The average results from the two laboratories should be compared using the Student’s d47716 -test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. 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. For the best results, we recommend including the following details: Your message has been sent to the following suppliers.


ASTM D4716 Geosynthetic in-Plane Water Flow Rate Tester

Qstm to Active This link will always route to the current Active version of the standard. 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.

Features Diaphragmpressurizing High pressure, Keeping pressure long time, easy to maintain, can greatly reduce the testing cost. Forward Filter Manufacturers Co. Referenced Documents purchase separately The documents listed below are referenced within s4716 subject standard but are not provided as part of the standard. Recommended Quality Verified Suppliers.

Please reply me widthin 24 hours. I would like your verified suppliers matching service! Competent statistical assistance is recommended for the investigation of bias.

The flow of water within the plane of a ast, or geotextile-related product is measured under varying normal compressive stresses, with typical hydraulic gradients and with defined contact surfaces.

Comparative tests as directed in 5. 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. Application 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 is intended primarily as an index test but can be used also as a performance test when the asstm gradients and specimen contact surfaces are selected by the user to model anticipated field conditions.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result astk non-conformance with the standard. As a minimum, the two parties should take a group of test specimens that are as homogenous as possible and that are formed from a lot of the material of the type in question. Pressure Pump and Testing Cylinder Easy to operate, the result more d476.
