It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results. Up to 60 test samples are mounted in the Xenon Arc and subjected to a cycle of wstm to xstm combinations of light, humidity, temperature and water spray.

Xenon-Arc Accelerated Exposure
Validating the specifications, value and safety of your raw materials, products and assets. Certification Formally confirming that your products and services meet all trusted external and internal standards.
Various cycles are defined by the appropriate specifications depending upon the intended end use application.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions. Inspection E4459 the specifications, value and safety of your raw materials, products and assets.
No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. However, performance comparisons under the controlled conditions of accelerated weathering can be compared to documented performance of materials and coatings that have experienced asmt periods of end use exposure. Moisture is provided by a humidifier and direct spray, and temperature is controlled by heaters.
Often several exposure times such as, and hours also will be compared to each other.
These cycles would aastm continued for extended periods of time – up to thousands of hours – simulating even longer periods of time in the real world. Assurance Testing Inspection Certification. Note 3 — Additional information on sources of variability and astn strategies for addressing variability in the design, execution and data analysis of laboratory accelerated exposure tests is found in Guide G Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

Xenon-Arc Accelerated Exposure
A Weather-Ometer uses a xenon arc light source to provide a radiation spectrum that simulates natural sunlight. Significant factors include regulation of line voltage, temperature and humidity control, and condition and age of the lamps and filters.
Auditing Consulting Sourcing Training. Note 1 — There is no known ISO equivalent to this practice. This practice uses exposure in a xenon-arc device equipped with window glass filters and operated in accordance with Practices Sstm and G 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.
Standards can be obtained from appropriate standard authorities. Formally confirming that your products and services meet all awtm 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.
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. 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. Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice.
