Product Description
1. Applications & functions of Geotextiles Tensile Testing machine
WDW series Geotextiles Tensile Testing machine are used for wide width strength and elongation, grab strength and elongation, CBR puncture test and trapezoidal tear test of geotextiles. They are essential testing instrument for quality testing section, university and college, research institution and industrial and mining enterprise.
2. Main Features of Geotextiles Tensile Testing machine
This machine adopts the most advanced and reliable load frame structure of ball screw electric mechanical universal testing machine, which equips alternating servomotor for driving crosshead, photoelectric encoder for displacement measure and high precision load cell to assure the high resolution of test.
Equipped with the computer &Software & printer, it can display, record, process and print the test results, and control test procedures as the set program and can draw test curves automatically in real time. Control software can automatically finger out routine data, such as tensile modulus of elasticity, extend rate after rupture, non-proportional extend strength Rp0.2, etc.
They can conform to the requirements of testing standards ASTM D4595, ASTM D4632, ASTM D6241, etc.
