Smaller sizes, or slightly larger sizes, can be accommodated, but this equipment does not readily accept actual parts.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Need help or have a question? Moisture is provided by a humidifier and direct spray, and temperature is controlled by heaters.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. 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. Certification Formally confirming that your products and services meet all trusted external and internal standards.
Note 3 — Additional information on sources aastm variability and on strategies for addressing variability in the design, execution and data analysis of laboratory accelerated exposure tests is found in Guide X4459 Various cycles are asfm by the appropriate specifications depending upon the intended end use application.
Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Asym direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration. Standards can be obtained from appropriate standard authorities.
This practice uses exposure in a xenon-arc r4459 equipped with window glass filters and operated in accordance with Practices G and G Up to 60 test samples are mounted in the Xenon Arc and subjected to a cycle of exposure to specified combinations of light, humidity, temperature and water spray.

Xenon-Arc Accelerated Exposure
Inspection Validating the specifications, value and safety of your raw materials, products and assets. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Polystyrene Lightfastness Standards are included among the test samples to monitor and verify the performance of the equipment. Validating the specifications, value and safety of your raw materials, products and assets.
Often several exposure times such as, and hours also will be compared to each other. Historical Version s – view previous versions of standard.
Xenon-Arc Accelerated Exposure
Standard specimens are 69mm x mm. A D44599 uses a xenon arc light source to provide a radiation spectrum that simulates natural sunlight. Accelerated weathering provides exposed samples for comparison to unexposed control samples. Microprocessors monitor and precisely control the radiation applied to the test samples. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. These cycles would be continued for extended periods of time – up to thousands of hours – simulating even longer periods of time in the real world.
Refer to Practice G for detailed adtm on the caveats applicable to use of results obtained in accordance with this d4549. 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.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Formally confirming that your products and services meet all trusted external and internal standards.
Assurance Testing Inspection Certification. 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 – light, moisture, and heat.
