Abstract: In GB10345.4-89 《Method for determination of total acid in Chinese spirits》, titration with the NaOH standardsolution, the total acid can be detemind. By the experiment of the uncertainty in measurement of acid evaluated, this paperexpounded a new method of evaluate uncertainty in measurement in analysis.

Key words: spirits, total acid, uncertainty in measurement, evaluate
