TOTAL ACID NUMBER (TAN)

Acid Standards Base Number

Our ISO 17025 and ISO 17034 Total Acid Number (TAN) Standards are ideal for verifying analytical instruments which are used to determine acid number by potentiometric titration. Important as a confirmatory test in quality control testing of new lubricants, it can also be used for condition monitoring of in use or used lubricants. The TAN indicates the age of a lubricant, assisting on the timing of oil changes. They can be used for Lubricants, Condition Monitoring, Crude Oil and Biodiesel.
