Significance and Use
5.1 This test method determines the various fiber lengths that make up an HECP fiber mulch material. HECP fibers are engineered and processed to specific length and width dimensions that facilitate the hydraulic application and prevent clogging of the pump, recirculation pipes, nozzles, and tips.
5.2 This test method is used by manufacturers of HECP products for quality assurance testing.
1.1 This test method provides the requirements and procedures needed to determine quantitatively the fiber length percentages of hydraulic erosion control products (HECPs).
1.2 This test method allows for comparative evaluation of in-process HECPs to a manufactured product specification.
1.3 Units—The values stated in SI units are to be regarded as the standard. US standard units are provided in parentheses.
1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice .
1.5 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.
