Greetings folks. I'm in the process of working out what tests need to be performed on a particular product for compliance with EN61010-1.
The item in question operates from a DC supply. For determining the test level required for impulse withstand, I need to determine which Installation Category (Overvoltage) Category is applicable. Unfortunately, the standard only provides AC supply voltages (phase-to-earth voltage) in its table for determination of the applicable category. The installation category selection is based on IEC 664. Is there anyone who has encountered this problem with EN61010-1 or IEC 664 who can offer advice? Thanks in advance, Peter Poulos Hardware Development Engineer Foxboro-L&N (Australia) Ph: +61 7 3340 2118
