Tensile Properties of Plastics ASTM D638

In recent news, the ASTM D638Standard Test Method for Tensile Properties of Plastics has been under scrutiny. This widely used test method is used to determine the tensile properties of unreinforced and reinforced plastics under defined conditions of pretreatment, temperature, humidity, and testing machine speed.

However, concerns have arisen over the reliability and accuracy of this test method. Some experts have pointed out that the defined conditions may not accurately reflect real-world conditions, which could lead to inaccurate results and potentially faulty plastic products.


To address these concerns, a group of researchers is working to develop an updated test method that takes into account a wider range of environmental factors and better reflects real-world conditions. This updated method would help ensure more accurate and reliable results, and ultimately lead to safer and more reliable plastic products.

In the meantime, manufacturers and consumers alike are urged to exercise caution when relying on the results of the ASTM D638Standard Test Method for Tensile Properties of Plastics. It is important to consider additional factors, such as the intended use and exposure conditions of the plastic product, when assessing its safety and reliability.

As the global demand for plastic products continues to grow, it is essential that we have robust and reliable testing methods in place to ensure their safety and quality. The development of an updated test method for plastic tensile properties is an important step in this direction, and it is hoped that it will ultimately ensure safer and more reliable plastic products for all.
