4.1 ANSI/ESD S11.31 ESD Association standard for evaluating the performance of electrostatic
discharge shielding materials - Bags
This test method evaluates the performance of electrostatic discharge shielding bags. The purpose of
this standard is to ensure that testing laboratories, using this test method to evaluate a given
packaging material, will obtain similar results.
This standard specifies the discharge waveform characteristics, probe configuration, probe
capacitance and bag size. Figure 4-1 shows the generic schematic of the test system configured for the
energy test.

Figure 4-2a shows the discharge current waveform requirement at the specified 1000 Volts when
measured with R2=0, a short to ground.
