Plastics Testing

Basic identification of plastic can be accomplished by using three analytical plastics tests. FTIR (ASTM E1252), EDS, and TGA (ASTM E1131) analyses. A typical summary statement for a basic material identification report might read “The FTIR, EDS, and TGA analysis of the sample was consistent with that of a polycarbonate with 10% glass filler.” This combination of tests provides basic information but additional testing is needed if identification of a trace additive or the grade of plastic is required.

There are a wide variety of tests used for mechanical testing of plastics but some of the more common are Tensile Properties (ASTM D638), Flexural Properties (ASTM D790), and Izod Impact Strength (ASTM D256). Mechanical testing is most often performed on molded test bars but we also have a complete machine shop so we can fabricate test bars out of stock material or even parts.

Plastic used in electrical applications often requires testing such as Dielectric Strength (ASTM D149), Dielectric Constant (ASTM D150), Volume Resistivity (ASTM D257), or Surface Resistivity (ASTM D257). These tests are typically performed on flat plaques.
