Precision and Bias Mark each article, in a nondecorated area if possible20 mm below the rim on the outside. Invert the article in an appropriate laboratory glassware container whose diameter is a minimum of 1. Determine lead from a standard curve of absorbance against? Therefore, in this instance microgram per millilitre equals microgram per gram which equals parts per million. 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.

Current edition approved Oct. This test method is specific for lead and cadmium. A superscript epsilon e indicates an editorial change since wstm last revision or reapproval. This test method is specific for lead and cadmium. The procedure of extraction may be expected to accelerate the release of lead and cadmium from the decorated area and to serve, therefore, as a severe test that is unlikely to be matched under the actual conditions of usage of such glassware.
This standard does not purport to address all of the safety concerns associated with its use. Register for a trial account. 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.

Mark each unit 7 mm below the rim.
If it is, sufficient acetic acid solution should be added to restore the leaching solution to the mm mark. Analyze each new batch of reagents for lead and cadmium. Cover the glassware containers, if possible, to prevent evaporation and to protect them from contamination. Record the lead and cadmium found in micrograms per millilitre.

ASTM C – 87() Standard Test Method for Lead and Cadmium Extracted from Glazed Ceramic Tile
Significance and Use The heavy metals, lead and cadmium, are known to cause serious health effects in man if consumed in excess. Commercially available standard lead solutions may also be used. Even though the amount of lead and cadmium extracted by this test method is in no way representative of the amount of the metals extracted by actual lip contact, the relative magnitude of metals extracted from one test specimen in relation to another test specimen provides an effective tool for discrimination.
The heavy metals, lead and cadmium, are known to cause serious health effects in man if consumed in excess.
The analyst should determine whether the acetic acid leaching is noticeably below the mm mark before removing the article.
