JTG E50-2006 T1130 Highway Engineering Geosynthetic Materials Test Specification Tensile Friction Characteristics Test 3. SL235-2010 Hydraulic test regulations for geotechnical materials 4. GB/T17635.1-98 Determination of friction characteristics of geotextiles and related products Note: Meet the above criteria, but are not limited to the above criteria; [Instrument features]: 1. This machine is multi-purpose, which can not only do the direct shear friction test of geotechnical materials, but also test the pull-out friction test of geotechnical materials. 2. The normal force dynamic test system is controlled by microcomputer servo, and the normal force test unit Mpa, Kpa, kgf/mm², N/mm², N/cm² are optional, and the force value and area data can be directly displayed; 3. The shear stress is directly converted into kilopascals in the test program, no manual conversion is required, the normal force and shear force are servo drive system, dynamic load adjustment system, and the test data is accurate. 4. The all-stainless steel worktop is easy to clean and finish, effectively preventing soil particles from entering the inside of the instrument. 5. The software has a software test report certificate issued by the national inspection and testing agency, and the test report must reflect the “CMA” logo. 6. The dynamic data collection frequency is more than 3000 times per second, which more objectively reflects the mechanical properties of the material; 7. Philips RM32-bit industrial-grade microcontroller control, 16-bit A/D converter, strong anti-interference performance, fast data transmission; 8. The computer processes reports, graphics, screen display or printout; Support software remote online upgrade 9. Operation software system function: The instrument can be connected with the PC: record the whole process of the test, display the curve, shear force, pull force in real time, and calculate the test date, shear stress, horizontal displacement and other data and curve charts. It can analyze the data change process at each stage of the test process in detail, and the data of various statistical indicators such as CV value can be saved and can be exported to an Excel sheet. 【Technical Parameters】: 1.
