IP 139 - Acid or Base Number by Color Indicatior Titration
We perform lubricants quality testing by IP 139 to determine the acidic or basic constituents (acid or base number) in petroleum products and lubricants. New and used petroleum products can contain basic or acidic constituents that are present as additives or as degradation products formed during service, such as oxidation products. The relative amount of these materials can be determined by titrating with acids or bases. This number, whether expressed as acid number or base number, is a measure of this amount of acidic or basic substances in the oil, always under the conditions of the test. This number is used as a guide in the quality control of lubricating oil formulations. It is also sometimes used as a measure of lubricant degradation in service.
We also perform acidity and acid number testing by ASTM D1613, ASTM D3242, ASTM D3339, ASTM D664, ASTM D7795, ASTM D847, ASTM D974, IP 177, IP 354, ISO 6618, ISO 6619, and SAE ARP5088. These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
