Total Acid Number Standards & Reagents
Total Acid Number Standard: 1.0 mg/g KOH

Mean Measured Value:1.000 mg/g KOH
Specification:0.900- 1.100 mg/g KOH
Method of Analysis:Potentiometric titration in accordance with ASTM D664, Method A (inflection end-point).

Metrological Traceability:

The result reported above was determined by analysis of a sample of this lot taken at time of manufacture. Test Method used was TP-TAN. This solution was checked by means of Analytical Volumetric Standard Potassium Hydroxide in Propanol-2-ol. It is directly traceable to NIST (USA), 84L Potassium Hydrogen Phthalate. All raw materials used to prepare this product are of high purity. The uncertainty of measurement has been calculated not to exceed ± 2.0% at 95% confidence level, i.e. coverage factor k =2.
