Standard Test Method for Strength of Sewn or Bonded Seams of Geotextiles

Importancia y uso:

5.1 As explained in Test Method D4595, narrow geotextile specimens demonstrate the tendency to contract (neck down) in the gauge area when under stress. The wider width specimen will minimize this phenomenon in seams during strength testing. The results achieved in this test method can more accurately correlate to the seam strength values anticipated in the field.

5.2 This test method can be used to measure the seam strength of geotextiles from the factory or field, and may also be used for acceptance testing of commercial shipments of geotextiles.

5.3 This test method can be used to help determine seam design engineering for the geotextiles being evaluated, as well as comparing wet-conditioned specimens with dry specimen results.

5.4 This test method is not intended to address long-term performance of a seam, nor any of its components such as the thread or the adhesive. However, it can be used as an index value to monitor the behavior of a seam exposed to any particular exposure, in example as part of an effort to assess its long-term performance.
