Hi Pat, Thanks for your clarification. One question about the amendment from IEC.
EN 60950-1 2006 EN 60950-1 2006 A11 2009 EN 60950-1 2006 A1 2010 EN 60950-1 2006 A12 2011 EN 60950-1 2006 A2 2013 According to OJ, all A11, A1, A12 & A2 are the amendments to EN 60950-1. Normally, CENELEC issuing amendments based on IEC is a routine process. How can IEC amendments become CENELEC standard directly?
