Ralph,
If a product self-recovers without operator intervention, then you can say it meets criterion B. The manufacturer has the ability within these criteria to define the acceptable loss of function, as well. If 1 minute is an acceptable time for the self-recovery, the product passes. If operator intervention was required, then a clear failure of criterion B would exist. Ghery Pettit From: Ralph McDiarmid [mailto:[email protected]] Sent: Wednesday, April 23, 2003 5:01 PM To: 'EMC-PSTC' Subject: Performance Criterion I have a question about Performance Criterion B as described in EN61000-6-2. Scenario: A product temporary looses communication over a network connection during an EMC disturbance like an ESD event. It self-recovers and resumes communication after about a minute. Question: Is the above event considered an acceptable loss of performance or a loss of functionality? If it is a loss of functionality, even a temporary one, then I would say that is fails Criterion B, but meets Criterion C. I don't think it a question of loss of performance in this example. Is this a correct interpretation? Thanks, Ralph McDiarmid, AScT Compliance Engineering Group Xantrex Technology Inc.
