Standards can be obtained from appropriate standard authorities. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results. Link to Active This link will always route to the current Active version of the standard.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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 Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Significant factors include regulation of line voltage, temperature and humidity xstm, and condition and age of the lamps and filters.
Certification Formally confirming that your products and services meet all trusted external and internal standards. Microprocessors monitor and precisely control the radiation applied to the test samples.
Formally confirming that your products and services meet all trusted external and internal standards. Note 1 — There is no known ISO equivalent to this practice. Accelerated weathering simulates d44559 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.
Historical Version s – view previous versions of standard. 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.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. However, performance comparisons under the controlled conditions of accelerated weathering can s4459 compared to documented performance of materials and coatings that have experienced extended periods of end use exposure. Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions. Often several exposure times such as atm,and hours ast, will be compared to each other.
Auditing Consulting Sourcing Training. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Xenon-Arc Accelerated Exposure
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.

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. Standard specimens are 69mm x mm. This practice uses exposure in a xenon-arc device equipped with window glass filters and operated in accordance with Practices G and G Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
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.
Smaller sizes, or slightly larger sizes, can be accommodated, but this equipment does not readily accept actual parts. No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration.
