Expose replicates of the test specimen and the adtm specimen so that statistically signicant performance differences can be determined NOTE 8—Fischer illustrates use of rank comparison between test and control materials in specications.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. The standardized time period needs to consider conditioning prior to testing. This method is preferred over evaluating materials after an arbitrary exposure time or radiant exposure. Proceed to Checkout Continue Shopping.

This practice also covers the preparation of atsm specimens, the test conditions best suited for plastics, and the evaluation of test results.

Accelerated Weathering (QUV) ASTM G, ASTM D, ASTM D, ISO

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. D4329-0 factors include regulation of line voltage, temperature of the room in which the device operates, temperature control, and condition and age of the lamp.

ASTM D – 05 Standard Practice for Fluorescent UV Exposure of Plastics

Your comments will receive careful consideration at a meeting ast the responsible technical committee, which you may attend. 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.

You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Attach porous specimens to a solid backing such as aluminum that can act as a vapor barrier.

If four specimens are stacked vertically, then the specimens should be repositioned vertically three times during the test. Already Subscribed to this document.

Control of ambient temperature is particularly critical when one apparatus is stacked above another, because the heat generated from the lower unit can interfere with the operation of the units above.

As the voice of the U. D — 05 Standard Practice for Fluorescent UV Exposure of Plastics1 This standard is issued under the xed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. Last previous edition approved in as D – NOTE 6—An example of a statistical analysis using multiple-laboratory and exterior exposures to calculate an acceleration factor is described by Simms.


Calculate retention of characteristic property in accordance with Practice D when it is reported. NOTE 4—This is especially important when mechanical properties are being investigated. Assurance Testing Inspection Certification.

Your Alert Profile lists the documents that will be monitored. Standards can be obtained from appropriate standard authorities. Typically, flat plaques or disks are used for accelerated weathering studies. All specimens shall be exposed simultaneously in the same device. Signicance and Use 4.
