A falling dart impact tester measures the impact resistance of plastic film and thin sheet by dropping a hemispherical dart of known weight from a fixed height onto a clamped film specimen. Using the staircase method, the dart weight is increased or decreased depending on whether the previous specimen failed, until the weight that causes 50% of specimens to fail is determined. This 'impact failure weight' characterises the film's toughness.
Dart impact testing to ASTM D1709 and ISO 7765 is a standard quality-control test for blown and cast film producers, agricultural film makers, and flexible-packaging converters. It quickly detects changes in film toughness caused by resin grade, processing conditions or the addition of recyclate, and is often specified by film buyers as an acceptance criterion.
Consider whether you need Method A (26-inch drop) or Method B (60-inch drop), the range of dart weights supplied, and the pneumatic clamping system that holds the film flat and repeatably. International Equipments supplies dart impact testers with the dart sets and clamping arrangements required by ASTM D1709 Methods A and B.
