Standard Test Method for Determination of Sediment Retention Device (SRD) Effectiveness in Sheet Flow Applications

Importancia y uso:

5.1 This test method quantifies the effectiveness of a sediment retention device (SRD) by measuring the ability of the SRD to retain eroded sediments caused by sheet flowing water under full-scale conditions. This test method may also assist in identifying physical attributes of SRDs that contribute to their erosion control performance.

5.2 The effectiveness of SRDs is installation dependent. Thus, replicating field installation techniques is an important aspect of this test method. This test method is full-scale and therefore, appropriate as an indication of product performance, for general comparison of product capabilities, and for assessment of product installation techniques.

Note 1: Test Method D5141 is an alternate test method for evaluating sediment retention device effectiveness, if it is not necessary to simulate field installation conditions.

Note 2: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors: Practice D3740 provides a means of evaluating some of those factors.
