The work of the former Committee on Standardization of Tests is the starting point for the work covered in this paper. The action of citric acid on different types of enamels is studied. The time required to produce first etching of cooking ware enamels with 15% acid is investigated. The above lead to the conclusion that commercial cooking ware enamels as a whole are readily etched by 15% citric acid and the degree of etching is not necessarily proportional to the time of action. The use of 1% acetic acid and also the use of a “spot” test are investigated, including tests on commercial ware. The work as a whole brings out certain weaknesses of the possible methods of testing but does not result in the establishment of a satisfactory test.
