Scope of Application
【Operating Instructions】
Applicable Scope:
Used for testing various hydraulic properties of geotextiles, geomembranes, and composite materials. It features multiple functions in one machine, including: testing the vertical and horizontal permeability coefficients of geotextiles, the hydrostatic pressure resistance and permeability coefficient of geomembranes, and the water flow rate of drainage boards.
Related Standards:
Complies with GB/T 15789, JTG E50, SL/T 235, ISO 11058, ASTM D 4716, and other related standards.
Technical Parameters:
Geotextile Vertical Permeability Holder Size: Φ50 mm ± 1 mm
Geotextile Horizontal Permeability Specimen Size: Φ100 mm × H40 mm
Geomembrane Hydrostatic Pressure & Permeability Coefficient Specimen Size: 200 mm (Perforated plate hole diameter: 3 ± 0.05 mm)
Geotextile Drainage Board Test Size: Φ70 mm × H440 mm
Pressure Range: 0 - 2.5 MPa
Measurement Methods:
Computer-controlled with automatic saving and printing of test results.
Pressure is measured simultaneously by a Class 0.4 pressure gauge and a pressure sensor, with an accuracy error of 0.2% F.S.
Geomembrane permeability is measured using a volumetric change tube and a volumetric change sensor, with an accuracy error of 0.2% F.S.
Other automated measurements; flow rate can also be measured using a graduated cylinder.
