    Comprised of the most current and wide-ranging information available on metallic and nonmetallic pendulum impact machines. Experts from all over the world have contributed 18 papers covering four major areas: The Specimen; • The Anvils and the Striker; • Establishing Reference Energies; • and Testing Procedures and Other Topics.

    Three papers compare the merits of two different radius striker designs. Several presentations focus on the development of standardized specimens and their impact on verification of machine performance.

    Machine and specimen tolerances are explored in five papers, covering such topics as striker geometry tolerances, striker surface finish, specimen edge and reconstitution of specimens.

    Machine verification in plastic and polymeric materials is also discussed.

    Other papers deal with kinetic energy from the machines as well as the use of load-displacement curves for impact tests.
