The repeatability (within a single lab) for total amine value is approximately ±1-2% relative standard deviation (RSD). Reproducibility (between labs) is higher, around ±3-5% RSD. (typically bromocresol green or methyl orange) to identify

Total Base Number measures the alkalinity of an oil. In lubricants (especially engine oils), TBN indicates the ability to neutralize acids formed during combustion. A high TBN means the oil has significant reserve alkalinity to fight corrosion and sludge.

Finding the right solvent ratio to dissolve dark, heavy oil without causing phase separation is tricky. The ASTM D2074 provides specific guidance on troubleshooting turbidity.
