John, Glad to see that you have started a new thread so that we may start afresh.
In fact, in an earlier reply to Art Michael I did make a passing reference to OSM decisions relating to EN 60950. However, this may have been too brief or obscure for you to notice. Although I have never worked in a test house and so cannot comment from personal experience, I understand that the Operational Staff Meeting (OSM) of the CENELEC Certification Bodies (CCB) operates in a similar way to the CTL within the IECEE as regards discussing testing matters. Perhaps one of the people who are members of this group would care to confirm or correct this statement? It does seem that there is no universal way of confirming OSM decisions with the relevant CENELEC Technical Committees, or CTL decisions with the relevant IEC Committees. Up until recently, IEC/EN 60065 was developed by TC92 and IEC/EN 60950 was developed by TC74: now both standards are the responsibility of TC108 and it is possible to see that slightly different procedures were in place to deal with these standards. As it happens, representatives from test labs were active in both TC74 and TC74 and they continue to be active in TC108 and so for IEC/EN 60065 and IEC/EN 60950 there is a good linkage between the standards makers and the test and certification bodies. This does seem to result more from serendipity rather than an overall grand plan, however. I would hope and expect that the OSM has a way of communicating their documents to the CTL. Not being a member of either organisation I could not say if this a formal or informal arrangement. Again, a reply from someone who works for a test lab and is aware of the procedures would be nice! Perhaps you could use your internal contacts within the ERA to check out the situation with other standards? Certainly, within TC76, dealing with IEC/EN 60825, there have been no CTL decisions discussed in the time that I have been attending IEC meetings. However, the only CB scheme for that standard series relates to IEC 60825-2 and that scheme is little used. Best regards and Merry Christmas, Richard Hughes
