Brian - thanks but have clarified it - IEC 61058 requires all parts to be V-2 or HB or better dependent on which part of the switch is considered - however EN 60065:2002 (and the obs 1998) imposes the additional need for V-0 throughout.............
Thanks - Chris From: [email protected] [mailto:[email protected]] On Behalf Of Brian O'Connell Sent: 11 April 2008 16:35 To: [email protected] Subject: RE: EN 60065:2002 & mains switches I just happened to be looking at UL61058-1 - as I have no life at all - (UL says that it is based on IEC61058-1, Ed 3.1). Clause 21.1 (res to heat and fire) references Annex E for the ball pressure test, and Annex C for the glow-wire test. While I would not consider use of a switch that is not 61058-certified, it would seem that the tests referenced in 61058-1 are needed only if you are evaluating the switch as a separate item. And if you are evaluating it as a separate component, you need to use the most stringent level (3). The flammability (glow-wire and ball-pressure) tests are applied to current-carrying parts and parts that used for protection against shock. The test temperature level 3 = 850 degC. 61058-1 also says "Where an appliance standard gives no indication of the level, reference can be made to IEC 60335-1 for guidance." Also, 61058-1 has other electrical and mechanical and EMC requirements. luck, Brian > -----Original Message----- > From: [email protected] [mailto:[email protected]]On Behalf Of James, > Chris > Sent: Friday, April 11, 2008 4:56 AM > To: [email protected] > Subject: EN 60065:2002 & mains switches > > Does Clause 14.6.1 (a) "translate" to meaning mains switches > must exceed > the flammability specification of IEC 61058-1? > > 14.6.1 (a) requires them to meet 61058-1 but then says ............. > Moreover, MAINS SWITCHES shall comply with the flammability > category V-0 > or according to G.1.1 of Annex G. > > I don't posses 61058 so don't know what that calls > for............... > > Chris - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
