TC 61 interpretation sheet on: Mechanical shock and vibration testing on large metal-
ion batteries of IEC 60335-1:2020
INTRODUCTION
Currently the standard mentions:
B.24.1 The relevant standards for non-acid based electrolyte cells employed in
batteries are IEC 62133-1:2017 for nickel systems and IEC 62133-2:2017 for lithium
systems.
NOTE The requirement for cells does not extend to the battery itself.
A battery that uses metal-ion chemistry shall additionally be subjected to the tests of
Subclauses 7.3.8.1 (vibration) and 7.3.8.2 (mechanical shock) of IEC 62133-2:2017.
When Annex B was written for the IEC 60335-1 edition 6, the batteries foreseen were for
portable applications and rather lightweight. The IEC 62133-2:2017 standard referred to is
applicable to portable lithium batteries only.
ICS 13.120, 97.030
IEC 60335-1:2020-09/ISH2:2025-08(en-fr)

For non-portable and/or large batteries (mass > 12 kg), the tests of IEC 62133-2 for
mechanical shock and vibration are not suitable.
QUESTION:
What test sequence for mechanical shock and vibration can be followed for large batteries?
ANSWER:
For practical reasons, IEC 60335-1 should follow the same differentiation as the UN 38.3
transport test or IEC 62281 standard (Safety of primary and secondary lithium cells and
batteries during transport).
For larger batteries with a mass exceeding 12 kg, Subclauses 6.4.3 (Test T-3: Vibration) and
6.4.4 (Test T-4: Shock) of IEC 62281:2019, including AMD1:2021 and AMD2:2023, may be
applied.
NOTE 1 The tests are technically identical to Test T.3 and Test T.4 of the UN manual of tests and criteria, section
38.3 rev.8 (2023).
NOTE 2 In accordance with Table 5 of IEC 62281:2019, testing is carried out on the battery without packaging.
