be made with the measuring junction of the thermocouple held tightly against
the component/location being measured. For those tests that require the sample
to reach thermal equilibrium (also referred to as steady state conditions),
thermal equilibrium is considered to be achieved if after three consecutive

20.5| Where there is a specific reference to a single fault condition in the
individual test methods, the single fault is to consist of a single failure
(i.e. open, short or other failure means) of any component in the personal e-
mobility devices that could occur and affect the results of the test. Faulting
over two redundant components that have not been determined to be independent
of each other is considered a single fault condition. This fault is
implemented in conjunction with the test being conducted (i.e. overcharge,
short circuit, etc.) or may be conducted as part of a verification of a
protective circuit. A protective device determined to be reliable may remain
in the circuit without being faulted. See Appendix A and 2.1. A protective
device determined to be reliable is one that has been shown to comply with an
appropriate component safety standard and is used within its ratings.| | P

20.6| The tests contained in this standard may result in explosions, fire and
emissions of flammable and/or toxic fumes as well as electric shock. It is
important that personnel use extreme caution and follow local and regional
worker safety regulations when conducting any of these tests and that they be
protected from flying fragments, explosive force, and sudden release of heat
and noise that could result from testing. The test area is to be well
ventilated to protect personnel from possible harmful fumes or gases. As an
additional precaution, the temperatures on surface of at least one cell/module

purposes. All personnel involved in the testing are to be instructed to never
approach the DUT until temperatures are falling and have returned to within
ambient temperatures.| | N/A
