Phạm vi áp dụng / Scope of standard

This method is for the rapid determination of the maximum dry density and optimum moisture content of a soil sample using a one-point determination and an individual moisture/density curve or a family of curves.

The following applies to all specified limits in this standard: For the purposes of determining conformance with these specifications, an observed value or a calculated value shall be rounded off "to the nearest unit" in the last right-hand place of figures used in expressing the limiting value, in accordance with the rounding-off method of ASTM E29.

The values stated in SI units are to be regarded as the standard.
