ISO 6619 - Acid Number
We perform testing by ISO 6619 to determine the acid number or acidic or basic constituents in petroleum products and lubricants. This method may be used to indicate relative changes that occur in an oil during use under oixidizing conditions regardless of the color of the resulting oil.
We also perform acidity and acid number testing by ASTM D1613, ASTM D3242, ASTM D664, ASTM D7795, ASTM D847, ASTM D974, IP 139, IP 177, IP 354, ISO 6618, 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.
