ASTM C872-89(2005)

1.1 This test method covers the precise determination of lead and cadmium extracted by acetic acid from porcelain enamel surfaces.

1.2 Values stated in SI units are to be regarded as the standard. Inch-pound units are given 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.

The determination of lead and cadmium release from porcelain enamel surfaces was formerly of interest only to manufacturers of porcelain enamel cookware and similar food service products. Food contact surfaces of these container-type products have been evaluated using a test procedure similar to Test Method C 738. Recently, however, there has been a need to measure lead and cadmium release from flat or curved porcelain enamel surfaces that are not capable of being evaluated by a test similar to Test Method C 738.
