Anyone with experience in applying any of the standards in the subject, I
would
appreciate your comments.
Product in question:
DC supplied Independant Electronic Ballast for Metal Halide lamp.
30V DC in, Max Power 250W. Max output 300V (Pulse voltage)
Ignitor fitted in remote lamphead.
Conformity to EN standards required for European sales. Also UL conformity
for future third party testing for USA sales.
Which standard do I apply?
EN60598-1 or EN60922, and which UL standard should I be looking at?
I have copies of 60598 and 60922 and my comments are below:
60922:1997
-----------
"Section 1.1 Scope and object:
The standard covers inductive ballasts for use on a.c. supplies up to
1000V..."
"
Parts of this standard can be applied, most ignored, and some leave me
in the dark.
60922 concentrates on mechanical and thermal properties of the ballast.
The ballast I am looking for a standard for is just a DC driven switch
mode power supply.
There are no big windings as in inductive ballasts
60598-1:2000 (supersedes 60598-1:1997 +A1:1998 + A12:1998 + A13:1999)
----------
Section 0.5.1
"Components, other than integral components, shall comply with the
requirements of the relevant IEC standard, if any."
Section 0.5.3
"Components for which no appropriate IEC standard exists shall satisfy
the relevant requirements of this luminaire standard as part of the
luminaire."
"Note - Examples of components are lampholders, switches, ballasts,
flexible cables and cords and plugs."
This is a whopper of a read, and also the standard applied by a
consultancy company when evaluating an A.C. version of this ballast.
I also came across IEC 60923:1996, Ballasts for discharge lamps
(excluding tubular fluorescent lamps)
I feel EN60598-1 is the correct standard. Does anyone agree?
Thanks in advance.
Enci.
