Road vehicles—Environmental conditions and testing for electrical and electronic equipment for drive system of electric propulsion vehicles—Part 5: Chemical loads
Road vehicles — Environmental conditions and testing for electrical and electronic equipment for drive system of electric propulsion vehicles — 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 describes the potential environmental stresses and specifies tests and requirements of chemical loads recommended for different stress levels on/in the vehicle.
This document is applicable to the electric propulsion systems and components with maximum working voltages according to voltage class B.
This document does not apply to high voltage battery packs (e.g. for traction) and systems and components inside.

3 Terms and definitions
For the purpose of this document, the terms and definitions given in GB/T 42284.1 apply.
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. 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 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.
Manufacturer and type of chemical agents shall be agreed upon between supplier and customer. The composition description listed in Annex A is for reference.
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
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%. Chemical agents shall be selected as defined in Table 1, depending on the mounting location of the DUT. 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.
