Standard Test Method for Un-notched Cantilever Beam Impact Resistance (Izod Impact) Testing of Thermoplastic Pavement Marking Materials

Importancia y uso:

5.1 The significance of this test is to determine the thermoplastic pavement marking material’s resistance to impact, under laboratory conditions. The method provides a numerical result for impact failure which can be used to assess quality and determine relative performance between materials.

5.2 When the pendulum-impact test is performed on thermoplastic pavement marking materials, the results can indicate the strength and brittleness properties helpful in researching and improving their field durability. Anyone attempting to perform this test should initially review Test Methods D256 and Test Method D4812; especially the equipment setup.

5.3 The following sample preparation and testing setup method is important so inconsistencies in sample preparation do not cause more inconsistency in the results that are inherent when testing thermoplastic pavement marking materials.
