At least for UL60950 (3d ed) and Ul 3101-1/3111-1, the spacing tables are the same as EN60950:2k and EN 610101-1.
What UL standards have spacing requirements that are different than the EN std w/equivalent scope? I would really appreciate this info. thanks, Brian -----Original Message----- From: David Sproul [mailto:david.spr...@alexanderlynn.co.uk] Sent: Tuesday, October 08, 2002 8:51 AM To: richwo...@tycoint.com Cc: EMC-PSTC Subject: RE: Creepage Can anyone give a rational reason why UL ask for around twice the creepage distances for 120V that EN standards ask for 230V. I realise this is a bit vague, but I can dig out some examples if any needs to be convinced. I have been asked this by customers on a number of occasions, and have always meant to find out so I would no longer have to apologise for not knowing. ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
