I hesitate to remind you all, but if anyone has a problem "interpreting" the requirements of IEC 60950, there is the TC74 Chairman's Advisory Panel.
Briefly, the procedure is as follows : Questions for interpretation should, as a minimum - define the problem, making reference to a specific subclause or subclauses of the Publication and, where appropriate,include a sketch; - provide an explanation of the actual situation that initiated the need for interpretation; and - be phrased, where possible, to permit a specific "yes" or "no" answer. Requests for interpretation of test results will not be considered by the Panel. Questions for interpretation should be submitted initially to the appropriate National Committee for TC74. Those that cannot be handled by the National Committee are forwarded to the Secretary of TC74. The Secretary of TC74 refers the Question to the Chairman of the Panel. ...and it goes on. I have personally had a request for interpretation answered, to the effect that : The unanimous Opinion of the Chairman's Advisory Panel is that the apparent difference represented by the words "overbalance" and "tip over" (in 4.1 stability requirements) is an editorial accident and that all three requirements are the same.
