MIL-STD-810H

What is MIL-STD-810?

MIL-STD-810 is a U.S. Department of Defense standard of environmental engineering considerations and laboratory test methods. The current revision, MIL-STD-810H (2019), covers shock, vibration, humidity, salt fog, sand and dust, low pressure and temperatures from −80 °F to +160 °F.

It is not a “military approved” certification. Each method tests one environmental factor and each procedure sets specific conditions, so products are “tested to” named methods. Always ask which methods, which procedures and what conditions.

MethodEnvironmentTests forWhy it matters for a SunCase™
500.6Low pressure (altitude)High-altitude operationAir-mobile and mountain ops; transport in pressurized aircraft

NUE status.

MIL-STD-810 compliance is on NUE’s published roadmap. SunCase is engineered to the standard’s environmental targets, and the Arctic configuration is tested to −40 °F with heating elements and insulation around the LiFePO₄ cells. Formal test documentation is in process, and the DIU / U.S. Army energy nodes arriving July 2027 are MIL-STD-810 certified.

Five questions to ask any vendor.

  • Which methods and procedures were run?
  • What conditions (temperature, duration, profile)?
  • Was the testing tailored to my mission life cycle?
  • Which lab, and is there a dated report with serial numbers?
  • Was the unit operating during the test, or only stored?

Revisions

MIL-STD-810G vs. 810H.

810H (January 2019) is current. It updated test methods, clarified tailoring to real operational use, and refined humidity and temperature-shock procedures. 810G (2008) is still referenced in some legacy procurements.

For portable power, the methods that matter most are temperature (501/502/503), sand and dust (510), vibration (514) and shock (516): the conditions a battery generator actually sees in a truck bed, a sling-load or an arctic OP. Deep dive: MIL-SPEC portable power explained · extreme environments.

Trade compliance

TAA, Berry and Buy American: what’s the difference?

The Trade Agreements Act of 1979 limits U.S. federal purchases to U.S.-made or “designated country” products (about 130 nations with reciprocal agreements). It applies to GSA Schedule buys and most federal contracts above the simplified acquisition threshold.

TAA is not “Made in USA.” Products from the UK, Germany, Japan or Canada can qualify; products from China, Russia and India generally do not.

RuleWhat it requiresWho it applies toRelevance to portable power
TAAU.S.-made or designated-country origin (~130 countries)GSA Schedule and most federal contracts above the SATThe relevant standard for batteries, electronics and solar
Berry AmendmentDomestic only; no designated-country fallback (10 U.S.C. § 4862)DoD, for food, clothing, fabrics, fibers and hand/measuring toolsGenerally not applicable to batteries and electronics
Buy American (BAA)Domestic end products and components (FAR 52.225)Federal purchases, often below TAA thresholdsDIU / U.S. Army SunCase nodes are BAA compliant (July 2027)
NDAA §154 (FY2024)No DoD funds for batteries from six named Chinese producersDoD procurement, from Oct 1, 2027Ask every vendor for cell-level sourcing

NUE status: TAA.

NUESolar tactical panels, including the NUESolar 150 Tactical Ultralight Folding Solar Panel, are TAA compliant and eligible for federal procurement. NUE is moving the full line toward a domestic supply chain and U.S. manufacturing as part of its Series A plan.

Is Berry different from TAA?

Yes, and it is stricter: no designated-country fallback, and it applies only to DoD and a defined item list. Most batteries and electronics are TAA-covered, not Berry-covered, so TAA is the standard that matters for portable power. Contractors: see supplier vetting and battery sourcing.

Ingress protection

What IP rating does portable power need?

An IP (Ingress Protection) rating is a two-digit IEC 60529 code: the first digit for solids (0–6), the second for liquids (0–9). IP65 is the practical tactical minimum: dust-tight and protected against water jets. IP67 adds immersion to 1 m for 30 minutes.

IP54
Limited dust, splashing waterGarrison and barracks only
IP65
Dust-tight, water jetsField deployment, motor pool, vehicle-mounted
IP66
Dust-tight, powerful water jetsNaval, littoral, helicopter-wash exposure
IP67
Dust-tight, 1 m immersion for 30 minRiverine, amphibious assault, monsoon ops
IP68
Dust-tight, continuous immersionSpecialized maritime equipment

The SunCase™ operates with its case closed, ports covered, in dust, rain and field conditions consistent with these ratings, and runs upright or lying flat in a truck bed or bunker.

Battery safety

Which chemistry meets military safety standards?

LiFePO₄ (LFP) is the military-standard choice for battery generators: greater thermal stability, a very low thermal-runaway risk under combat load and impact, 3,000+ cycles versus 500–1,000 for NMC, and safe indoor and underground use. Every NUE SunCase uses prismatic LiFePO₄ cells.

Logistics

How are LiFePO₄ batteries moved by military air?

Lithium transport is governed by the IATA Dangerous Goods Regulations, 49 CFR for U.S. ground shipment, and DoD airlift rules. Watt-hour capacity, state of charge and packaging all affect approval, and every lithium battery must pass UN38.3 testing.

Can a SunCase go on military aircraft? Yes, subject to standard lithium transport rules and packaging. NUE is working with the Department of War on streamlined approvals for larger SunCase systems, a near-term roadmap item.

What “Made in America” means right now.

The industry depends heavily on Asian-made cells, BMS components and inverter electronics. A unit can be U.S.-assembled with imported parts: TAA compliant, but not Berry compliant. Drawing on DoD supply-chain security and lessons from Ukraine’s logistics, NUE has publicly committed to a fully domestic supply chain with U.S.-built components, competitive pricing and on-demand availability.

Frequently asked questions

Compliance questions, answered.

Is MIL-STD-810 a certification?
No. It is a test standard. Vendors test against specific methods and procedures and document the results, so ask which methods and conditions were used.
What’s the difference between MIL-STD-810G and 810H?
810H (January 2019) is current. It updated test methods, clarified tailoring to operational use, and refined humidity and temperature-shock procedures. 810G is still referenced in legacy procurement.
Does TAA mean Made in USA?
No. TAA allows U.S. or designated-country manufacture (about 130 countries). UK, German or Japanese products can qualify; Chinese products do not.
Are NUE products on the GSA Schedule?
NUE is expanding federal channels. NUESolar tactical panels are TAA compliant; NUE has resale agreements with ADS and Noble, is onboarding with Atlas Advisors on WEXMAC, and works through SWMAC with the Defense Innovation Unit. GPC purchases are accepted directly.
What’s the cycle life of a SunCase?
3,000+ cycles to 80% capacity with prismatic LiFePO₄ cells (6,000 on the 3651). NUEPower LiFePO₄ batteries offer up to 20× the cycle life of lead-acid at about 60% of the weight.
Can a SunCase go on military aircraft?
Yes, subject to standard lithium transport rules and packaging (UN38.3, IATA DGR, DoD airlift rules). NUE is working with the Department of War on streamlined approvals for larger systems.
Is the SunCase MIL-STD-810 certified?
SunCase is engineered to MIL-STD-810H environmental targets, with the Arctic configuration tested to −40 °F; formal documentation is in process. The DIU / U.S. Army energy nodes arriving July 2027 are MIL-STD-810 certified.
