1.1 该试验方法可用作指数试验，以确定所有侵蚀控制毯（ECB）的单位面积质量。 1.2 所有观察值和计算值应符合实践中确定的有效数字和舍入准则 D6026 . 1.2.1 本试验方法中用于规定数据收集、计算或记录的方法与数据可用于设计或其他用途或两者的准确性没有直接关系。使用该试验方法获得的结果的应用超出其范围。 1.3 单位- 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 5.1 本试验方法用于确定ECB是否符合单位面积质量规范。该测量允许通过比较交付材料的单位面积质量和指定的单位面积质量来简单控制交付材料。 5.2 本测试方法中的程序可用于商业装运的验收测试，但由于实验室间精度信息不完整，因此建议谨慎。 5.3 本标准下的测试应符合实践要求 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. ====== Significance And Use ====== 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 .
