This practice also covers the preparation of test specimens, the test conditions best suited for plastics, and the evaluation of test results.
ASTM D4329
Operate the device continuously. Last previous edition approved in as D – No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration. D432 the specifications, value and safety of your raw materials, products and assets. Calculate retention of characteristic property in d439 with Practice D when it is reported.
Do not use 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.
Do not place the apparatus near a heat source such as an oven. 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.

Enabling you atm identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Precision and Bias This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.
Warning— Variation in results may be expected when operating conditions are varied within the accepted limits of this practice. Originally approved d43229 Accelerated weathering provides exposed samples for comparison to unexposed control samples.
Current edition approved July 15, Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice.
Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice. Conduct these round robins in accordance with Practice E or Practice D and include a statistically representative sample of all laboratories or organizations who would normally conduct the exposure and property measurement. 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.
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. Send us a request Wilton UK: When a single exposure period is used, select a time or radiant exposure that will produce the largest performance differences between the test materials or between the test material and the control material.

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 Assurance Testing Inspection Certification. Instrumental measurements are recommended whenever possible. It is recommended that deionized water be used for water used to produce condensation. Unless supplied with a specic backing as an integral part of the test, specimens shall be mounted so that only the minimum specimen area required for support by the holder shall be covered.
Therefore, no reference to the use of this practice should be made unless accompanied by a report prepared in accordance with Section 8 that describes the specific operating conditions used. Signicance and Use 4.
Signicant factors include regulation d43229 line voltage, temperature of the room in which the device operates, temperature control, and condition and age of the lamp. 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.
ASTM D – 05 Standard Practice for Fluorescent UV Exposure of Plastics
This method is preferred over evaluating materials after an arbitrary exposure time or radiant exposure. Measurements visual or astn should be made within a standardized time period or as agreed upon between the interested parties. Significant factors include regulation of line voltage, temperature of the room in which the device operates, temperature control, and condition and age of the lamp. Need help or have a question?
