Interesting question, I have always gone under the assumption that the requirement would be the same for all levels tested up to the maximum voltage. I of course have no hard proof that this is the actual requirement.

ESD requirement of +/-8 Kv Air Search and +/- 4 KV Contact/Indirect is usually tested gradually for example +/- 2KV, +/- 4 KV and +/- 8KV. EN 55024 calls out for performance Criteria B. The question is: Is the performance criteria the same for all voltages tested ? For example is it also performance criteria B for the voltages below the maximumm requirement or does it roll up to performnce criteria A for less then max requirement. I hope I have phrased the question correctly. Thanks in advamnce for any responses. Sandy Mazzola Sandy Mazzola Regulatory Engineering Symbol Technologies Inc.
