If you are populating a UUV pack DVP and looking for the ISO number that anchors it, there isn't one. The exclusion is written into the documents themselves.
ISO 20682:2026, AUV risk and reliability, published February 2026, states in its public scope that batteries and electrical motors for AUV use are excluded. ISO 21173:2019 (confirmed 2025) governs hydrostatic pressure testing of pressure hulls and buoyancy materials, not battery packs.
Class fills the space. Marine classification societies write the technical rules and survey against them, one body holding a function that aviation splits between the regulator and the standards body. ABS §10/11.5 (January 2025) addresses lithium installation, BMS functions, and pressure exposure directly.
For your DVP, that means class rules define which demonstrations are required without setting the thresholds those demonstrations run against. Design depth and mission duration remain program inputs.

Three authority chains, compared
eVTOL: FAA AC 20-184 / EASA SC-VTOL MOC → DO-311A, ASTM F3830-26 as accepted means of compliance. Regulator on top, standard underneath.
Drone/UAV: Regulator points directly at IEC 62619:2022 and ASTM F3005-22. Standards body is primary.
Subsea/AUV: ABS or DNV class rules are top and substance. IEC 62619 and UN 38.3 appear inside them as referenced baselines, not as coordinate authorities.
Not ABS-specific. DNV publishes parallel AUV rules (Underwater Technology, Pt.5 Ch.8, 2021 edition). IACS has 12 member societies operating equivalent structures.
Why class got there first. DNV GL's 2016 maritime battery handbook stated plainly that no international standards existed for large maritime batteries. Class rules filled that gap and still hold it.
Still program-defined under class: design depth value, mission duration, thermal rejection path, acoustic constraints, post-abuse containment, connector leakage acceptance.
