CHICAGO – Atlas Material Testing Technology announced that its Ci Series Weather-Ometers meet the recently published test method ASTM D 7869-13, Standard Practice for Xenon Arc Exposure Test with Enhanced Light and Water Exposure for Transportation Coatings.
For over 20 years, SAE J1960 (and the performance-based equivalent, SAE J2527) has been the most popular test method used for testing automotive exterior materials. First developed by General Motors in the mid-1980's, the test method was soon adopted by several other automotive OEMs, especially in the United States and Japan. Despite the popularity of this method, it was deficient in terms of the quality of the spectral power distribution (SPD) for the light source, moisture delivery, and irradiance level to provide meaningful acceleration and correlation.
