We measure a few degrees too high temperature on a power component inside the product, when the ventilation holes in the chassis are blocked (abnormal condition).
Draft verdict from test lab is FAIL. Our claim is that such abnormal condition will not happen due to: * Product installed by skilled and trained technical persons. * Product installed in racks / environment that make it impossible for such blocking. The product is placed in closed premises with fences covering the premises. It’s part of international aircraft navigation system. Question: Is it reasonable to require such an abnormal condition test, when that a situation is not practical to happened in real life? Thanks!
