Safety: This machine shall conform to all relevant European CE Health and Safety Directives EN 50081-1, 580081-1, 73/23/EEC, EN 61010-1.
Specimen is ‘X’ style, which is fixed in the center of the testing machine. The four boundaries of the specimen are fixed by the grip. The displacement sensor is fixed in the center of specimen. As equipment that applying load, the servo motor is fixed at the bottom of leading screw, and at the same time, the value of load is recorded by sensor. There is a displacement sensor at the center of specimen which can transfer the value of displacement. Using these data, the software can protract load-displacement curve. As the two servo motor are located in two directions (warp and weft) and can work at the same time, this biaxial tensile machine can do biaxial test and to-and-pro test.
The biaxial tensile testing machine consists of mechanical system and control system: mechanical system includes load frame, membrane specimen fixtures, servo motors(Japan), load sensors, displacement sensor and other components, while control system with the computer and software;
