Dart Drop Impact - ISO 7765-1
The weight required to cause 50% of tested films to failure by impact from a falling dart under specified test conditions. Impact resistance is only partially thickness dependant, as a result impact values cannot be normalized by thickness without producing misleading data.
|Method||Dart Head Diameter||Drop Height|
|A||38 mm||0.66 m|
|B||50 mm||1.50 m|
