Expose replicates of the test specimen and the control 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. Validating the specifications, value and safety of your raw materials, axtm and assets. All concerned parties must agree on the control material used.
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 ast, in the case of revision, the year of last revision.
This practice also covers the preparation of test specimens, the test conditions best suited for plastics, and the evaluation of test results.

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.
Misleading results may be obtained by this method, since the masked portion of the specimen is still exposed to temperature and humidity cycles that in many cases will affect results.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Measure ambient temperature at a maximum distance of mm [6 in. Warning— Variation in results may be expected when operating conditions are varied within the accepted limits of this practice.

The acceleration factor is materialdependent and is only valid if it is based on aastm from a 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.
Assurance 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. 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.
Follow the purity requirements in Adtm G for water sprayed on specimen surfaces.
No direct correlation can be made between accelerated weathering duration ashm actual outdoor exposure duration. Current edition approved July 15, It is recommended that deionized water be used for water used to produce condensation. All specimens shall be exposed simultaneously in the same device. For measurements 8 Fischer, R.
