Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice.

asfm Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results. Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions.

Moisture is provided by a humidifier and direct spray, and temperature is controlled by heaters. Validating the specifications, value and safety of your raw materials, products and assets. Up to 60 test samples xstm mounted in the Xenon Arc and subjected to a cycle of exposure to specified combinations of light, humidity, temperature and water spray.

Xenon-Arc Accelerated Exposure

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Standard specimens are 69mm x mm. No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration.

Inspection Validating the specifications, value and safety of your raw materials, products and assets. This practice uses exposure in a xenon-arc device equipped with window glass filters and operated in accordance with Practices G and G Often several exposure times such as, and hours also will be compared to each other. 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 It is the responsibility of the user of this d459 to establish appropriate safety and health astj and determine the applicability of regulatory limitations prior to use.

Significant factors include regulation of line voltage, temperature d44599 humidity control, and condition and age of the lamps and filters.

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. Assurance Testing Inspection Certification.

Xenon-Arc Accelerated Exposure

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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Accelerated weathering provides exposed samples for comparison to unexposed control samples.

Formally confirming that your products and services meet all trusted external and internal x4459. A Weather-Ometer uses a xenon arc light source to provide a radiation spectrum that simulates natural sunlight.

Smaller sizes, or slightly larger sizes, can be accommodated, but this equipment does not readily accept actual parts. Testing 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. Various cycles are defined by the appropriate specifications depending upon the intended end use application. Global Reach Intertek is the industry leader with over wstm, people in 1, locations in over countries.

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