Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice.
Xenon-Arc Accelerated Exposure
Formally confirming that your products and services meet all trusted external and internal standards. Send us a request Wilton UK: Assurance 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. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
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 awtm Practices G and G Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Validating the specifications, value and safety of your raw materials, products and assets.
Standards can be obtained from appropriate standard authorities.
Certification Formally confirming that your products and services meet all trusted external and internal standards. 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.
Xenon-Arc Accelerated Exposure
Significant factors include regulation of line voltage, temperature and humidity control, and condition and age of the lamps and filters. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. 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.
Auditing Consulting Sourcing Training. Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions. Historical Version s – view previous versions of standard. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Often several exposure times such as, and hours also will be compared to each other. Accelerated weathering provides exposed samples for comparison to unexposed 4d459 samples.
Link to Active This link will always c4459 to the current Active version of the standard. Need help or have a question? It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine satm applicability of regulatory limitations prior to use. Smaller sizes, or slightly larger s4459, can be accommodated, but this equipment does not readily accept actual parts.
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 the performance of the equipment. Assurance Testing Inspection Certification. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Send us a request Need help or have a question? Standard specimens are 69mm x mm. 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.
Note 1 — There is no known ISO equivalent to this practice. 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.
Microprocessors monitor and precisely control the radiation applied to the test samples. 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. No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration. Various cycles are defined by the appropriate specifications depending upon the intended end use application.
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. A Weather-Ometer uses a xenon arc light source to provide a radiation dd4459 that simulates natural sunlight.
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
