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. The average results from the two laboratories should be compared using the Student’s t -test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun.

The test specimens should then be randomly assigned in equal numbers to each laboratory for awtm. Your message must be betweencharacters! Send your message to this supplier.

Competent statistical assistance is recommended for the investigation of 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.

If bias is found, either its cause must be found and corrected or the purchaser satm supplier must agree to interpret future test results in light of the known bias.

ASTM D4716 ISO12598 Geotextile in-Plane Water Flow Rate Test Apparatus

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