| Abstract: | The use of a polysulphone film as a physical standard for measuring light dosage in accelerated weathering tests is described. Tables are given of equivalent dose at 305 nm and correction factors for temperature of exposure. Examples of application are outlined showing effect of lamp and filter age on UV intensity and comparison of different light sources. |
