ASTM D3029 Test Standard for Impact Strength Through Flat, Rigid Plastic Specimens

The ASTM D3029 standard, published by the American Society for Testing and Materials (ASTM), covers the determination of the relative ranking of materials according to the energy required to crack or break flat, rigid plastic specimens under various specified impact conditions of a free-falling pile or weight.

Values ​​stated in SI units should be accepted as standard. Values ​​in parentheses are for informational purposes only. This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.

The energy required to burst and penetrate the center is measured by the loss in span, mechanical work capacity of a sample mounted between a circular plate and two plates. Due to the dissipation of kinetic energy by a pendulum, corrections for the round probe throw factor or kinetic energy passing through the test sample cannot be made on the puncture part of the test sample because only small masses are involved.

Like other techniques used to measure toughness, this test method provides a means of determining the parameters of a material. Visualized by low-speed uniaxial tensile tests at strain rates closer to some end-use applications. Dynamic shrinkage is the behavior of a film, especially the film is used as a packaging material. The same uncertainties are valid for other impact tests, and the correlations with thickness are also valid for this test. Therefore, there is no provision for rationalization to unit thickness.

With the experience gained over many years, our organization provides ASTM D3029 standard testing services to the demanding enterprises, with a trained and expert staff, within the framework of laboratory services of materials.
