I haven't heard of any recent discussions about tolerance or of uncertainty, but a couple of decades ago, the measurements were compared to the limits or declared values with no consideration of tolerances. AND then, if the object came under surveillance, and the measured value was within the tolerance or uncertainty, no problem. If it exceeded the tolerance, the inquiry began. This has something to do with statistics and which end you apply the flexibility with subsequent results.

I have learnt that there is a new interpretation discussed in EU countries recently that the manufacturer/importers cannot use the tolerances in the measurement to support the declared values. The measured values must fall into the range of declared rating without the use of tolerances. Have anyone learnt about that and any detail why the tolerances are solely used by market surveillance? > >Thanks and regards, > >Scott - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
