ISO 19453-5:2018

Road vehicles — Environmental conditions and testing for electrical and electronic equipment for drive system of electric propulsion vehicles — Part 5: Chemical loads

ISO 19453-5:2018 specifies requirements for the electric propulsion systems and components with maximum working voltages according to voltage class B. It does not apply to high voltage battery packs (e.g. for traction) and systems and components inside. It describes the potential environmental stresses and specifies tests and requirements recommended for different stress levels on/in the vehicle. ISO 19453-5:2018 describes chemical loads. NOTE Conditions and testing for a continuous contact can be determined from other standards or agreed upon between the customer and the supplier.

Foreword
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 of
electrotechnical 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
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

Part 5:
Chemical loads
1 Scope
This document specifies requirements for the electric propulsion systems and components with
maximum working voltages according to voltage class B. It does not apply to high voltage battery packs
(e.g. for traction) and systems and components inside. It describes the potential environmental stresses
and specifies tests and requirements recommended for different stress levels on/in the vehicle.
This document describes chemical loads.
NOTE Conditions and testing for a continuous contact can be determined from other standards or agreed
upon between the customer and the supplier.

4 Tests
4.1 General
Components and associated parts that can come into contact with the specified chemical agents shall
be resistant to those agents. The components and associated parts shall be tested with all agents they
are likely to come into contact with, except for those materials which can be shown by documentary
evidence to be immune to the contaminant and which need not be tested.

ISO 19453-5:2018(E)

A material is considered to be immune to a contaminant if there is no change in properties sufficient to
affect material performances over the time and at the temperature specified in this clause.
The supplier and vehicle manufacturer shall agree on the manufacturer and type of chemical agents.
Resistance to the specified chemical agents shall be considered as early as possible during the material
selection process.
4.2 Purpose
The purpose of the test is to determine whether the device under test (DUT) is unacceptably affected
by temporary exposure to contaminating agents.
NOTE This test is not intended to be a life test.
4.3 General test conditions
Chemical agents shall be selected as defined in Table 1, depending on the mounting location of the DUT.
Unless otherwise specified, one DUT per test agent shall be used.
The following tests describe one test cycle. Unless otherwise specified, one test cycle with one agent
per DUT shall be performed. Any other number of cycles may be agreed between the customer and the
supplier.
NOTE If the size of the DUT is sufficient, multiple test agents can be applied partially on one DUT provided
that these do not have any influence on each other.
4.4 DUT conditioning
Unless otherwise specified, the DUT shall be stored at a room temperature (RT) of (23 ± 5) °C and a
relative humidity (RH) of between 25 % and 75 % until temperature and humidity are stabilized.
The DUT shall be tested under conditions of normal use. If necessary, and unless otherwise specified,
unrepresentative coatings or contaminations of the DUT shall be removed.
If a cleaning procedure is needed, the customer
