L'ISO 3771:2011 spécifie une méthode permettant de déterminer les constituants basiques dans les produits pétroliers, par titrage potentiométrique au moyen d'acide perchlorique dans de l'acide acétique glacial.
Les constituants qui peuvent être considérés comme ayant des propriétés basiques comprennent les bases organiques et inorganiques, les composés aminés, les sels d'acides faibles (par exemple les savons), les sels basiques de bases polyacides et les sels de métaux lourds.
Les plages de valeurs des indices de base pour lesquelles les valeurs de fidélité de la méthode ont été établies sont: huiles fraiches, avec un indice de base allant de 3 à 45; concentrats d'additifs, avec un indice de base allant de 5 à 45; et huiles usagées, avec un indice de base allant de 3 à 30.
