A Weather-Ometer uses a xenon arc light source to provide a radiation spectrum that simulates natural sunlight.
Xenon-Arc Accelerated Exposure
Send us a request Wilton UK: However, performance comparisons under the controlled conditions of accelerated weathering can be compared to documented aastm of materials and coatings that have experienced extended periods of end use exposure.
Assurance Testing Inspection Certification. Moisture is provided by a humidifier and direct spray, and temperature is controlled by heaters. Certification Formally confirming that your products and services meet all trusted external and internal standards.
Validating the specifications, value and safety of your raw materials, products and assets. 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.
No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. Need help or have a question?
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 Asrm sizes, or slightly larger sizes, can be accommodated, but this equipment does not readily accept actual parts. Historical Version s – view previous versions of standard.
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 asmt. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice. Often several exposure times such as, and hours also will be compared to each other. 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.
It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results. Standard specimens are 69mm x mm. 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.
Microprocessors monitor and precisely control the radiation applied to the test samples. Standards can be obtained from appropriate standard authorities.
