Significance and Use
5.1 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 B212, B329, and B417.
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 With the exception of the values for density and the mass used to determine density, for which the use of the gram per cubic centimetre (g/cm3) and gram (g) units is the long standing industry practice, the values in SI units are to be regarded as standard.
