1.2 This standard does not evaluate the performance or reliability of these devices.
1.3 This standard does not include requirements for the evaluation of EESAs intended for use in electric
vehicles, such as on-road passenger vehicles intended for use on public roadways including highways
and heavy duty off road vehicles such as battery powered ride-on industrial trucks, which are covered
under the Standard for Batteries for Use in Electric Vehicles, UL 2580 / ULC-S2580.
1.4 This standard does not include requirements for evaluation of EESAs intended for use in light electric
