It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

If bias is found, either its cause must be found and corrected or the purchaser and supplier must agree to interpret future test results in light of the known bias. The test is intended primarily as an index test but can be used also as a performance test when the hydraulic gradients and specimen contact surfaces are selected by the user to model anticipated field conditions.

I would like your verified suppliers matching service! Geotextile Water Flow Capacity Tester, to determing the constant-head water flow capacity within the plane of a geotextile or geotextile-related product.


The test specimens should then be randomly assigned in equal numbers to each laboratory for testing.

Your email address is incorrect! Application Geotextile Water Flow Capacity Tester, to determing the constant-head water flow capacity d4761 the plane of a geotextile or geotextile-related product. Pressure Pump and Testing Cylinder Easy to operate, the result more accurate. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Features Diaphragmpressurizing High pressure, Keeping pressure long time, easy to maintain, can greatly reduce the testing cost.

The average results from the two laboratories should be compared using the Student’s t -test for d44716 data and an acceptable probability level chosen by the two parties before the testing is begun. The flow of water within the plane of a geotextile or geotextile-related product is measured under varying normal compressive stresses, with typical hydraulic gradients and with defined contact surfaces.

Combining values from the two systems may result in non-conformance with the standard. Your message must be betweencharacters!
