ASTM C895

There are several test methods available to measure the lead and cadmium release from dinnerware and cookware (see Test Methods C 738 and C 1034 and Specification C 1035). These standards are used as a control to ensure the protection of the population against a possible health hazard. This potential hazard arises with improperly formulated, applied, fired glazes and decorations. This test method deals specifically with ceramic tile that are intended to come in contact with food during its preparation (for example, counter top tile).

1. Scope

1.1 This test method covers the precise determination of lead and cadmium extracted by acetic acid from glazed ceramic tile that are intended for use in areas of food preparation. 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 tile. This test method is specific for lead and cadmium.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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.
