Looking at UL60950-1 2d ED, I note the existence of clause 2.7.4 [Number and location of protective devices], and do not find the void statement after 2.7.1.
The UL std states "NOTE In the member countries of CENELEC, the protective devices necessary to comply with the requirements of 5.3 must, with certain exceptions, be included as part of the equipment" after clause 2.7.1. The UL std is also derived from IEC60950-1 2d ED, so I am not know why this clause is missing. luck, Brian From: [email protected] [mailto:[email protected]]On Behalf Of Steve Richardson, Blackwood Labs Sent: Tuesday, October 16, 2007 2:36 AM To: [email protected] Subject: BS EN 60950-1:2006 clause 2.7 numbering Hello all, My copy of BS EN 60950-1:2006 has no clause 2.7.4 is this correct or an omission? I can't find any indication of what has happened to it. Also after clause 2.7.1 there is a statement detailing that 'This subclause has been declared void' Is this a clause numbering error which has been picked up for a future amendment?
