21.3 Test Procedures
Testing shall be performed sequentially starting with handling tests followed by powered and direct access tests. Before
testing commences, the discharge voltage of the ESD simulator shall be verified at the levels listed in Tables 21-1 and 21-2.
• Between individual discharges, the remaining charge shall be bled off using the bleed-off resistor (approximately 1M
ohm resistance) by touching the discharge point and the ground plane. This step is particularly critical for devices with
decorative chrome trim.
• Charge dissipation between discharges of some modules (instrument panels, large plastic modules etc.) may require use
of an ionizer. If used, the air ionizer shall be turned off and removed before each discharge is applied.
• When testing is completed, parametric tests shall be performed to verify that the DUT meets the requirements
delineated in Tables 21-1 and 21-2. Parametric testing shall be performed before commencement of any subsequent
testing.
