All, NOTE – Location Change For The April 26 NPSS Meeting
Location: BioDefense Corporation 128 Spring Street Lexington, MA 02062 Contact is Tony Nikolassy at (781) 861-8810 X222 There will be a Northeast Product Safety Society meeting on Wednesday, April 26th, at BioDefense Corporation at 128 Spring Street, Lexington, MA. A social hour with light refreshments will begin at 7:00 PM and the technical meeting will start at 7:30 PM. Moe Lamothe, President of Lamothe & Associates Inc., will present this month’s topic concerning spacings using 61010-1 as the base standard. The method is also applicable to 60950-1 and other IEC based standards. If you will be in the area, please feel free to join us as advanced notice or membership in NPSS or IEEE PSES is not required. Moe is currently President of M.A. Lamothe & Associates Inc. which provides companies with a professional, worldwide product safety approvals service. Moe received his BS in Mechanical Engineering from the University of Alberta and is a registered PE in Ontario, Canada. Prior to founding Lamothe & Associates in 1979, he was first a Design Engineer and later an Engineering Manager at various Canadian companies including Johnson & Johnson and Smith & Stone. Since 1988, Moe has been a member of the Technical Advisory Board of TUV Rheinland of North America, Inc. which oversees TUV's activities as an SCC accredited Testing and Certification Organization, as well as TUV's ISO 9000 / ISO 14000 registrar operations. He is the only Canadian member of this Advisory Board. Further information concerning Moe is available at http://lamothe-approvals.com/cvmoe.htm. The presentation will be fairly technical and will look at Spacings using 61010-1 as the base standard. 61010-1 approaches spacings via the ‘Block Diagram’ method which provides a very powerful visual analysis tool. Spacings (creepage and clearance) between various circuits will be considered along with how working voltage affects this spacing. The logical sequence of steps to get the proper results will be presented via the ‘Block Diagram’ method: 1. Identify circuits in the equipment (Block Diagram) 2. Identify all accessible parts (earthed and unearthed) 3. Draw block diagram with these circuits and accessible parts 4. Determine the required isolation type between each circuit and accessible part 5. Determine the working voltage for each required isolation 6. Determine the required clearance and creepage distance for each isolation point If you or anyone you know would like to give a product safety technical presentation, please contact Paul Smith, our meeting scheduler, by email at pauljsmi...@cs.com. A technical presentation should be 45 to 60 minutes in duration and be related to product safety. Although the presentation may reference your company and it’s services, the presentation must not be simply company advertising. We would also appreciate any slides or handout materials be made available for posting on the NPSS web site. Releasing presentation materials for posting is desired but not a requirement to make a presentation.
