Koh Beware, the 6th edition of IEC60065, clause 4.3.10 calls for a fault conditions test whereby each group of ventilation openings is blocked in turn. Groups of openings are defined as 1) those on the top and 2) those on the sides and back excluding the front. It sounds like your product would fail this test.
