ASTM D1822 Standard Test Method for Tensile-Impact Energy to Break Plastics and Electrical Insulating Materials
The ASTM D1822 test measures the energy required to break electrically insulating or plastic specimens under standard tension impact, evaluating resistance to combined tensile and impact pressures, toughness, and durability. The ASTM D1822 test calculates the energy needed to break a plastic specimen based on these combined forces. The ASTM D1822 test method covers the determination of the energy required to rupture standard tension-impact specimens of plastic materials. Rigid materials are suitable for testing by the ASTM D1822 method as well as specimens that are too flexible or thin to be tested in accordance with other impact test methods.

Introduction to ASTM D1822
Tensile-impact energy is the energy required to break a standard tension-impact specimen in tension by a single swing of a standard calibrated pendulum under a set of standard conditions. ASTM D1822 evaluates plastics’ tensile-impact resistance, crucial for suitability in engineering and industrial settings. Subjecting standardized specimens to controlled forces provides insights into material toughness, mechanical stress resistance, and performance. ASTM D1822 helps manufacturers, researchers, and engineers select suitable materials for specific applications, enhance product design, and ensure safety and reliability.
The energy for fracture is a function of the force times the distance through which the force operates. Therefore, given the same specimen geometry, it is possible during ASTM D1822 test that one material will produce tensile-impact energies for fracture due to a large force associated with a small elongation, and another material will produce the same energy for fracture result due to a small force associated with a large elongation. The ASTM D1822 test method may not correlate with other tests or end uses unless such a correlation has been established by experiment
ASTM D1822 Test Procedure
Specimen Selection
ASTM D1822 specimen considerations include composition, processing method, and additives. A minimum of five specimens is recommended for statistical significance and reliable results.
Test Setup and Execution
Test specimens are curated in a controlled environment to prevent moisture or temperature variations. The ASTM D1822 testing machine applies tensile and impact forces simultaneously, and the specimen is struck by a striker or pendulum. Data collection, calculations, analysis, and reporting are conducted, and a test report is generated. Repeatability is ensured by repeating the test with additional specimens from the same material batch.
ASTM D1822 Test Specimens
Specimen Details
ASTM D1822 test specimens are made from plastic with a “dumbbell” or “dogbone” shape, ensuring stress concentration for accurate, consistent results in tensile-impact resistance testing.
Specimen Dimensions
The ASTM D1822 standard defines dumbbell-shaped specimens with dimensions of 115mm in length, 12.5mm in width at the center, 6.4mm in width at the narrow portion, and 3.2mm in thickness. These dimensions may vary depending on the type of plastic and standard version.
ASTM D1822 Test Results
The test measures the peak force applied to a specimen, indicating its resistance to tensile and impact forces. It calculates the total energy absorbed by the specimen before failure, indicating its capacity to dissipate energy and resist crack propagation or rupture. The test also measures the tensile strength, elongation at break, modulus of elasticity, and type of failure, indicating the material’s ductility and stiffness. The test also determines the material’s resistance to deformation and stiffness.
