Developed by the Society of Automotive Engineers (SAE), the SAE J2527 standard describes operating procedures for a controlled radiation, xenon arc apparatus used for accelerated exposure of various exterior automotive materials.
Sample preparation, test times and performance evaluation procedures are included in the material specifications of different automotive manufacturers. Any deviations from this test method, such as filter combinations, must be agreed upon by the contracting parties.
This standard is a new performance-based aging testing method that will replace legacy hardware-based methods. This test method describes exposure conditions and control tolerances rather than identifying a particular hardware configuration.
While the automotive industry leads the world in many areas, it has lagged behind in adopting performance-based aging standards. Thereupon, in the late 1990s, three new accelerated aging standards were published by SAE to address the gap in accelerated aging test standards:
The biggest difference between the new performance-based aging standards and the old hardware-based standards is the removal of all manufacturer-specific references. Parts of test standards that refer to a manufacturer's trade names have been replaced with generic definitions. For example, the optical filters used in the test have been redefined. In older hardware-based testing standards, optical filters were referred to as quartz internal filter and type S borosilicate external filter. In the new performance-based test standards, trade names for optical filters have been removed and replaced with a definition of the required spectral power distribution.
The forward-looking policies of international standards bodies such as ISO, ASTM, and SAE are that all testing standards should be performance-based.
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 a performance-based standard for accelerated exposure of automotive exterior materials using controlled radiation xenon-arc apparatus within the scope of SAE J2527 standard. It also provides testing services.
