1.1 This test method covers the guidelines, requirements and procedures for evaluating the ability of Erosion Control Products (ECP) to protect slopes from rainfall-induced erosion using a tilting bed slope. Critical elements of this protection are the ability of the ECP to: 1.1.1 Absorb the impact force of raindrops, thereby reducing soil particle loosening and detachment through splash mechanisms; 1.1.2 Slow runoff and encourage infiltration, thereby reducing soil particle displacement and transport through overland flow mechanisms; 1.1.3 Trap soil particles beneath. 1.2 This test method utilizes large-scale testing procedures established at a variety of testing laboratories over the last 30 years.. 1.3 This test method provides a comparative evaluation of an ECP to baseline bare soil conditions under controlled and documented conditions. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to BG units, which are provided for information purposes only. 1.5 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D 6026, unless superseded by this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
