Re: [PSES] Questions on GS, VDE and UL Recognized Marks
Dear all: I apologize for my unkind characterization of VDE and UL. Rich From: Richard Nute [mailto:ri...@ieee.org] Sent: Monday, January 02, 2017 10:49 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] Questions on GS, VDE and UL Recognized Marks 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.)

[PSES] Questions on GS, VDE and UL Recognized Marks
Hi all, Happy 2017 1) Am I correct to say that GS Mark applied to finished goods while VDE Mark applied to semi-finished goods, e.g. parts, components ? 2) Starting from mid 2016, what are the reasons for accepting only test reports issued by ZLS accredited test lab when come to GS Mark application? Remember before mid 2016, testing at ZLS accredited test lab is not a must for GS Mark application/ 3) If VDE Mark applied to semi-finished goods, e.g. parts, components, then what is the difference between VDE Mark and UL Recognized Mark (which applied to components and semi-finished goods too) ? 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? Hope to hear from you soon. Thank you and have a blessed 2017. Regards, Vincent - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
