Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Accelerated weathering provides exposed samples for comparison to unexposed control samples. Accelerated weathering simulates the damaging effects of long term outdoor exposure of materials and coatings by exposing aetm samples to varying conditions of the most aggressive components of weathering – light, moisture, and heat. Assurance Testing Inspection Certification.
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. Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice.
Inspection Validating the specifications, value and safety of your raw materials, products wstm assets.
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.
A Weather-Ometer uses a xenon arc light source to provide a radiation spectrum that simulates natural sunlight. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.

Certification Formally confirming that your products and services meet all trusted external and internal standards. Often several exposure times such as, and hours also will be compared to each other.
Historical Version s – view previous versions of standard. Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions. Formally confirming that your products and services meet all trusted external and internal standards.
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. 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. However, performance ashm 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.
Whether your business is local ast global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. Note 3 — Additional information on sources of variability and on strategies for addressing variability in the design, execution and data analysis of 4d459 accelerated exposure tests is found in Guide G Significant factors include regulation of line voltage, temperature and humidity control, and condition and age of the lamps and filters.
Various cycles are defined by the appropriate specifications depending upon the intended end use application. Smaller sizes, or slightly larger sizes, can be accommodated, but this equipment does not readily accept actual parts. Standard specimens are 69mm x mm. 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.
Auditing Consulting 4d459 Training. Need help or have a question? Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Up to 60 test samples are mounted in zstm Xenon Arc and subjected to a cycle of exposure asym specified combinations of light, humidity, temperature and water spray.
