- Scope
- This standard specifies the accelerated outdoor exposure test method for non-metallic materials using accelerated outdoor exposure test equipment composed of Fresnel (Fresnel) reflection system, and gives the equipment used (see Figure 1 and Figure 2) and equipment guidelines for use. This standard also specifies the equipment and methods that can be used to determine the relative durability of materials exposed to sunlight, heat and humidity, provided that the mechanism of physical and/or chemical changes occurring during the test is assumed to be decisive for the accelerated aging rate of the material Not much different. At the same time, it stipulates a unified sample installation method and maintenance procedures during the test process, and also provides maintenance procedures for equipment and reflection systems. This standard applies to specimens meeting the dimensional requirements of 8.2 and 8.3. This standard does not give the most suitable test conditions for specific materials, but is limited to measurement methods and process control. The preparation of samples for specific materials, test conditions and result evaluation can refer to existing standards and specifications.
