ASTM D8151-19e1

5.1 A large number of erosion control product manufacturers produce a variety of RECPs and HECPs that are designed to be applied to any land surface to stabilize soils and prevent erosion. Many of these products are engineered to absorb moisture and remain in place even under extreme rainfall events and are composed of substances that could go into solution with runoff. Based on the characteristics of these products and their intended and actual use in the environment, the most likely scenario through which aquatic organisms would be exposed to these products or their soluble components is through storm water runoff. Further, because such runoff events typically last for minutes to hours rather than days, use of acute (48 h) toxicity testing methodology is appropriate to model expected environment exposures.

1.1 This practice establishes the guidelines, requirements, and procedures for obtaining rainfall runoff of unvegetated rolled and hydraulic erosion control products (RECPs and HECPs) during bench-scale conditions from simulated rainfall to be sent out for acute ecotoxicity testing.

1.2 This practice obtains unvegetated erosion control product (ECP) runoff from rainsplash-induced erosion under bench-scale conditions using bench-scale collection procedures.

1.3 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this test method.

1.5 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
