New Test Method for Determining Index Nominal Diameter, Nominal Length and Volume Density of a Sediment Retention Fiber Roll (SRFR)
1. Scope
1.1 This test method is an index test method to determine the nominal diameter, nominal length, and volume density of a sediment retention fiber roll (SRFR) before installation. 1.2 The method used to specify collection, calculation, or recording of data in this test method is not directly related to the accuracy to which the data can be applied in design or other uses or both. Application of the results obtained using this test method is beyond its scope. Logistical and installation processes may make field measurements different than quality control measurements. NOTE 1--The extent of logistical deformation is not fully understood. The values produced from this test method are of a laboratory setting at the time of manufacturing; thus, they do not account for transformations that may be experienced during the logistical process of delivering product. Logistics may affect index properties such as, but not limited to, nominal diameter being reduced because of compression of materials during packaging and shipping. 1.3 This test method contains two procedures. Procedure 1 completely submerges the samples to provide conditions similar to those the material would be exposed to during a rainfall event. It is important to know how materials rebound when wetted after shipment because the resulting values are the index properties the material would have before it needed to perform in various outdoor applications. Procedure 2 evaluates the material at ambient conditions. 1.4 UnitsThe values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.5 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. 1.5.1 For purposes of comparing a measured or calculated value(s) with specified limits, the measured or calculated value(s) shall be rounded to the nearest decimal of significant digits in the specified limit. 1.5.2 The procedures used to specify how data are collected/recorded or calculated in the standard 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 standard to consider significant digits used in analysis methods for engineering design. 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, health and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 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.
