1.1 This practice establishes the guidelines, requirements, and procedures for obtaining unvegetated rainfall runoff from erosion control products (ECPs) during bench-scale conditions from simulated rainfall to be sent out for acute ecotoxicity testing via specified U.S. Environmental Protection Agency (EPA) testing methods. 1.2 This practice uses 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values shall conform to the guidelines for significant digits and rounding established in Practice D6026 unless superseded by this practice. 1.4.1 The procedures used to specify how data are collected/recorded in this practice are regarded as the industry standard.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 users 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 practice to consider significant digits used in analytical methods for engineering design. 1.5 This practice offers a set of instructions for performing one or more specific operations. This practice 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 International 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 practice be applied without consideration of a projects many unique aspects. The word Standard in the title means only that the practice 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 and health practices and determine the applicability of regulatory limitations prior to use.
No method exists. It will be used by DOTs and other agencies for product quality control and environmental approvals.
