While assessors may look over paperwork, that does not actually mean those involved in testing know what the standard to which they are testing actually says or if they do that they actually test to them. Cannot tell you how many times I review reports from supposedly accredited labs and see that the test results make no sense or are just flat wrong. It is not just from one economic area either, it seems almost pandemic sometimes.

CISPR 22, CISPR 32, CISPR 24, ANSI C63.4. Really disturbing when you see key things that aren’t set up properly. It makes you wonder what the qualifications are of the on-site assessors. Paperwork is usually fine, the assessors understand ISO/IEC 17025. Ghery S.

By that, I mean that the labs often have a little subsection which is tasked with doing nothing but expanding the range of accreditations; these are the chaps who paper entire hallways with certificates of accreditation, allowing you to take comfort that if you ever needed a machine safety certificate for Kleptostan, you were already in the right place. A certain disconnect exists between these certificate harvesters (think marketing) and the other part of the lab (think engineering) which actually has to do that rare and idiosyncratic test.

One accrediting body seems interested in dealing with the issue, the others not so much. It’s so much fun to go into a lab that isn’t properly equipped to perform tests listed on its Scope of Accreditation. Ghery S.

Ed Price WB6WSN Chula Vista, CA USA From: Doug Smith [mailto:d...@emcesd.com] Sent: Sunday, December 14, 2014 3:49 PM To: EMC-PSTC@LISTSERV.IEEE.ORG<mailto:EMC-PSTC@LISTSERV.IEEE.ORG> Subject: [PSES] Brick power supplies and test errors (two topics) Hi All, When I was at Auspex Systems (1996-2001) we had 8 EMC radiated emissions tests performed on our equipment (three 1500 lb cabinets full of disk drives). Of these, 4 tests had significant test errors, two major and two minor errors, but all had a large impact to our company! The tests were done at three different labs over time, all made at least one error. "Trust but verify."
