Impact test
Dropping a 9.1 kg mass from 61 cm onto a 15.8 mm steel bar laid across a cell, to simulate a crushing blow. In UN 38.3 test T.6 it applies to cylindrical cells of 18 mm diameter or more — smaller round, prismatic, pouch and coin cells are crushed instead — and the cell must stay below 170 °C without fire or disassembly.
- Also called
- UN 38.3 T6, T.6 impact, bar impact test
Example
Testing methods: an example situation
Resistance immediately after a current step can differ from a ten-second value because slower polarization contributes.
Read Impact test alongside Abuse testing in this context. Deliberately driving cells and packs beyond their limits — overcharge, crush, nail penetration, external short, heating, drop — to see how they fail. Standards define each test and rank the outcome on a hazard scale from no effect to explosion.
Use in Lemonergy
