I must admit than EN60960 is a new one on me, but first some EEC regulatory
background for our non-EEC colleagues (anyone in Europe can now book a 10
min. snooze...):
The EEC CE-mark requires that a product compiles with *all* relevant
directives, one of which is usually the Low Voltage Directive (LVD), known
to it's friends as 73/23/EEC. One route to compliance is testing to
relevant standards. Our products come under the classification of IT
Equipment and the appropriate electrical safety standard is EN 60950. The
latest version is EN60950:2000, which became current on 2001/01/01 - however
the date of withdrawal (DOW) for earlier versions/other conflicting
standards (e.g. it's predecessor EN60950:1992) is 2005/01/01 so these
standards can be used for product on sale before that date. Any information
on EN60960 would be gratefully received.
(Note 1: the 'DIN' prefix Michael uses is the result of integrating
Europe-wide standards into national formats, for example if I were to order
EN60950 from British Standards (BSI) it would be BS EN60950 whereas in
Germany it would be DIN EN60950).
The format of the CE mark is covered by a separate directive, and as far as
I am aware this hasn't changed in the last couple of years. Again, any
information to the contrary would be most useful! The original CE-mark
label had to include the year of application, to give some idea of which
standards may have been applied as new ones & revisions are ongoing, but
this was removed at the last update (!).
The EEC regulations apply equally across all the countries in the EEC.
** time to wake up :-)
Section 2.10 of EN60950:2000 has tables for clearances etc., but at first
glance it's not too clear whether this refers to actual circuit boards as
well as e.g. mains-to-chassis gaps (we've always managed to keep mains off
our boards, so I haven't needed to go too deeply into this aspect of it
yet).
Does anyone have more info on the relevant ETSI specification?
I hope I haven't bored people too much. Aren't standards fun.. 8-)
