Tensile Test of Plastic with SIE-560SA Automatic Extensometer (ISO 527 and JIS K7161) - Tensile Test of Plastics with Automatic Extensometer

User Benefits

- Compliance with ISO 527 (JIS K 7161) regulation - Significant test time reduction

Introduction

Plastic materials have excellent formability and versatility, and are widely employed as structural/functional material in several fields ranging from aircraft parts to electronic components. During the design/quality control phase, the measurement of the material mechanical properties is essential to ensure high reliability and safety of the products. The typical material properties are the tensile strength and the elastic modulus, both evaluated with a tensile test. Such tests must be conducted following the guidelines of regulations (national or international) in order to guarantee a high repeatability and reliability of the measurements. When tensile tests are conducted for quality control, numerous tests must be repeated every day and a reduction of the test time is key to optimize the inspection process. Effective methods to reduce the test time include the employment of extensometers capable of setting the arm position and grip the specimen automatically, such as the SIE-560SA. In this work, the precision universal testing machine AGX-10kNVD and the automatic extensometer SIE- 560SA were employed to test 3 varieties of plastic materials (PVC, PP, PC) according to the ISO 527 (JIS K 7161) standard.
