The practice defined in the ASTM G155 standard developed by the American Society for Testing and Materials (ASTM) is limited to the basic principles and procedures for operating a xenon arc lamp and water apparatus and does not yield a specific result by itself. This standard is intended for use in conjunction with an application or method that defines specific exposure conditions for an application, along with a tool for evaluating changes in material properties.
The standard, whose full name is “ASTM G155-21 Standard Practice for Operating Xenon Arc Lamp Apparatus for Exposure of Materials, ” aims to reproduce the wear effects that occur when materials are exposed to sunlight (directly or through window glass) and moisture in the form of humidity, rain, or dew in real-world use. This practice is limited to procedures for obtaining, measuring, and controlling exposure conditions. A number of exposure procedures are included in the standard appendix. However, this practice does not specify the most appropriate exposure conditions for the material to be tested.
The ASTM G151 standard describes the general procedures and performance requirements to be used when exposing materials in an apparatus using laboratory light sources.
Test samples are exposed to light from an optically filtered xenon arc lamp under controlled environmental conditions. Different types of optical filters are described, along with xenon arc light sources. Sample preparation and evaluation of results are covered in ASTM methods or specifications for specific materials. General guidance is given in the ASTM G151 standard. General information on methods for detecting change in properties after exposure and reporting these results is described in ASTM D5870. This application is not designed for corrosion testing of bare metals.
Xenon arc testing supports property changes of materials, including the effects of sunlight, humidity, and heat, by simulating ultraviolet and visible solar radiation through a meteorology meter.
Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, is the standard for operating the closed carbon arc light apparatus for the exposure of non-metallic materials, within the scope of the ASTM G155-21 standard. It also provides testing services.
