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 Note 1 — There is no known ISO equivalent to this practice. Standards can be obtained from appropriate standard authorities. This practice uses exposure in a xenon-arc device equipped with window glass filters and aetm in accordance with Practices G and G Certification Formally confirming that your products and services meet all trusted external and internal standards.

Formally confirming that your products and 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.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

A Weather-Ometer uses a xenon arc light source to provide a radiation spectrum that simulates natural sunlight. No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration. Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice. Assurance Testing Inspection Certification.

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.

Microprocessors monitor and precisely control the radiation applied to the test samples. Accelerated weathering provides exposed samples for comparison to unexposed control samples.

Xenon-Arc Accelerated Exposure

asmt Historical Version s – view previous versions of standard. 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. 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 adtm standards. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.

However, performance comparisons under atm controlled conditions of accelerated weathering can be compared aztm documented performance of materials and coatings that have experienced extended periods of end use exposure. Need help or have a question? 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. Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions.

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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are f4459 provided as part of the standard.

Standard specimens are 69mm x mm. Polystyrene Lightfastness Standards are included among the test samples to monitor and verify the performance of the equipment. 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.

Often several exposure times such as, and hours also will be compared to each other. Auditing Consulting Sourcing Training.
