Significance and Use
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.
Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice does not in itself assure reliable results. Reliable results depend on many factors; Practice provides a means of evaluating some of those factors.
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 .
1.2.1 For purposes of comparing measured or calculated value(s) with specified limits, the measured or calculated value(s) shall be rounded to the nearest decimal or significant digits in the specified limits.
1.2.2 The procedures used to specify how data are collected/recorded or calculated, in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be measured. 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 the significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in the analytical methods for engineering design.
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.
