ASTM D638–Compliant Tensile Testing of Plastics

User Benefits

- Tensile testing of plastics conforming to ASTM D638 is possible.

Introduction

Tensile properties are basic evaluation items for understanding the characteristics of plastic materials. Mechanical properties such as strength, elastic modulus, and elongation can be quantitatively evaluated by investigating the stress-strain behavior when a tensile load is applied to the material. This makes it possible to obtain indices for understanding the strength and deformation behavior of the material under the actual use environment. ASTM standards are established by ASTM International, and ASTM D638 specifies the test piece geometry and test conditions for tensile tests of plastics. Since compliance with this standard enables data acquisition under uniform conditions, it is widely used as a test method for objective comparisons of differences between materials and various molding conditions. This article introduces an example of tensile testing of plastics conforming to ASTM D638 (revision of December 15, 2014) using a Shimadzu AGS-V precision universal testing machine.
