Provides users of the API Manual of Petroleum Measurement Standards Chapter 11.1, Volume III (Table 6C) and Volume IX (Table 54C) with revised volume correction factor tables for MTBE. The tables can be used to expedite calculation of the volume of mixtures composed predominantly of MTBE at standard conditions from volumes at other conditions. These tables apply to commercially available mixtures containing at least 85 weight percent MTBE. The information gained from using these tables can be used to determine quantities of MTBE in tanks, shipping containers, and other storage containers typically used in the petroleum industry. Table 6C-Volume Correction Factors for Individual and Special Applications, Volume Correction for MTBE to 60*F and Volume IX, Table 54C-Volume Correction for Individual and Special Applications, Volume Correction for MTBE to 15*C.
