Description
The Acid Number refers to the quantity of base (expressed as mg KOH/g sample) required to titrate a sample to a well defined inflection point, as specified in ASTM D664. AN standards are manufactured, tested and certified in accordance with ASTM D664/IP 177 (by potentiometric titration) or ASTM D974 (by color-indicator titration). Verify system functionality, assure accuracy of your laboratory instrumentation and save time with our AN reference standards.
