Compliant with ASTM D2896 and IP 276 methods.
Applications
FAQ
TBN indicates the acid-neutralizing capacity of engine oil. A drop below a certain threshold signals that the oil needs to be changed.
No. Choose two or three reference points for your application: low, mid, and high range. This is sufficient for regular calibration.
D2896 uses perchloric acid titration; IP 276 uses HCl titration. CONOSTAN standards are compliant with both.
Yes. Both series can be sourced in a single order through Anka Analitik.
