Abstract

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.

Scope

1.1 This test method covers the precise determination of lead and cadmium extracted by acetic acid from glazed ceramic surfaces. The procedure of extraction may be expected to accelerate the release of lead from the glaze and to serve, therefore, as a severe test that is unlikely to be matched under the actual conditions of usage of such ceramic ware. This test method is specific for lead and cadmium.

1.2 The values stated in SI (metric) units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
