BS IEC 61340-4-8:2010 Electrostatics. Standard test methods for specific applications. Discharge shielding. Bags

BS IEC 61340 provides a common, repeatable method for testing and determining the shielding abilities of electrostatic shielding bags.

This test method improves upon existing test methods for static shielding by controlling some of the variables that were not previously addressed such as:

– Discharge waveform characteristics;
– Capacitive probe capacitance;
– Bag size.

This test method has also made a significant change by discontinuing the use of two voltage probes and incorporating a single current probe for measurement purposes. This was done to eliminate the problems that were encountered with attempting to balance the voltage probes which resulted in measurement errors.

The purpose of this standard is to ensure that testing laboratories who use this test method to evaluate a given packaging material will obtain similar results.
