Beschreibung
Zusammenfassung:	FIELD: analytical methods. ^ SUBSTANCE: invention is intended for use as a means of metrologically supporting measurement techniques in determination of total alkaline number of motor oils and lubricating materials. This means is represented by composition containing 75-84% liquid hydrocarbons, 0.05-6% water-soluble alkali component, and 15-20% aliphatic alcohol. Use of standard specimen allows performing reliable estimation of quality of motor oils and lubricating materials by accessible acid-base titration technique requiring no special instrumentation equipment. ^ EFFECT: simplified analytical procedure. ^ 1 tbl
