Thermoplastics and thermosetting molding materials

  • A key aspect of the characterization of molding materials is the inter-laboratory reproducibility of test results.
  • Specimen production, specimen shapes, and test sequences are all specified in detail,
  • with rigorous demands on both repeatability and traceability.
  • In the area of quality control, the development of properties over time and compliance with specified tolerances are the essential evaluation standards.
