ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters ofelectrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the

Electrically propelled road vehicles — Safety
AMENDMENT 1: Withstand voltage test for electric power
Add the following terminological entry:
electric power source
system that provides electric energy
EXAMPLE RESS, fuel cell system, photovoltaic system.
Add following text after the second paragraph:
Electric power sources, which can be de-energized, shall be de-energized and included into the balanceof the electric circuit.
Electric power sources, which are not part of the balance of the electric circuit shall be tested accordingto 10.7.
Add the following subclauses after 10.6 and before the Bibliography:
10.7 Withstand voltage test for electric power sources which are not de-energized10.7.1 General
This test is intended to demonstrate the adequacy of the protection measures to isolate live parts ofvoltage class B electric circuits.
It applies to voltage class B electric circuits of electric power sources that are not conductivelyconnected to a voltage class A electric circuit or to the electric chassis.
The test may be performed at the vehicle level at the discretion of the vehicle manufacturer.© ISO 2020 – All rights reserved 1

For this test, device under test (DUT) refers to a voltage class B electric power source that cannot bede-energized.
The voltage withstand test for the components of DUT (e.g. control unit, contactor) can be performed
separately unless it affects the test results. For components of the DUT which are de-ener...
