Information about tests

Dart Drop Test (Impact resistance)

ASTM D 1709/ ISO 7765-1; free falling dart method, method A (thinner films mf >0,05 kg), method B (stronger films mf > 0,3 kg)

test method:Mechanical/ technological properties
Norms:DIN EN ISO 7765-1 / ASTM D 1709
Needed sample size:Sample over total width of material, minimum length: 3 m


dart drop method A mf = 0.05 - 1 kg
Especially for thinner films with lower Dartdrop strength (eg PE-films with a thickness < 100 microns)

dart drop method B mf = 0.3 - 1 kg
Especially for thicker films with higher Dartdrop strength (e.g. PE-films with a thickness >100 microns)
