I was involved in something similar a few years ago, and purchased SAEJ2527
"Performance Based Standard for Accelerated Exposure of Automotive Exterior
Materials Using A Controlled Irradiance Xenon-Arc Apparatus".
It contains a few hints for testing, but is not very informative. I eventually
found a test lab who was knowledgeable, and relied on their experience to get
us through. We rarely have to perform this type of testing.
I'd be glad to discuss off-line.

Subject: [PSES] UV aging
Anybody know anything about UV aging for paints? I've looked over a couple of
standards and see at least one that purports 1,000 hours of test time under
Xenon lamps (I believe) is roughly 1 year in the Florida sun, but more
specifically I'm looking at the damage curve or something similar - if it
exists. Is most of the damage done in the first few days and then it goes
asymptotic like a capacitor discharge curve, or linear etc.
The main trouble with standards is that you have to buy them before you know
what's in them so I'm trying to zoom in a little before paying out the cash.
Standard scopes sometimes give a good idea what to expect some do not.
I know this isn't a EMC kind of thing - but we work around and with a lot of
different equipment and equipment requirements so I thought I would take a
chance here.
Thank you
