Here is a quick run-down on the types of bulbs used in UV, Accelerated weathering tests.
There are many different spectral irradiances of UV bulbs. Generally speaking:
500 hours under UV-B bulbs = 1 year of South Florida exposure
1000 hours under UV-A bulbs = 1 year South Florida exposure
1000 hours under Xenon Arc = 1 year South Florida exposure
There are additional UV exposure categories for an Arizona climate. (Dry, more intense UV & heat ) UV-A Bulbs:
Most accelerated weathering test chambers are designed to test a sample or “coupon” of a product – meaning a sample of the paint, coating or portion of the product that will be exposed to UV, heat/humidity. But if you want the entire product to be exposed Cascade TEK's MacGyver-like Test Technicians have modified our accelerated weathering test chambers to accommodate products much larger than just a sample or coupon size.
If your plastic, non-metal parts will face exposure to UV, light, rain, dew – and you need an established, respected industry standard to base product weathering testing on – consider these popular go-to test standards:
