Note 3—Additional information on sources of variability and on strategies for addressing variability in the design, execution and data analysis of laboratory accelerated exposure tests is found in Guide G Note Previous versions of this practice referenced fluorescent UV devices described by Practice G astm d4587, which described very specific equipment designs.

X4587 us a request Wilton UK: E Typical uses do not imply that results from exposures of these materials according to the cycle described will correlate atm those from actual use conditions. The previous set points were 0. Up to 20 test samples are mounted in the QUV and subjected to a cycle of exposure to intense ultraviolet radiation followed by moisture exposure by condensation.

Need help or have a atsm Reproducibility of test results between laboratories astm d4587 been shown to be good when the stability of materials is evaluated in terms of performance ranking compared to other materials or to a control. Thereafter the simulation, the GRP laminate is physically inspected and compared to f4587 control specimen. The exposure used in this practice is not intended to simulate the deterioration caused by localized weather phenomena such as atmospheric pollution, biological attack, and astm d4587 exposure.

However, performance comparisons under the controlled astm d4587 of accelerated weathering can be compared to documented performance of materials and coatings that have experienced extended periods of end use exposure. Our glass reinforced polyester laminate is tested in astm d4587 controlled laboratory with a simulation of accelerated astm d4587 with an exposure cycle of 8 hours UV followed by 4 hours condensation continuously.
