Total Acid Number (TAN) Measurement for Oil Samples
Total Acid Number or TAN is a measure of both the weak organic and strong inorganic acids present within oil.
Testing for TAN is essential to maintain and protect your equipment, preventing damage in advance. A rise in TAN is indicative of oil oxidation due to time and/or operating temperature. Trend as well as absolute values should be used to monitor TAN levels.
High operating temperatures severely stress the oil. This results in oxidation and nitration, changes in viscosity, the build up of acidic waste products and deposits on metal surfaces. TAN is generally an issue in gearbox lubricants , gas engine , gas turbine and hydraulic lubricants . It is not generally associated with engine crankcase lubricants unless they are severly contaminated.
The singular exception may be crankcase lubricants for gas engines, where TBN can deplete very rapidly and elevated operating temperatures can generate high leves of weak organic acids.
Kittiwake supply various types of test for TAN, depending on your requirements. Equipment includes the following:
TAN Test Kit - Electronic Cell (FG-K25196-KW)
The TAN Cell works in conjunction with a highly accurate electronic console, included as part of the Oil Test Centre .
The TAN test is available as a stand-alone kit, or as part of a comprehensive suite of electronic equipment including cells to test for TBN, Water in Oil and Insolubles.
Range: 0 - 3 /0-6 KOH / g TAN
Test Time: 2 mins
Accuracy: Typically within +/- 0.2 TAN
Power: 110 to 250 VAC
Correlation: IP177 (ASTM D974), SAE ARP 5088 (modified IP139, ASTM D974)
Application: Gas or Steam Turbine Oils, Hydraulic, Aviation & Gearbox Lubricants
Optional software is available that allows the test data to be downloaded from the console to a PC in comma delimited text format. This means that the data stream is separated by commas and is in a standard ASCII format that is readable by standard spreadsheet and data base applications, such as Microsoft Excel and Access.
