ASTM G151 Standard Guide for Exposing Nonmetallic Materials in Accelerated Test Devices that use Laboratory Light Sources

Scope:

The standard practice of ASTM G151 describes the general procedure for testing conditions to observe nonmetallic material properties tested by accelerated devices that use laboratory light sources. A material’s relative performance can be compared from the results conducted in the accelerated exposure test in accordance with this standard method.

Test Procedure:

In ASTM G151, the specimens are tested based on specific conditions and procedures for the exposure test depending on the type of device used and the material being tested. A controlled environment for test conditions such as light source, temperature, humidity, and wetting should be measured and considered for the test. Properties of the specimens before and after accelerated exposure tests should be observed.

Test Specimen:

As described in ASTM G151, the specimen dimensions should be as specified in the appropriate test method.

Conclusion:  

The standard practice ASTM G151 describes the exposure of nonmetallic materials in accelerated test devices that use laboratory light sources under specified test conditions.
