The tensile test according to ISO 527-1 can be used to determine key mechanical properties of plastics such as tensile strength, yield strength and modulus of elasticity.

With its various test area extension options, the inspekt duo 10 kN tensile testing machine is the ideal choice for numerous testing applications on plastics and other materials with high elongation. Equipped with pneumatic grips and a control unit, the clamping pressure can be controlled and regulated over the entire tensile test. This ensures the reproducibility of the tensile test and also enables thin plastic films to be tested.

The machine also has a force-holding mode that minimizes compressive stresses that occur due to clamping, for example. This prevents pre-damage, especially to force-sensitive samples. This is recommended for materials such as fiber-reinforced plastics or films in order to avoid undesirable influences on material characteristics. Axial clamping of the tensile specimens is ensured by means of specimen depth stops so that no transverse forces impair the test results.

The testing machine and clamping fixtures can be controlled directly at the machine using manual operation, which makes the operator's work easier and optimizes work processes when testing large quantities. Alternatively, operation via the LabMaster testing software is also possible. Here, for example, the test parameters for different sample shapes and materials can be entered.

Another component of the testing system is the MFE910-1 long distance extensometer, which determines elastic parameters such as the tensile modulus using an inductive fine measuring range in accordance with method B as per DIN EN ISO 527-1. Due to the high measuring path, the other measured values such as the equivalent yield point or yield strength and the elongation at break for plastics/elastomers with high elongation can be determined.
