T1 - Comparison of the notched impact strength at -30°C of polyethylene grades with the test performance behavior of packagings for the transport of dangerous goods N2 - The notched impact strength at -30 °C is one of the selected properties, together with the corresponding test method and tolerances, for a comparison of polyethylene grades of one design type in the procedural rule on suitability proof for alternative plastic resins used for packagings and intermediate bulk containers (IBCs) for the transport of dangerous goods. The marginal drop heights determined with the drop test at -18 °C after pre-storage of the test samples with 55 % nitric acid at 40 °C only partly related to the notched impact strength at -30 °C. The Charpy method is only suitable for classifying the grade in relation to toughness behavior and using this classification for comparison with other grades. Notched impact strength can provide a qualitative indication if the test samples fail under shock forces. Conditioning the design types with 55 % nitric acid for 21 days at 40 °C causes an increase in the marginal drop heights of the design types in drop tests at -18 °C when compared with design types without pre-storage. Post-crosslinking of the grades increases stiffness because of the acidic influence.

The environmental stress crack resistance determined by Full Notch Creep Test (FNCT) represents the impacts from the stacking tests at 40 °C performed with standard liquid wetting solution (without pre-storage) and with normal butyl acetate saturated wetting solution (pre-storage with normal butyl acetate). Environmental stress crack resistance determined with FNCT for the polyethylene grades was related to the times to failure of different jerrican samples made of these grades in stacking tests with 5% wetting solution and a n-butyl acetate saturated wetting solution (pre-storage with n-butyl acetate) at 40 °C. The FNCT is suitable for comparison of polyethylene grades in relation to environmental stress crack resistance independent of their use as drum, IBC or jerrican material. The stiffness of polyethylene grades should be taken into account to the comparison as jerricans are not only chemically but also mechanically stressed.
