Geotextile / Geosynthetics Testing Instruments
MI.GE-1009 Hydrodynamic Sieve Test Apparatus
Meets: - EN ISO 12956:199
The percentage passing of different fractions determines the porometry of the geotextile investigated. In the Hydrodynamic Sieving Method, the geotextile specimen, loaded with a certain quantity of glass bead fraction, is continuously rotated in a water trough, forcing the glass beads to pass through the geotextile openings. Glass beads to be ordered separately
MI.GE-1010 Interface Friction Test Apparatus
Meets: - ASTM D 5321 - 02, EN ISO 12957-1:200
This test method covers a procedure for determining the shear resistance of a geosynthetic against soil or a geosynthetic against another geosynthetic, under a constant rate of deformation.
Note: - Direct shear apparatus is to be order separately.
MI.GE-1011 Abrasion resistance of geotextile
Meets:-ASTM-D 4886-91, IS-14714, EN ISO 13427:199
This test method covers the determination of resistance of geotextiles to abrasion using an abrasion tester. This test method at this point has only been evaluated for geotextiles- not geomembranes, grids, etc. Therefore, the test method is designated for geotextiles, not geosynthetics, as all products may not lend themselves to this test method for abrasion. If later developments indicate a wider scope for this test method, appropriate changes will be made. The assembly should be two parallel, smooth plates, one of which makes a reciprocating motion. The speed of the reciprocating plate should be adjustable between 10 and 115 double strokes per minute. The stroke length should be 25 mm (1 in.). The second plate is rigidly supported by a double-lever assembly to provide free movement in a direction perpendicular to the reciprocating plate. This plate is stationary during the test and must be well balanced so that a vertical load can be maintained by means of dead weights. Both plates are equipped with clamps at each end to hold the test sample and the abrading medium. The clamps have gripping surfaces adequate to prevent slippage of the specimen or the abrading material during the test.
MI.GE-1012 Creep tester
Meets: - IS-14739
It consists of a loading frame for the specimen to be mounted, the load to be correctly applied, and strain monitored. The connections between jaws and loading apparatus have sufficient freedom that the load is applied uniformly across the width of the specimen. The jaws shall grip the specimen with sufficient firmness to allow minimum slippage.
MI.GE-1013 Environmental Chamber
Meets: - ASTM D-4594
This chamber is capable of maintaining a temperature range from ? 40 to + 100°C and controlled by the PID controller for better accuracy.
