Testing thermoplastic & curable molding materials

A key aspect of the characterization of molding materials is the inter-laboratory reproducibility of test results. The machining of specimens, specimen shapes, and test sequences are all specified in detail in the respective test standards. Tensile tests on plastics according to ISO 527 or ASTM D638, flexure tests according to ISO 178 or ASTM D790 are a few important examples. Both the repeatability and traceability capabilities, which ensure reliable test results, are subjected to strict requirements. In the area of quality control , the development of properties over time and compliance with specified tolerances are the essential evaluation standards.

Some of the most important tests on thermoplastic and curable molding materials and associated test standards can be found in the following overview:
