Is there any time limit on how long a test result is valid for an EMC test - if the product hasn't changed. CB reports have a 3 year shelf life, after which the various CB participants are obligated to take the reports on face value and could require inspection or retest, but I don't know if the same is true for EMC test when meeting the EU directives. Actually I guess the requirement for a CB update every three years isn't truly a requirement for meeting the directives either. The CB report is a tool to help show conformity.
Bottom line the last EMC test was in 2004, and the clock speeds are pretty low - 12 MHz, so I don't think even the new upper frequency test range requirements of EN55022 affect the results. I'm inclined to test, the customer is not. Gary McInturff Reliability/Compliance Engineer Esterline Interface Technologies Featuring ADVANCED INPUT, MEMTRON, and LRE MEDICAL products 600 W.
