Historical Version s – view previous versions of standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Some modification of ASTM D techniques may be necessary for a given geogrid depending upon its physical make-up.
Combining values from the two systems may result in non-conformance with the standard. The determination of the ASTM D tensile force-elongation values of geogrids provides index property values. This ASTM D single or multi-rib tensile test of geogrids test method covers the determination of the tensile strength properties of geogrids by subjecting strips of varying width to tensile loading. 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.
Special adaptations may be necessary with strong geogrids, multiple layered geogrids, or geogrids that tend to slip in the clamps or those which tend to be damaged by the clamps. This standard does not purport to address all of the safety concerns, if any, associated with its use.
Active Risk Management
We are confident that we have what you are looking for. If a 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. Work Item s – proposed revisions of this standard.
Competent statistical assistance is recommended for the investigation of bias. Give our test engineers a call today for help configuring the best test machine and accessories according to ASTM D Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
ASTM D Single or Multi-Rib Tensile Test of Geogrids
As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question. Special adaptations to the ASTM D methods may be necessary d667 strong geogrids, multiple layered geogrids, or geogrids that tend to slip in the clamps or those which tend to be damaged by the clamps.

We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. This test method shall be used for quality control and acceptance testing asym commercial shipments of geogrids. The average results from the two laboratories should be compared using Student’s t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing began.
