This unexposed surface must not be used as part of the test area.

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. Assurance Testing Inspection Certification. This practice also covers the preparation of test specimens, the test conditions best suited aetm plastics, and the evaluation of test results. Hemispherical on 37 Degree Tilted Surface 2.

If four specimens are stacked vertically, then the specimens should be repositioned vertically three times during the test. Periods of Exposure and Evaluation of Test Results 8. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Validating the specifications, value and safety of your raw materials, products and assets. Instrumental measurements are recommended whenever possible.

Last previous edition approved in as D – Link to Active This link will always route to the current Active version of the astmm. The exposure used in this practice is not intended to simulate the deterioration caused by localized weather phenomena, such as, atmospheric pollution, biological attack, and saltwater exposure.


Therefore, no reference d439 the use of this practice should be made unless accompanied by a report prepared in accordance with Section 8 that describes the specic operating conditions used. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.

Accelerated Weathering (QUV) ASTM G154, ASTM D4329, ASTM D4587, ISO 4892

Do not xstm arbitrary acceleration factors relating time in an exposure conducted in accordance with this practice and time in an outdoor environment because they can give erroneous information. Inspection Validating the specifications, value and safety of your raw materials, products and assets.

Precision and Bias Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Follow the purity requirements in Practice G for water sprayed on specimen surfaces.

When specimens are removed from the exposure apparatus for 24 h or more and then returned for additional exposure, report the elapsed time as noted in accordance with Section 9. All specimens shall be exposed simultaneously in the same device. Originally approved in Need help or have a question?

NOTE d4392 some materials, changes may continue after the specimen has been removed from the exposure apparatus.

All concerned parties must agree on the specic control material used. Accelerated weathering provides exposed samples for comparison to unexposed control samples. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Parts may be accommodated depending on size.

It is recommended that deionized water be used for water used to produce condensation. Note 2 — 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 Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice. A asgm epsilon e indicates an editorial change since the last revision or reapproval.

NOTE 6—An example of a statistical analysis using multiple-laboratory and exterior exposures to calculate aatm acceleration factor is described by Simms. Typically, flat plaques or disks are used for accelerated weathering studies.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Expose replicates of the test specimen and the control specimen so that aastm signicant performance differences can be determined NOTE 8—Fischer illustrates use of rank comparison between test and control materials in specications.
