Dynstat Flexure and Impact Bending Test to DIN 53435
If, for lack of space, only relatively small specimens can be taken from injection-molded parts, the two Dynstat test methods offer interesting options for the comparative characterization of static and dynamic material properties in quality assurance and product development. Standard DIN 53435 was completely revised and updated in 2017 and the contents of DIN 53435 and its associated instrument standard,DIN 51230 , were combined. By aligning this standard with other standards for impact testing, ISO 179-1 for Charpy, ISO 180 for Izod and ISO13802 regarding instrument characteristics and calibration, the body of standards are now standardized and up to date with current technology. The use of notch type A for Dynstat impact bending tests is new to this standard. This notch type is also used in Charpy and Izod standards. A flexure tool with electronic torque measurement has been introduced for static flexure tests. Precision data collected from these test methods and the notch types now approved provide clues to possible areas of application.
