ASTM D2126-09

Standard Test Method for Response of Rigid Cellular Plastics to Thermal and Humid Aging

SIGNIFICANCE AND USE
Because of the wide variety of potential uses of rigid cellular plastics, artificial exposure to estimate the effective behavior of these materials must be based, to a great extent, on the intended application. Toward this end, this test method is intended to recommend a variety of conditions from which one or more of the desired exposure conditions can be selected. (Note 3)
The conditions recommended in this test method have been widely used in artificially exposing rigid cellular plastics and in determining the effects of various temperatures and humidities on these materials. Final test measurements are determined after the specimens return to room temperature. Where specified, the specimens will be tested at the exposure condition, but must be reported as such.
Dimensional changes measured by this test method can be used to compare the performance of materials in a particular environment, to assess the relative stability of two or more cellular plastics, or to specify an acceptance criterion for a particular material. The results of this test method are not suitable for predicting end-use product performance or characteristics, nor are they adequate for engineering or design calculations.
Note 3—Where thermal shock is known or suspected to occur due to rapid heating to (or cooling from) a particular temperature, guidance on the permissible heating or cooling rates, or both, shall be obtained from the manufacturer of the material concerned.
Note 4—The dimensional change of a specimen can vary depending upon the age of the sample or the length of time between specimen preparation and the beginning of the test, or both.
Before proceeding with this test method, reference shall be made to the specification of the material being tested. Any test specimen preparation, conditioning, dimensions, or testing parameters covered in the materials specification, or combination thereof, shall take precedence over those mentioned in this test method. If there are no ...
