Micom Laboratories is proud to announce that it now offers the ASTM D2126 test as part of its heat aging testing services. This test protocol attempts to characterize the effect of several temperatures and humidity on rigid cellular plastics through the use of a thermal and humidity cycling test . Indeed, this method relies on the physical measurements of the sample before and after the exposure in order to assess the stability of the container.
ASTM D2126 test
The goal of theASTM D2126 standard is to characterize the behavior of rigid cellular plastics towards a particular temperature and relative humidity. Indeed, this purpose is based on the principle that the properties and the stability of a polymer are subjected to the conditions they are exposed to. Therefore, this method provides some insights on the evolution of the attributes of the specimen through the use of a thermal and humidity test. The latter consists of exposing the sample to a temperature and a relative humidity that is similar to the intended ones for a specific time frame in order to assess the changes of the attributes of the plastic over time. As a matter of fact, the ASTM D2126 relies on the evaluation of the changes in dimensions and mass of the sample in order to characterize the effect of humidity and temperature towards the behavior of rigid cellular plastics. Also, the results obtained can serve to compare the performance of a material in a specific situation, to assess the relative performance of various cellular plastics or to define an acceptance criterion for a material. However, they cannot avail to predict the performance of the specimen nor be used in engineering calculations. Lastly, the purpose of this standard is similar to the goal of water resistance tests, but the means to achieve it is different.
Micom offers polymer testing services for a wide selection of material and products. For more information about the ASTM D2126 test, we invite you to contact our material testing laboratory today. It will be our pleasure to answer your questions about either of those tests.
