This test method details the standard and precise procedures for the determination of lead and cadmium extracted by acetic acid from glazed ceramic surfaces. The apparatus needed for this procedure include an atomic absorption spectrometer, lead and cadmium lamps, and glassware of chemical resistant borosilicate glass. The water, detergent wash, and reagents such as acetic acid, lead nitrate solution, hydrochloric acid, and cadmium solution should conform to chemical purity specified. Measurement procedures, precision, and bias are discussed thoroughly.
