ASTM D6693 Tensile Test of Geomembranes

Hence, where directly comparable results are desired, all samples should be of equal thickness. Special additional tests should be used where more precise physical data are needed. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

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.

ASTM D Tensile Test of Geomembranes

Consequently, where precise comparative results are desired, these factors must be carefully monitored and controlled. Further, it is realized that variations in the awtm 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.

Hence, where directly comparable results are desired, all samples should be of equal thickness.

Hence, when comparative tests of materials are desired, the care must be exercised to ensure that all samples are prepared in exactly the same way, unless the test is to include the effects of sample preparation. 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. The constant rate of crosshead movement of this test lacks accuracy from a theoretical dd6693.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory axtm prior to use. The constant rate of crosshead movement of this test lacks accuracy from a theoretical standpoint. Active view current version of standard. 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.

In cases of such dissimilarity, no reliable estimation of the limit of usefulness can be made for most plastics. These data are also useful for qualitative characterization and for research and development. A wide difference may exist between the rate of 6d693 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.

Therefore, it is advisable to refer to that material’s specification before using this test method. Further, it is realized that variations in the thicknesses of test specimens, as permitted by this test method, produce variations in the surface-volume ratios of such specimens, aetm that these variations may influence the test results.

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

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. However, because of the high degree of sensitivity exhibited atsm many plastics to rate of straining and environmental conditions, data obtained by this test method cannot be considered valid for applications involving load-time scales or environments widely different from those of this test method.
