Standard Practice for Conditioning Plastics for Testing

Importancia y uso:

4.1 Conditioning of specimens is typically conducted: (1) for the purpose of bringing the material into equilibrium with normal or average room conditions, (2) simply to obtain reproducible results, regardless of previous history of exposure, or (3) to subject the material to abnormal conditions of temperature or humidity in order to predict its service behavior.

4.2 The conditioning procedures prescribed in this practice are designed to obtain reproducible results and have the potential to give physical values somewhat higher or somewhat lower than values under equilibrium at normal conditions, depending upon the particular material and test. Depending on the thickness, type of material and its previous history, it is possible that it would take 20 to 100 days or more to ensure substantial equilibrium under normal conditions of humidity and temperature. Consequently, conditioning for reproducibility must of necessity be used for general purchase specifications and product control tests.
