Does anyone know where I can find a copy of IEC 61558 (safety standards and testing standards for transformers)? I know that you can buy these for much $$ at your local bureau of standards, but coughing up $250 for a PDF without knowing what's in it is ludicrous. Especially after you've seen that much of the later added EN-additions only contain spelling fixes..
