ISO 6618 - Acid Number - Color-Indicator Titration
We perform testing by ISO 6618 to determine the acidic or basic constituents in petroleum products and lubricants using a color-indicator titration. This method is applicable for products that have extremely low dissociation constants.
We also perform acidity and acid number testing by ASTM D1613, ASTM D3242, ASTM D3339, ASTM D664, ASTM D7795, ASTM D847, ASTM D974, IP 139, IP 177, IP 354, 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.
