TestResources 404D Series machine is designed according to ASTM D1709 standard test for impact resistance of plastic film by a free falling dart. The machine can used to test according to the practices of ASTM D1709 method A and method B. Method A uses an aluminum drop dart and Method B uses a stainless steel drop dart. Materials used with this machine include plastic film, plastic sheet, and lamination materials.

The 404D Series test machine also meets the requirement of ISO 7765-1, which has very similar content to ASTM D1709. Impact resistance of plastic films is determined by dropping a hemisphere dart head directly into the film from a specific height. The weight of the dropped dart is changed until a 50% failure rate of the film occurs.
