Density at 15 °C (table derived from ASTM-IP 53, 1986)
Observed density from 455–500 kg/m3 corrected to actual density kg/m3

Note:If the corrected density table value is empty, the observed density and temperature combination is invalid. If the corrected density table value is three digits long and in a shaded cell, the observed density and temperature combination is suspect. Double-check your data and ensure that necessary corrections have been made to the standard’s readings

Density at 15 °C
Values derived from ASTM-IP Table 53 (1986)

To obtain the corrected density at 15 °C, find the observed density and temperature. The corrected density at 15 °C appears in the cell at the intersection of the column and row in which they appear. Interpolate as necessary.
