ASTM D7986-17a

5.1 This practice is intended to simulate mixing of HECP products as would be mixed on a job or project site but in a laboratory environment on a smaller scale. Dried samples are not necessarily intended to represent a field application of HECP products but would be representative of the correct amount of material applied to a known area and provide a basis for consistent and repeatable index property testing.

1.1 This practice specifies a set of instructions for preparing samples of hydraulic erosion control products (HECPs) for index property testing.

1.2 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.

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

1.4 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.

1.5 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.
