1. Scope

1.1 This test method provides a quantitative test method to determine the specific strength of hydraulically applied fiber matrix products using dry and wet preparation methods in a laboratory setting. This test method is designed for use as an index test for product quality assurance or quality control or both to comply with manufacturing requirements. This test method is not indicative of product performance in the field. 1.2 Units-The values stated in SI units are to be regarded as the standard. The values given in parentheses are mathematical conversions to inch-pound units, which are provided for information only and are not considered standard. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard. 1.3 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values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this test method. 1.3.1 The procedures used to specify how data are collected/recorded and calculated in this test method are regarded as the industry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 these test methods to consider significant digits used in analysis methods for engineering data. 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, health and environmental 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.

Keywords

breaking strength; erosion control; hydraulically applied fiber matrix products; specific strength; tensile

Rationale

Specific strength is a measure of the ability of a fiber matrix product to withstand force applied by a tensile machine. Strength is frequently related to the matrix density, fiber quality, fiber length, and chemistry and can be used as an measurement for quality assurance or quality control requirements or both. Manufacturers and agencies will be the users.
