Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions. 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. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Inspection Validating the specifications, value and safety of your raw materials, products and assets.

Validating the specifications, value and safety of your raw materials, products and assets.

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.

Xenon-Arc Accelerated Exposure

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. Standards can be obtained from appropriate standard authorities. No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration. Enabling you to identify and mitigate the intrinsic aatm in your operations, supply chains and business processes.

Microprocessors d4459 and precisely control the radiation applied to the test samples. 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.

Xenon-Arc Accelerated Exposure

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Accelerated weathering simulates the damaging effects of long term outdoor exposure of materials aastm coatings by exposing test samples to varying conditions of the most aggressive components of weathering – light, moisture, and heat.

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 Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.

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. Smaller sizes, or slightly larger sizes, can be accommodated, but this equipment does not readily accept actual parts.

Certification Formally confirming that your products and services meet all trusted external and internal standards. 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.
