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 [email protected] http://www.linkedin.com/in/dougp01 - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
