【国外标准】 Standard Test Method for Measuring Mass per Unit Area of Erosion Control Blankets

5.1 This test method is used to determine if the ECB meets specifications for mass per unit area. This measurement allows for a simple control of the delivered material by a comparison of the mass per unit area of the delivered material and the specified mass per unit area.5.2 The procedure in this test method may be used for acceptance testing of commercial shipments, but caution is advised since information about between-laboratory precision is incomplete.5.3 Testing under this standard shall conform to the requirements of Practice D3740.1.1 This test method can be used as an index test to determine the mass per unit area of all erosion control blankets (ECBs).1.2 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.1.2.1 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.1.3 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.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.
