The standard specifies a method for the accelerated outdoor efflorescence testing of Non-metallic materials using a Fresnel reflector. The standard accelerates the exposure of materials to the environment by concentrating natural sunlight to assess their durability in sunlight, heat and Humidity conditions. The standard describes in detail the use of the test setup, sample installation and maintenance procedures to ensure the conformity and Reliability of the test results. The method does not specify specific exposure conditions, but provides uniform operating steps for testing to reduce the effect of variables on the results. Suitable for situations where the durability of materials in an actual outdoor environment needs to be assessed.
