Designation: D 4739 02An American National StandardStandard Test Method forBase Number determination by potentiometric Titration1This Standard is issued under the fixed designation D 4739; 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 (e) indicates an editorial change since the last revision or Scope* This test Method covers a procedure for the determina-tion of basic constituents in petroleum products and lubricants(Note 1). The test Method resolves these constituents intogroups having weak- base and strong- base ionization proper-ties, provided the dissociation constants of the more stronglybasic compounds are at least 1000 times that of the next This test Method covers base numbers up to 70.
