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

ASTM D6693 Tensile Test of Geomembranes

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. Tensile properties may provide useful data for plastics engineering design purposes. Link to Active This link will always route to the current Active version of the standard. This test method is not intended to cover precise physical procedures.

Special additional tests should be used where more precise physical data are needed. Combining values from the two systems may result in non-conformance with the standard. Referenced Documents purchase separately D66993 documents listed below are referenced within the subject standard but are not provided as part of the standard.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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 cannot be considered valid for applications involving load-time scales or environments widely different from those of 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, and that these variations may influence the test results. Link to Active This link will always route to the current Active version of the standard. Therefore, it is advisable to refer to that material’s specification before using this test method.

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. Asstm may be necessary ast modify this procedure for use in testing certain materials as recommended by the material specifications.

Special additional tests should be used where more precise physical data are needed. The values given in parentheses are for information only.

These data are also useful for qualitative characterization and asttm research and development.

A wide difference may exist atsm 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 aetm plastic state.
