MIL-STD-810G vs MIL-STD-810H: What Changed in the 2019 Revision.

Quick Answer: MIL-STD-810H (2019) supersedes MIL-STD-810G (2008, Change 1: 2014) with refined tailoring guidance, updated test methods, and one new method (528 — Mechanical Vibrations of Shipboard Equipment). 810G remains valid for legacy programs, but new defense contracts increasingly specify 810H.

Side-by-Side Comparison

• Year published: MIL-STD-810G — 2008 (Change 1: 2014); MIL-STD-810H — 2019
• Total test methods: MIL-STD-810G — 28; MIL-STD-810H — 29
• New methods added: MIL-STD-810G — —; MIL-STD-810H — Method 528 (Mechanical Vibrations of Shipboard Equipment)
• Tailoring approach: MIL-STD-810G — Tailoring required; MIL-STD-810H — Tailoring required, with expanded design-cycle integration guidance
• Method 506 (Rain): MIL-STD-810G — Procedures I, II, III; MIL-STD-810H — Refined procedures, updated rate calculations
• Method 514 (Vibration): MIL-STD-810G — Standard; MIL-STD-810H — Updated PSD profiles for transportation
• Method 521 (Icing/Freezing Rain): MIL-STD-810G — Yes; MIL-STD-810H — Refined acceptance criteria
• Adoption status: MIL-STD-810G — Legacy programs, grandfathered contracts; MIL-STD-810H — New programs, current DoD preference

When to Choose MIL-STD-810G

810G applies when the program contract, statement of work, or qualification baseline explicitly references the G revision. Many active defense programs (F-35 subsystems, legacy ground vehicle platforms, established avionics) were qualified under 810G and continue to use it for sustainment, requalification, and incremental upgrades. Switching mid-program creates re-test burden that contracting officers typically avoid.

When to Choose MIL-STD-810H

810H is the right baseline for new defense product development, new supplier qualification, and any program with a delivery horizon past 2024. The expanded tailoring guidance in 810H integrates environmental testing earlier in the design cycle, reducing late-stage compliance failures. For shipboard equipment, Method 528 is only available in 810H — there is no 810G equivalent.

Common Misconceptions

It is incorrect to assume 810H invalidates 810G certifications. Equipment qualified to 810G remains compliant under contracts that referenced 810G. It is also incorrect to assume 810H is universally "stricter" — many test parameters are unchanged, and the differences are primarily in tailoring guidance, procedural clarity, and a small number of method updates.

ULMEKA Recommendation

Our MIL-STD-810 test chambers (Rain, Salt Fog, Dust, Acceleration, Temperature-Humidity) are configured to support both G and H revision procedures with documented method-by-method traceability. For new defense suppliers approaching 810H qualification for the first time, our Test Engineering Consultancy team can help map your product against the relevant methods before chamber time begins.
