ASTM G 155 - 05a Standard Practice for Operating Xenon Arc Light Apparatus for Exposure of Non-Metallic Materials

American Society for Testing and Materials (ASTM). Current edition approved Oct. 1, 2005. Published November 2005. Originally approved in 1997. Last previous edition approved in 2005 as G 155 – 05. 11 p. This practice covers the basic principles and operating procedures for using xenon arc light and water apparatus intended to reproduce the weathering effects that occur when materials are exposed to sunlight (either direct or through window glass) and moisture as rain or dew in actual use. This practice is limited to the procedures for obtaining, measuring, and controlling conditions of exposure. A number of exposure procedures are listed in an appendix; however, this practice does not specify the exposure conditions best suited for the material to be tested.
