5.1 This index test method indicates a unvegetated RECP’s ability to reduce rainsplash-induced erosion under bench-scale conditions. This test method may also assist in identifying physical attributes of RECPs that contribute to their erosion-control performance. 5.2 This test method is bench-scale and therefore, appropriate as an index test for initial indication of product performance, for general comparison of unvegetated RECP capabilities, and for product quality assurance/conformance testing. The results of this test are not indicative of an RECP’s actual field performance. 1.1 This index test method
establishes the guidelines, requirements and procedures for
evaluating the ability of unvegetated rolled erosion control
products (RECPs) to protect soils from simulated rainfall (rain
splash) and minimal runoff induced erosion. The critical element of
this protection is the ability of the unvegetated RECP to absorb
the impact force of raindrops, thereby reducing soil particle
loosening through “splash” mechanisms, and limiting the ability of
runoff to carry the loosened soil particles.
1.2 This index test method utilizes bench-scale testing procedures and is not indicative of unvegetated RECP performance in conditions typically found in the field. 1.3 This index test is not intended
to replace full-scale simulation or field testing in acquisition of
performance values that are required in the design of erosion
control measures utilizing unvegetated RECPs.
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.5 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this standard. 1.5.1 The procedures used to specify how data are collected/recorded or calculated in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives, and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this index test method to consider significant digits used in analytical methods for engineering design. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use and may involve use of hazardous materials, equipment, and operations. 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. Also, the user must comply with prevalent regulatory codes, such as OSHA (Occupational Health and Safety Administration) guidelines, while using the index test method. |
