ASTM D7869 Standard Practice for Xenon Arc Exposure Testing with Enhanced Light and Water Exposure for Transport Coatings

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM D7869 testing. This standard specifies operating procedures for a controlled glow xenon arc light and water apparatus.

The procedure uses one or more lamps and optical filters to produce a glow similar to sunlight in the UV and visible range. It also simulates the water absorption and stress cycles that automotive exterior coatings experience under natural weather conditions.

This application has also been found to be applicable to coatings on other transportation vehicles such as airplanes, trucks and wagons.

This application uses a xenon arc light source with specified optical filters. Water is sprayed onto the samples during portions of several dark steps. The water application is such that the coatings absorb and remove a significant amount of water during testing. In addition, cycling between wet-dry and hot-cold will cause mechanical stresses in the materials.

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
