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.

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.

Testing under this standard shall conform to the requirements of Practice D 3740

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 This test method requires several hours for proper drying of the specimen in an oven at high temperature.

1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D 6026.

1.3.1 The method used to specify collection, calculation, or recording of data in this standard is not directly related to the accuracy to which the data can be applied in design or in other uses, or both. Application of the results obtained using this standard is beyond its scope.

1.4 The values stated in SI units shall be regarded as standard. The values stated in parentheses are provided for information only.

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.
