The EU equivalent is IEC 60068 (similar methods). Many customers accept either MIL-STD-810H or IEC 60068. We test per MIL-STD-810H by default; IEC 60068 testing is available on request.
Does MIL-STD-810H replace IP rating?
No. IP rating (IEC 60529) and MIL-STD-810H are complementary. IP covers ingress only. MIL-STD-810H covers drop, vibration, temperature, humidity. Most Kexin Premium and Trolley cases carry both: IP67/IP68 + MIL-STD-810H drop + vibration.
