Hi Vincent:
I’m a cynic regarding certification houses such as VDE and UL. Their primary motive is income in the name of safety (not necessarily actual safety). 4) Does it mean that components that meet VDE Mark and meet UL Recognized Mark without much testing to be done? Example, a Li-ion battery which is IEC / EN 62133:2012 certified with VDE Mark, does it mean that it can meet UL Recognized Mark requirement with just little or no extra testing to be done? With the advent of IECEE, members must recognize competitors’ certifications, which means little or no income from testing and certification. Members do their best to find problems with others’ testing so that they can re-do the testing and derive some income. National deviations from an IEC standard provide another opportunity to test and derive income (if the original CB report did not cover the national deviations). So, the answer is, “it depends.” If there is no CB report, then VDE and UL testing are independent of each other. If there is a CB report, the other member will evaluate it and give you its finding whether the CB report meets the standard’s (their interpretation) requirements (and local, unwritten requirements of the test house). (Providing a copy of the non-CB test report will probably make it easier for the other test house to test the unit and more timely, but probably will not make it less expensive.)
