This standard is issued under the fixed designation D ; the number 1 This practice is under the jurisdiction of ASTM Committee D20 on. It is the responsibilty of the Lab Manager to verify this setup is acceptable for the particular application or test method. ***. Test Method: ASTM D Buy ASTM D PRACTICE FOR XENON-ARC EXPOSURE OF PLASTICS INTENDED FOR INDOOR APPLICATIONS from SAI.
Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice.
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. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Assurance Testing Inspection Certification. Send us a request Wilton UK: Standard specimens are 69mm x mm. A Weather-Ometer uses a xenon arc light source to provide d44559 radiation spectrum that simulates natural sunlight.
Often several exposure times such as, and hours also will be compared to each other. Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions. 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 Certification Formally confirming that your products d4495 services meet all trusted external and internal standards.
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. Microprocessors monitor and precisely control the radiation applied to the test samples.
This practice uses exposure in a asym device equipped with window glass filters and operated in accordance with Practices G and G Auditing Consulting Sourcing Training. Polystyrene Lightfastness Standards are included among the test samples to monitor and verify the performance of the equipment.
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.
It is recommended that at least three replicates of each material be exposed to aetm for statistical evaluation of results.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. Standards can be obtained from appropriate standard authorities. Smaller sizes, or slightly larger sizes, can be accommodated, but this equipment does not readily accept actual parts.
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 f4459. Various cycles are defined by the appropriate specifications depending upon the intended end use application.

Significant factors include regulation of line voltage, temperature and humidity control, and condition and age of the lamps and filters. Moisture is provided by a humidifier and direct spray, and temperature is controlled by heaters.
Therefore, all references to the use of this practice must be accompanied by a report prepared in accordance with Section 9 that describes asstm specific operating conditions used. Accelerated weathering provides exposed samples for comparison to unexposed control samples.

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. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration. Formally confirming that your products and services meet all trusted external and internal standards.
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.
