Significant factors include regulation of line voltage, temperature and humidity control, and condition and age of the lamps and filters. Note 1 — There is no known ISO equivalent to this practice. Link to Active This link will always route to the current Active version of the standard.
Accelerated weathering provides exposed samples for comparison to unexposed control samples. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Moisture is provided by a humidifier and direct spray, and temperature is controlled by heaters.
Polystyrene Lightfastness Standards are included among the test samples to monitor and verify the performance of the equipment. Need help or have a question? However, performance comparisons under the controlled conditions of accelerated weathering can be compared to documented performance of materials and coatings that have experienced extended periods of end use exposure.
Standard specimens are 69mm x mm.
Various cycles are defined by the appropriate specifications depending upon the intended end use application. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
Smaller sizes, or slightly larger sizes, can be accommodated, but this equipment does not readily accept actual parts. Therefore, all references to the use of this practice must be accompanied by a report prepared in accordance with Section 9 that describes the specific operating conditions used.

Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions. Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice. Certification Formally confirming that your products and services meet all trusted external and internal standards.
Note 3 — Additional information on sources of variability and on strategies for addressing variability in the design, execution and data analysis of laboratory accelerated exposure tests is found in Guide G Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. This practice uses exposure in a xenon-arc device equipped with window glass filters and operated in accordance with Practices Astn and G A Weather-Ometer uses a xenon arc light source to provide a radiation spectrum that simulates natural sunlight. Validating the specifications, value qstm safety of your raw materials, products and assets. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.
Xenon-Arc Accelerated Exposure
Up to 60 test samples are adtm in the Xenon Arc and subjected to a cycle of exposure to specified combinations of light, humidity, temperature and water spray. Accelerated weathering simulates the damaging effects of long term outdoor exposure of materials and coatings by exposing test samples to varying conditions of the most aggressive components of weathering asstm light, moisture, and heat.
Assurance Testing Inspection Certification. Often several exposure times such as, and hours also will be compared to each other. Microprocessors monitor and precisely control the radiation applied to the test samples.
