Re: [PSES] Accreditation for standard comprehension?
The only ones that come to mind are ISO audits, and the contractual requirements between you entity and the NRTL/NB you engage to provide your certifications. These only require that you possess the standard in question and employees can locate it when necessary, thereby establishing familiarity. None that I know require any demonstration of competence. NRTL's must establish competence, and adequacy of their facilities, to their auditors.

Date: Mon, 11 May 2015 23:15:53 + Does anyone know of any conformance assessor certification schemes that have provisions requiring the applicant to demonstrate familiarity with the standards to which they will be assessing? I am familiar with a couple lab certification schemes that appear to focus on general business practices and professional qualifications and rigor of assessment, but not necessarily needing to demonstrate the assessor knows well what the standard requires.

[PSES] EMC and Data Center
Dear experts, Could you please share your knowledge about a philosophical or logical approach to EMC testing of a data center. To simplify my question let's talk about just EMI testing for USA. A data center contains computer systems and associated components, such as https://en.wikipedia.org/wiki/Telecommunication telecommunications and https://en.wikipedia.org/wiki/Computer_data_storage storage systems, air conditioning, fire suppression and various security devices. Servers are mounted in https://en.wikipedia.org/wiki/19_inch_rack 19 inch rack cabinets. Some equipment such as https://en.wikipedia.org/wiki/Mainframe_computer mainframe computers and https://en.wikipedia.org/wiki/Computer_storage storage devices are often as big as the racks themselves, and are placed alongside them. Should I test just one rack of a type on the turn table for RE? How many racks should be tested together for CE? Or just one? What standards are to be applicable for this situation? FCC? Bellcore GR-1089? Both? More? Thank you for your time and help. Best regards, Eugene - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.

[PSES] Generic Verses Product Standards
Experts, I was taught that when using harmonized standards to justify Presumption of Conformity, you must use the most relevant standard to your product/application. So if there is a product/family standard that obviously applies to your product, you should use it as opposed to a generic standard. Is that documented? Or is it just a rule of thumb?

Neither, really. A product (-family) standard 'takes precedence' over a generic standard, but in principle a manufacturer can apply any standard and then seek to justify the choice in the EMC assessment. -- OOO - Own Opinions Only.
