Plastic Tensile Test GB1040-2006

Plastic Tensile Test GB1040-2006


This part of GB1040-2006 applies to dumbbell shaped (type I-V), rod shaped and tubular sample types to specify test conditions for determining the tensile properties of unreinforced and reinforced plastic materials. These properties include tensile strength, tensile strain at break, and tensile modulus of elasticity.

detailed information


There are many factors affecting the mechanical properties of plastics, including the influence of polymer structure (such as polymer type, molecular weight and its distribution, whether it is crystalline, etc.), and the influence of molding processing (such as the change of crystallinity and orientation degree caused by molding processing methods and processing conditions, and the defects of samples, etc.); The influence of test conditions (such as test temperature, humidity, speed, etc.) will lead to defects such as poor repeatability of the experiment.

◇ Test instrument

◎ Sample preparation instrument: one tablet processor; Or more than five standard samples with injection molding machine

◎ Test equipment host: CMT4104/CMT1104 plastic tensile testing machine

◎ Test equipment accessories:


• Electronic extensometer: used to calculate the tensile elastic modulus. Most plastic materials have similar properties, and the extensometer is required to accurately measure the deformation. The plastic stress deformation curve usually contains a linear elastic region and a nonlinear plastic region. Very few deformations occur in the linear region, and since the modulus is measured in this region, a high-resolution extensometer is necessary.


• Fixture: We recommend using mechanical wedge clamp or pneumatic flat pushing clamp for plastic tensile test.


Large deformation measurement system: used to calculate tensile strain at break
