Busy last week, including the PSES Symposium (a good show, BTW; I reccommend attending and participation in future symposia). A few delayed responses follow in this thread. Regards, Peter L.

Some of the OSM decisions are identified as effective for only specific EU member nations and not all member nations. Your statement that "all test-houses across Europe apply the standards in the same way," only adds mud to an already unclear process. I'd appreciate a little more education. > >Though I have not been involved with products I > knew were intended for > >sale to governmental bodies, I suspect the OSM > Decisions can come into play. > > Not unless your product involves one of the > situations which prompted an OSM decision. Forgive me, here, but for the life of me, I can't imagine a case where one might be required to apply any given OSM Decision where it doesn't apply.

Perhaps I'm being picayune, but if an OSM Decision applies in only a few EU member states, rather than in all member states, no matter what anyone attempts to name the item, it has all the smell, taste and color of a National Deviation or Group Difference. Sometimes, based on national laws, they have that ultimate effect, irrespective of any fondness for claiming they are not National Deviations or Group Differences. The following statement can be misconstrued. It is not intended to offend or disparage. For all the criticism Canada and the USA have received for including installation code based national differences and national laws (meaning, there are lots of them), they are, at least, not located entirely outside our national standards and are duly noted in CB Scheme Test Reports (which leads me to conclude they are also in the CB Bulletin). In a separate e-mail, I will provide an anecdote that illustrates my position. If holes can be shot in the proposition, I welcome the information.
