Safety testing

Thermal, mechanical, electrical, environmental, and abuse risks manifest differently by level. A test plan should state object, use condition, failure mode, method, and decision criteria, avoiding material-level screening as pack-level safety proof.

The same test can yield different results with different state of charge, temperature, aging, or structure. Reports should record sample origin, count, revisions, preconditioning, and equipment state so third parties understand coverage and non-transferable parts.

Both anomalous and passing results need translation into risk controls, design change, process improvement, or use limits. Reporting only pass without conditions, limitations, and follow-up does not support product change or user safety decisions.
