Test kit for determination of acetic acid in artificial vinegar which consisted of two test solutions and syringes was tested for its efficiency, accuracy and precision. In the efficiency test, it was found that when the acid concentrations were between 3.90-4.10 and 6.90-7.10 percent which were near the lower and upper limit according to the regulation, the results were 50 percent accurate while at the other concentrations, they were 100 percent accurate. It was also found that the results were not different from the standard method. In the precision test which performed by 3 analysts also has no statistically differences. Therefore this test kit can be efficiently used either by small scale vinegar manufacturers or in field test purposes, because of its simplicity, high accuracy and precision.
