This standard is issued under the fixed designation D633; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope
1.1 This table (Table 1) has been prepared by the National
Institute of Standards and Technology to meet a demand from
the tar industry for a short and convenient table for reducing
volumes of road tar to the basis of 60°F (15.6°C) when extreme
accuracy is not required. The table shows the volume occupied
at 60°F (15.6°C) by a quantity of material occupying unit
volume at the indicated temperature.
1.2 Units—The values stated in inch-pound units are to be
regarded as the standard. The values given in

2.1 ASTM Standards:
D490 Specification for Road Tar
3. Significance and Use
3.1 Tars change in volume with changes in temperature.
They are loaded or transferred at widely varying temperatures.
Volume correction factors are used to adjust bulk volumes
measured at those temperatures with corresponding volumes at
a base temperature of either 60°F or 15.6°C for the purposes of
custody transfer and accounting operations.
3.2 Correction factors as provided in this table have proven
to be sufficiently accurate for the intended purposes.
3.3 The coefficient of expansion for D490 Type RT-12 at
60°F (15.6°C) per degree F is 0.00030.
