Further, it is realized that variations in the thicknesses of test specimen, as permitted by this test standard, produce variations in the surface-volume ratios of such specimens, and that these variations may influence the test results.

These data are also useful for qualitative characterization and for research and development. Link to Active This link will always route to the current Active version of the standard.

It may be necessary to modify this procedure for use in testing certain materials as recommended by the material specifications. Combining values from the two systems may result in non-conformance with the standard. Special additional tests should be used where more precise physical data are needed.

This test method is not intended to cover precise physical procedures.

ASTM D Tensile Test of Geomembranes

A wide difference may exist between the rate of crosshead movement and the rate of strain of the specimen indicating that the testing speeds specified may disguise important effects or characteristics of these materials in the plastic state. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are e6693 provided as part of the standard. Hence, where directly asmt results are desired, all samples should be of equal thickness.

Further, it is realized that variations in the thicknesses of test specimens, asfm permitted by this test method, produce variations in the surface-volume ratios of such specimens, and that these variations may influence the test results.

The constant rate of crosshead movement of this test lacks accuracy from a theoretical standpoint. Hence, where directly comparable results are desired, all samples should be of equal thickness. Tensile properties may provide useful data for plastics engineering design purposes.

Hence, when comparative tests of materials are desired, the care must be exercised to ensure that d66933 samples are prepared in exactly the same way, unless the test is to include the effects of sample preparation.

Similarly, for referee purposes or comparisons within any given series of specimens, care must be taken to secure the maximum degree of uniformity in details of preparation, treatment, and handling. A wide difference may exist between the rate of crosshead movement and the rate of strain of the specimen indicating that the testing speeds specified may disguise important effects or characteristics of these materials in the plastic state.

The constant rate of crosshead movement of this test lacks accuracy from a theoretical standpoint.

Consequently, where precise comparative results are desired, these factors must be carefully monitored and controlled. 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.

However, because of the high degree of sensitivity exhibited by many plastics to rate of straining and environmental conditions, data obtained by this test method adtm be considered valid for applications involving load-time scales or environments widely different from those of this test method.

The values given in parentheses are for information only. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. This sensitivity to rate of straining and environment necessitates testing over a broad load-time scale and range of environmental conditions if tensile properties are to suffice for engineering design purposes. Historical Version s – view previous versions of standard.

Special additional tests should be used where more precise physical data are needed. Therefore, it is advisable to refer to that material’s specification before using this test method. In cases of such dissimilarity, no reliable estimation of the limit of usefulness can be made for most plastics.
