Success means the team consistently identifies inflection points in cell pricing, supplier health, and policy enforcement weeks or months before they surface in earnings calls, annual surveys, or trade press. The commercial mechanism is internal-first: the publication proves itself as a decision tool inside the organization, then extends to paid subscribers and a practitioner community as upside. Revenue follows utility — if the team makes better-timed procurement calls and competitive assessments because of what they read here, the publication earned its place. [Read on the website]() ## Issue 6 — Qualification Pack-level requirements, test conditions, and standards by application ### Evidence Scope Map - [The Evidence Ladder — What Each Standard Actually Qualifies]() — By [Ronan Adike]() · Published 2026-07-17 · Format: The Standards Map Most pack-level DVP rows cite a standard. Fewer establish that the standard was written for the application, the parameter class, or the operating profile the row claims to cover. This piece maps the evidence picture for eVTOL, drones/UAS, UUV/subsea, and humanoid robotics against a six-rung ladder running from transport eligibility through regulator acceptance. The primary output is what each cited standard does not establish. That finding carries the same structural weight as governed requirements, because the DVP row that unravels at qualification review is the one backed by a borrowed citation nobody scoped. ### Standard Scope Cards These eight cards run by standard name rather than by application. The inversion is deliberate. The costliest DVP errors happen at the standard-selection layer, when a document gets cited for a question it was never scoped to answer. Transport compliance standing in for operational safety. A portable-scope standard applied to an industrial pack. An aircraft MOPS treated as propulsion-battery thermal-runaway closure. Each card carries what the standard establishes and what it does not. That second line is load-bearing. Category errors at this layer compound quietly for months before surfacing in a qualification review. All citations traced to published sources and verified July 2026. Where a standard leaves a void, the card names it. Where scope is borrowed from an adjacent domain, the borrowing is labeled. - **UN 38.3 Rev.8 Governs Transport Not Operations** — [Source]() — Published 2026-07-17 Tag: Transport Baseline Rev.8 (2023), Amendment 1 (2025) per UNECE. Establishes: transport eligibility for lithium cells and batteries under 49 CFR 173.185. Does not establish: operational safety, installed-system qualification, or application suitability. Every application cites this as transport baseline. Last verified July 2026. - **IEC 62619 Sets Industrial Safety Not Duty-Cycle Qualification** — [Source]() — Published 2026-07-17 Tag: Industrial Safety Ed. 2.0, published May 2022, stability date 2026. Establishes: safe-operation requirements and tests for industrial lithium batteries. Does not establish: application-specific duty-cycle qualification. Where a special-application IEC standard exists, it takes precedence. Borrowed by humanoid robotics, industrial drones, UUV programs lacking a dedicated standard. Last verified July 2026. - **IEC 62133-2 Covers Portable Packs, Not Industrial** — [Source]() — Published 2026-07-17 Tag: Portable Safety Ed. 1.1 (A1:2021), stability date 2026. Establishes: safety for portable sealed secondary lithium cells under intended use and reasonably foreseeable misuse. Does not establish: industrial-application or installed-system qualification. "Portable" is a scope qualifier with real consequences; confirm the characterization before citing. Borrowed by small drones, portable robotics packs. Last verified July 2026. - **ASTM F3005-22 Covers sUAS Packs, Stops at Aircraft** — [Source]() — Published 2026-07-17 Tag: sUAS Packs Active, published 2022. Establishes: battery-pack design, mechanical, electrical, and maintenance requirements for sUAS. Does not establish: installed-system or aircraft-level qualification. Scope explicitly excludes requirements for the systems in which these packs operate. Borrowed by drone and UAS programs. Last verified July 2026. - **DO-311A Addresses Aircraft Batteries, Not eVTOL Propulsion** — [Source]() — Published 2026-07-17 Tag: Aviation MOPS Current RTCA revision, referenced in EASA MOC-4 SC-VTOL Issue 2 (2025-07-11). Establishes: MOPS for rechargeable lithium batteries powering aircraft systems and equipment. Does not establish: propulsion-battery thermal-runaway containment for eVTOL. EASA states explicitly that its thermal-runaway test did not consider electric or hybrid propulsion batteries. MOC VTOL.2440 layers additional installed-system requirements on top. Last verified July 2026. - **ISO 20682:2026 Excludes AUV Batteries From Scope** — [Source]() — Published 2026-07-17 Tag: Gap Marker Published February 2026. Covers AUV risk and reliability in the underwater domain. Establishes: no battery-pack requirement whatsoever. Explicitly excludes batteries for AUVs, electrical motors for AUVs, and autonomous underwater gliders. Pack qualification for UUV programs remains entirely program-defined. Pressure envelopes, thermal rejection, abuse tolerance, containment: all fall to the DVP owner. Last verified July 2026. - **MIL-PRF-32565 Specifies 6T Li-Ion for Ground Vehicles** — [Source]() — Published 2026-07-17 Tag: Defense Ground Document date August 2022, DLA metadata updated July 2026, active. Establishes: performance requirements for rechargeable sealed 6T lithium-ion batteries under STANAG 4015 covering SLI, deep-cycle, and silent-watch roles. Does not establish: qualification for non-ground-vehicle military applications. FAT completion, QPL listing, and Section 4865 sourcing proof are separate evidence gates. Last verified July 2026. - **ISO 13482 Governs Robot Safety, Not Battery Packs** — [Source]() — Published 2026-07-17 Tag: Robot Safety Published 2014, confirmed 2020. ISO/FDIS 13482 Edition 2 at Stage 50.00, publication expected imminently. Establishes: safety requirements for personal care robots. Excludes robots traveling >20 km/h, flying robots, industrial robots, medical robots, military robots. No battery-pack test conditions, C-rate thresholds, cycle-life criteria, or abuse tests appear in scope. Humanoid programs borrow it for hazard-framework context only. Last verified July 2026. ### UUV Gap Marker - **ISO 20682:2026 — Autonomous Underwater Vehicles — Risk and Reliability** — [Source]() — Published 2026-07-17 Edition 1, published February 2026 under ISO/TC 8/SC 13. Covers AUV risk and reliability for sensors and communications. Scope explicitly excludes batteries for AUVs, electrical motors for AUVs, and autonomous underwater gliders. No working group within the standard carries battery-pack requirements. The exclusion is a deliberate scope boundary, not a deferred annex. Why is the exclusion structural? The freshest AUV domain standard actively bounded away from the battery interface. No ISO body claims UUV pack qualification scope as of February 2026. What does "program-filled gap" mean here? Every pack-level pressure, thermal, and abuse parameter is DVP-governed. The DVP is the primary document, not gap-fill for an incomplete standard. - **NAVSEA S9310-AQ-SAF-010 Rev 3 — Lithium Battery Safety Program (LBSP)** — [Source]() — Published 2026-07-17 NAVSEA's LBSP certifies lithium batteries as energy devices for Navy vessel use. The document states environmental qualification testing, including UUV depth-pressure conditions, runs as a separate process. LBSP completion does not constitute pressure, shock, vibration, or EMI qualification. Depth-pressure acceptance criteria are established at the platform or program level. Where does LBSP stop? Lithium safety certification only. UUV pressure qualification is a parallel track governed entirely by program-level requirements, not LBSP. Does any public NAVSEA document specify pack pressure acceptance criteria? No. The program DVP defines them, reinforcing the same program-filled gap seen in ISO 20682's exclusion. - **ISO 21173:2019 — Hydrostatic Pressure Testing for Submersible Pressure Structures** — [Source]() — Published 2026-07-17 Governs hydrostatic pressure testing for pressure hulls and buoyancy materials of manned and unmanned submersibles. Scope covers structural integrity of the pressure vessel. Electrolyte behavior under pressure cycling, connector leakage thresholds, thermal rejection at depth, cell output stability, and post-thermal-runaway gas venting inside a submerged enclosure all fall outside its scope. What does ISO 21173 actually prove? That the housing holds pressure. Not that the battery pack inside it operates safely, thermally manages, or contains failure products at depth. Can you borrow its methods? Enclosure proof-pressure testing, yes. But acceptance criteria for pack internals under sustained depth pressure remain entirely DVP-owned. - **MIL-STD-810H Method 512.7 — Immersion Testing** — [Source]() — Published 2026-07-17 Method 512.7 evaluates enclosure integrity and product performance when submerged, with provisions for pressure-vessel testing beyond 1 meter depth. Commonly borrowed for UUV battery enclosure sealing validation. Does not address cell behavior under sustained pressure, thermal rejection while submerged, electrolyte containment after cell failure, or electrical output stability during pressure excursion. What does Method 512.7 establish? Enclosure water ingress resistance. It says nothing about operational battery safety, thermal management, or abuse behavior at depth. What's the borrowing risk? A DVP row citing MIL-STD-810H Method 512.7 for UUV battery qualification overstates the standard's governing scope by a wide margin. ### Settled-Lane Contrast - [MIL-PRF-32565 and the evidence ladder's missing rungs]() — By [Ronan Adike]() · Published 2026-07-17 MIL-PRF-32565 governs rechargeable sealed 6T lithium-ion batteries for ground vehicles.
