Smaller sizes, or slightly larger sizes, can be accommodated, but this equipment does not readily accept actual parts.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Standards can be obtained from appropriate standard authorities. 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.
Microprocessors monitor and precisely control the radiation applied to the test samples. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Therefore, all references to the use of this practice must be accompanied by a report prepared in accordance with Section r4459 that describes the specific operating conditions used. 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.
Xenon-Arc Accelerated Exposure
However, performance comparisons under the controlled conditions of 4d459 weathering can be compared to documented performance of materials and coatings that have experienced extended periods of end use 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. Assurance 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.
Assurance Testing Inspection Certification. Significant factors include regulation of line voltage, temperature and humidity control, and condition d44459 age of the lamps and filters.
A Weather-Ometer uses a xenon arc light source to provide a radiation spectrum that simulates natural sunlight. Historical Version s – view previous versions of standard. Need help or have a question?
Note 1 — There is no known ISO equivalent to this practice. Standard specimens are 69mm x mm. Formally confirming that your products and services meet all trusted external and internal standards. 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.

Xenon-Arc Accelerated Exposure
Validating the specifications, value and safety of your raw materials, products and assets. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Note 3 — Additional information on sources of variability and on strategies for xstm variability in the design, execution and data analysis of laboratory accelerated exposure tests is found in Guide G It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.
Various cycles are defined by the appropriate specifications depending upon the intended end use application. Moisture is provided by a humidifier and direct spray, and temperature is controlled by heaters. No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration.
Often several exposure times such as, and hours also will be compared asm each other. Send us a request Need help or have a question? This practice uses exposure in a xenon-arc device equipped with window glass filters and operated in accordance with Practices G and G
