Ron, Within the past year, I have not had any trouble getting BABT to accept EN60950 in lieu of BS6301. The only EU member that still insists on EN41003 instead of EN60950 is Finland's PTT. (And this is as recent as last week.) I tried to fight it the first couple of times and couldn't get anywhere, so now I just prepare a DOC for Finland that includes EN41003 on it along with EN60950. By the way, can someone help educate me on the K.21 requirement for lightning surge for TE? Why have most European countries dropped this, but Switzerland, the Czech Republic, and Italy still require it? Section 9 a) says "TE that employs insulation spacings that are dimensioned and tested in accordance with IEC 950 need not be subjected to further tests under this Recommendation". Does this mean that my EN60950 approval is adequate? There is also a notation that the test voltage may be different in different countries to meet local requirements, so perhaps EN60950 isn't sufficient in some countries. If it's determined that I really do need K.21 - (Lightning surge), do any of you know which labs in the U.S. can test to this? Regards, Debbie Olson Boca Research
