Example
Vehicle and transport standards: an example situation
Shipping tests and vehicle battery approval tests address different uses; passing one does not automatically satisfy another.
Read GTR 20 alongside IEC 62660 in this context. The international standard series for lithium-ion cells in electric vehicles: part 1 performance testing, part 2 reliability and abuse testing, part 3 safety requirements. It fixes test conditions so results from different labs can be compared.
