From: McInturff, Gary [mailto:gary.mcintu...@esterline.com] Sent: Monday, April 23, 2012 11:37 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] Safety cost and ESD Given the implementation differences between US/Canada(?) and EU on the medical 60601-1 standards. EU the June, US June 2013. How are folks handling new products being introduced now or in the very near future? Just got a quote back and the US certifier wants to charge me twice once for the 2nd edition and then to transition to the 3rd edition. I anyone else running aground on this. Seems like this should be happening on both sides of the pond - since a CB report to 3rd edition would run into the second edition enforcement in the US (and maybe Canada - I don't know their implementation date). To be fair - I get good service once I get past the sticker shock and don't have any complaints from that standpoint. In fact I enjoy the engineering staff I work with. Different question about ESD. I have a component we tested on the normal 55024 directed ESD table for a table top mounted device. Worked fine, problem is that the customer places this on a large metallic roll around pedestal on rubber wheels. When they send it to a lab and test it this way there is a problem. I don't have the pedestal so I'm trying to simulate with my table and removing the 1 mohm bleeder resistor. Between discharges to the table, I ground a braided strap attached to the table top to my reference plane below. I get very similar results then. What should the braid really look like - should it just be a short, should it have some bleed resistance in it. I chose none since the discharge is going to be people touching the pedestal or other furniture that is grounded. What does the standard say about the VCP and HCP?
