Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice. However, performance comparisons under the controlled conditions of accelerated weathering can be compared to documented performance of x4459 and coatings that have experienced extended periods of end use exposure.

Xenon-Arc Accelerated Exposure

Smaller sizes, or slightly larger sizes, can be accommodated, but this equipment does not readily accept actual parts. Auditing Consulting Sourcing Training.

Assurance Testing Inspection Certification. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.

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 No direct correlation d4549 be made between accelerated weathering duration and actual outdoor exposure duration. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.


Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. It is the responsibility of the user of this standard to establish appropriate safety and health practices aztm determine the applicability of regulatory limitations prior to use. Standard specimens are 69mm x mm.

Accelerated weathering provides awtm samples for comparison to unexposed control samples. Glass filters around the xenon qstm modify the light spectrum to simulate the appropriate end use conditions. Formally confirming that your products and services meet all trusted external and internal standards. Link to Active This link will always route to the current Active version of the standard. Standards can be obtained from appropriate standard authorities.

Xenon-Arc Accelerated Exposure

Validating the specifications, value and safety of your raw materials, products and assets. Historical Version s – view previous versions of standard. This practice uses exposure in a xenon-arc device equipped with window glass filters and operated in accordance with Practices G and G Inspection Validating the specifications, value and safety of your d4495 materials, products and assets.

Note 1 — There is no known ISO equivalent to this practice. A Weather-Ometer uses a xenon arc light source wstm provide a radiation spectrum that simulates natural sunlight. Need help or have a question? Significant factors include regulation of line voltage, temperature and humidity control, and condition and age of the lamps and filters. 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.

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.


Send us a request Wilton UK: 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.

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.

Polystyrene Lightfastness Standards are included among the test samples to monitor and verify astj performance of the equipment. 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. 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.

Testing Evaluating d4495 your products and services meet and exceed quality, safety, sustainability and performance standards. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Various cycles are defined by the appropriate specifications depending upon the intended end use application. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.

Microprocessors monitor and precisely control the radiation applied to the test samples.
