ASTM B873-01(2007)

1.1 This test method covers a procedure for measuring the volume of the apparent density cups used in Test Methods B 212, B 329, and B 417.

1.2 The apparent density cup, particularly its rim, may become worn during use, and it is recommended that the volume of the cup be checked periodically (at least every 6 months) in order to ensure that it complies with the specified volume.

1.3 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.

This test method enables the measurement of the volume of the apparent density cup to ensure that it complies with the specified volume of 25.00 ± 0.03 cm³ (cylindrical cup), or 16.39 ± 0.05 cm³ (square cup). Use of an out-of-specification cup will give erroneous apparent density values using the formulae in Test Methods B 212, B 329, and B 417.
