This instrument should have a sensitivity of about 0. No other units of measurement are included in this standard. Remember me for one month. Record the lead and cadmium found in micrograms per millilitre. Copyright Compu-tecture, Inc.
Flush the burner with water and check zero point between readings. The analyst should determine whether the acetic acid leaching is noticeably below the mm mark before removing the article. Significance and Use The heavy metals, lead and cadmium, are known to cause serious health effects in man if consumed in excess.
Stir the sample leaching solution and pour off a portion into a clean? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Invert the article in an appropriate laboratory glassware container whose diameter is a minimum of 1. 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. Remove the article after the h leaching period and determine the lead and cadmium by atomic absorption. ICS Number Code This standard does not purport to address all of the safety concerns associated with its use.
Are you sure you want to empty the cart? Historical Version s – view previous versions of standard. Results are reported as micrograms per millilitre ppm extracted relative to the internal volume of the glass article.
Precision and Bias No items in cart. Record the volume of solution used. Representative detection limits would be approximately 0. In this test method, the detection limit shall be de?

Mark each unit 7 mm below the rim. NOTE 4—The internal volume of the article expressed in millilitres of water closely approximates its weight in grams. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
This standard does not purport to address all of the safety concerns associated with its use. 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.

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. 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.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Note 1 — For additional information see Test Method C It is, therefore, important to measure the amount that may be extracted from an area of the glass drinking vessel in contact with the lip. Then rinse with tap water followed by distilled water followed by air drying.
