Designation: D1298 12bManual of Petroleum Measurement Standards (MPMS), Chapter Test Method forDensity, Relative Density, or API Gravity of Crude Petroleumand Liquid Petroleum Products by Hydrometer Method1This Standard is issued under the fixed designation D1298; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon ( ) indicates an editorial change since the last revision or Scope* This test Method covers the laboratory determinationusing a glass hydrometer in conjunction with a series ofcalculations, of the density, Relative density, or API gravity ofcrude petroleum, petroleum products, or mixtures of petroleumand nonpetroleum products normally handled as liquids, andhaving a Reid vapor pressure of kPa ( psi) orless. Values are determined at existing temperatures andcorrected to 15 C or 60 F by means of a series of calculationsand international Standard The initial hydrometer readings obtained are uncor-rected hydrometer readings and not density are measured on a hydrometer at either the referencetemperature or at another convenient temperature, and readingsare corrected for the meniscus effect, the thermal glass expan-sion effect, alternate calibration temper
