【国外标准】 Standard Test Method for Lead and Cadmium Extracted From Glazed Ceramic Cookware (Withdrawn 2001)

1.1 This test method covers the precise determination of lead and cadmium extracted by acetic acid from glazed ceramic surfaces under boiling conditions. The procedure of extraction may be expected to accelerate the release of lead and cadmium from the glaze and to serve, therefore, as a severe test that simulates the most severe conditions of usage of such ceramic cookware. This method is specific for lead and cadmium. 1.2 This test method is applicable to ceramic cookware intended for use in contact with food, for example cookware made of china, crockery, porcelain, and earthenware. 1.3 This standard does not purport to address 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.
