The influence of chemicals on plastic packaging for dangerous goods has been examined, theoretically and experimentally, for the damage mechanisms of environmental stress cracking, swelling and oxidation. The results give an indication of the relevance of laboratory test methods for analyzing chemical degradation. Findings include that un-notched specimens can be used, that tensile testing is decisive only for the swelling phenomenon, while the tensile impact test is preferable for demonstration oxidative degradation. |
