[PSES] OSHA - NRTL audit question
Was at an NRTL/CAB site yesterday. Noted a small group lurking - assessment engineer said they were part of an OSHA audit team. I recognized one member of the audit team from another NRTL down the road. Does the U.S. OSHA use NRTLs to audit each other?

[PSES] Temporary Measurement Sites
Many companies can not justify the cost of a measurement chamber for radiated emissions - not to mention the cost of an EMC engineer to run it. I completed an article on how I set up temporary radiated emissions measurement test sites in client buildings and offices. This may help you when you find the need to perform troubleshooting or pre-compliance testing prior to qualification testing at your own facility. http://www.tmworld.com/blog/The_EMC_Blog/41857-Temporary_RE_Measurement_Sites.php Cheers, Ken ___ Kenneth Wyatt Wyatt Technical Services LLC Woodland Park, CO Email Me! | Web Site | Blog The EMC Blog (TM World) Subscribe to Newsletter Connect with me on LinkedIn - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.

[PSES] Ergonomics Aspects - arrangement of TERMINALS in IEC 61010:2010
Greetings all, I would like someone to verify my thoughts in IEC 61010-1:2010 section 16.2 d) Ergonomics Aspects - arrangement of TERMINALS. This clause is a bit obscure (possibly incomplete) and to be honest makes no sense in the ways I have seen it used so far. This new section 16 is all about ergonomics and here we are suddenly we are referencing “terminals” again. In the Standard and in the TRF rev. H, the word TERMINALS is printed in the font small caps Arial, which indicates it has an official definition in the balloted portion of the standard. IEC 61010-1 section 3.2.1 defines TERMINAL as a “component provided for the connection of a device to external conductors”. My feeling is this subject is very well covered in sections 5, 6, 10 and Annex F and a reference is ergonomics seems out of place. Ergonomics has to do with hazards related to long term exposure of repetitive motions and activities. Therefore, this cannot be about a one-time or very infrequent task of installing of a wiring terminal which is hardly enough for repetitive stress injury. Note: There is no such thing as an ergonomics emergency. For the sake of clarification, the note in section 16 refers to these standards: EN 894-2, -3, ISO 9241, and SEMI S8. After re-reading each of these standards, I found “terminals” are always referring to Visual Display Terminals (VDTs); either CRT or flat panel types and with or without active touch surfaces. So I must conclude, in the section 16 of IEC 61010-1 “terminal” is about visual displays. Therefore, the test report form responses to “arrangement of terminals” should be along the lines of viewing angles, heights, or N/A. Is this the consensus? -- Thanks, -doug Douglas E Powell doug...@gmail.com http://www.linkedin.com/in/dougp01 - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.

These questions would serve as an automated pre screening mechanism.

Well don't try - what is the sound of one hand clapping I asked Siri (iPhone assistant thingy) and she gave me an answer. (Silence) Try to avoid definitions and work the question so they have to demonstrate knowledge of what things do. You might try, if you have inadequate creepage distances what alternatives might be available? (through insulation is what I had in mind) They can look up creepage distance all night long but unless they known a little something about what is being accomplished with creepage distance they can't come up with an alternative.

You could ask them for a hipot voltage per 5.2.2; I don't believe the table is available via google; you would also be able to evaluate their useage of the table, conversion from RMS to Peak voltage, AC vs DC, etc. You could also ask them to summarize the requirements for a fire or mechanical enclosure; things like that would require more experience than just reading 60950... -Ken On Tue, Jul 3, 2012 at 3:01 PM, John Woodgate j...@jmwa.demon.co.uk wrote: In message CADYqxLATv+**VVo4H2QFMuQXvY9jUgxbakOm4=fRz=**FMoMJAyc= q...@mail.gmail.com, dated Tue, 3 Jul 2012, Kevin Robinson kevinrobinso...@gmail.com writes: Questions like What does the term creepage distance mean? would be perfect , however the challenge that I am facing is finding questions that the answers are not easily found using Google.

Not sure this is what you are looking for; but the 110-230V unit is rated as a range, so the tolerance would be below 110 and above 230. The 110/230 V has two distinct rating ranges, so the tolerances would be above and below 110 AND above and below 230VAC. That's the first thing that pops into mind, anyway.

Re: [PSES] Interview Questions
Pre-screens that attempt to minimize consumption of a candidates' time is a
good thing.
What if the candidate logs in to answer one or two questions that evaluate
engineering judgment and/or problem solving? Perhaps you have to consider
that the knowledge of... stuff cannot be used as a first-pass screen.
This is best evaluated in-person.
I have had several interviews that focused on knowledge (facts) questions -
useless if it is something that can be looked up by a 2-second computer
search of the a standard or on-line data. The more obscure the knowledge
element, the more likely that it can be rapidly found with access to the
correct documents. With exception of one company, I am glad that they
('fact-based' interviewing companies) passed me up or I passed the company
up. A fact-based interview is shallow. Problem-solving interviews indicate
depth of thought by both the interviewer and the interviewee. Realize that
the superior candidates will also evaluate the interviewers.
The best compliance-related questions that have been posited to me follow:
1. After a few minutes discussing the circuit in a schematic - 'What is the
method that this converter uses to detect overload, how would Type-Test it,
and why?'
2. Is this code safety-critical? Why or why not?
3. Provided simple fly-back converter schematic and PCB layout and WV table
and calipers - 'Evaluate the spacings and provide general component
requirements for the circuit node outlined on the schematic'.
4. 'Do you prefer Agilent or R/S? Why?'

Hello All,
I have recently been tasked with writing a set of questions that job
candidates would need to answer at the same time they apply for a
position requiring knowledge of product safety evaluation, testing
and practices. These questions would serve as an automated pre

Re: [PSES] Interview Questions
I believe Nick may be fishing for the answer - a voltage selector switch. Back to the original question... Of course, an interview is much better for assessing this type of knowledge, but if you have to have questions on an application where candidates fill it out from home, you could ask questions based on personal experience, such as describe an experience you have had where you solved an issue with creepage distance and how you did it or something like that. People could always just lie and make something up, but it should be pretty easy to tell if someone has no idea what they're talking about. Much harder to Google this type of specific problem and solution, I would think.

Reminds me of back around 1994, when I interviewed at a now World-famous company for a position as an EMC engineer. I spent a very long day talking with 5 engineering groups, each of which had classic problems (shielding effectiveness, internal coupling, export compliance, CE RE). While I can't say I fixed every problem, I was able to set each group on a righteous path to their goal. And a few days later, their HR droid told me that, on reflection, they now thought they didn't really need a full-time in-house EMC guy. So that's how they were so profitable! The best compliance-related questions that have been posited to me follow: 4. 'Do you prefer Agilent or R/S? Why?' Hey, don't diss the Anritsu Thurlby guys!
