Material Testing & Inspection

Introduction

The physical characteristics of plastic materials are an essential part of product design and quality control. Various materials tests are performed because of this, of which the most basic test is tensile testing that is cited in many product specifications. The tensile properties of plastic materials assessed by tensile testing include strength, elastic modulus, and breaking strain. Tensile testing of plastics was once performed according to the standard test methods described in ISO 527-1 (JIS K 7161), but ISO 527-1 was revised substantially in 2012 (and JIS K 7161 in 2014). This revision resulted in a number of important changes, of which the main changes are summarized below.
