[PSES] ESD Table Top Testing Bench with IEC 61000-4-2

2017-04-06 Thread Harris, Kevin J (DSC)
Dear Colleagues, We made a decision to renovate our laboratory with new lab benches. This has led to a bit of a conundrum with our ESD benches. Our local Feng Shui expert has proclaimed that it would not do to have all new lab benches except for our old ESD wooden benches. The issue we keep

Hi Grace For your point 2 Under the RE-D for EMC compliance, you are not required to use a notified body if a particular standard is not listed in the OJEU. See Articles 3(1)(b) and 17(2) of the RE-D http://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX:32014L0053=EN Kind regards

Perhaps trust may be an issue, but given that the current system of humans making the decisions kills more than 3,000 people a day according to https://asirt.org/initiatives/informing-road-users/road-safety-facts/road-crash-statistics surely we could get over it Kevin From: Ken Javor

Hello All Have I misunderstood the words in IEC62052-31? In a hypothetical measurement of an applied voltage where the uncertainty of the exact value is 1% and a test voltage of 100 is required, the manufacturer would need to insist on a 101V test voltage and the test facility would have to

Hi David There is no 2013 version of EN50130-4. The last full version was in 2011, followed by a 2014 amendment (A1) Although A1 was voted positively over a year ago, the European commission has still not yet managed to actually post the document in the OJEU! Technically speaking for the

All, I have consulted with TC 72 (the authors of the EN 54 series) and they are well aware of the problem. The long term goal is to update those parts with the dated references but in the meantime I have the following quote from the committee TC 72 works closely with the group of notified

Brian, That guidance is not quite applicable here. Only EN 50130-4 is listed in the OJ as an EMC standard and so can be the only standard used for presumption of conformity. The EN 54 series is a product performance set of standards and the requirements contained therein technically have no
