Inspection Validating the specifications, value and safety of your raw materials, products and assets. 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. asmt
Please first log in with a verified email before subscribing to alerts. Typically, flat plaques or disks are used for accelerated weathering studies. 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.
ASTM D – 05 Standard Practice for Fluorescent UV Exposure of Plastics
The standard sample holders can hold one sample 3 x 12 inches 75 x mm or two samples 3 x 6 inches 75 x mm. Add to Alert PDF. As the voice of the U. NOTE 4—This is especially important when mechanical properties are being investigated. All concerned parties must agree on the control material used.
ASTM D-4329-05 QUV
x4329-05 You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Obtain mutual agreement between all concerned parties for the specic exposure cycle used.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. It is recommended that deionized water be used for water used to produce condensation.
Send us a request Wilton UK: Assurance Testing Inspection Certification. This unexposed surface must not be used as part of the test area. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
This practice also covers the preparation of test specimens, the test conditions best suited for plastics, and the evaluation of test results. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Hemispherical on 37 Degree Tilted Surface 2.
Accelerated Weathering (QUV) ASTM G154, ASTM D4329, ASTM D4587, ISO 4892
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. 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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. This practice is intended to induce property changes associated with end-use conditions, including the effects of sunlight, moisture, and heat. NOTE 7—For some materials, changes may continue after the specimen has been removed from the exposure apparatus.
ASTM D – Standard Practice for Fluorescent UV Exposure of Plastics
Originally approved in 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 d43229-05 original adoption or, in the case of revision, the year of last revision. Do not place the apparatus near a heat source such as an oven.
The acceleration factor is materialdependent and is only valid if it is based on data from astk sufficient number of separate exterior and laboratoryaccelerated exposures so that results used to relate times to failure in each exposure can be analyzed using statistical methods.
Current edition approved July 15, 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. 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.
Periods of Exposure and Evaluation of Test Results 8. 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.
