ASTM C – 87() Standard Test Method for Lead and Cadmium Extracted from Glazed Ceramic Tile
Search book title Enter keywords for book title search. Stir the sample leaching solution and pour off a portion into a clean? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Precision and Bias This standard does not purport to address all of the safety concerns associated with its use. Use the operating conditions as speci? 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 standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Remove c97 article after the h leaching period and determine the lead and cadmium by atomic absorption. This test method is specific for lead and cadmium. This test method is speci?

These standards are used as a control to ensure the protection of the population against a possible health hazard. The procedure of extraction may c92 expected to accelerate the release of lead and cadmium from the decorated area and to serve, therefore, as a severe test that is sstm to be matched under the actual conditions of usage of such glassware. Commercially available standard lead solutions may also be used. Cover the glassware containers, if possible, to prevent evaporation and to protect them from contamination.
Record the internal volume of each article in millilitres by? Bracket the sample solution with the next higher and lower working solutions. Determine lead from a standard curve of absorbance against? 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. In this test method, the detection limit shall be de?

Therefore, in this instance microgram per millilitre equals microgram per gram which equals parts per million. ICS Number Code The values given in parentheses are for information only. No other units of measurement are included in this standard.
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. 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.
Copyright Compu-tecture, Inc. Dilute samples containing more than 20? It is, therefore, important astn measure the amount that may be extracted from an area of the glass drinking vessel in contact with the lip.
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.
Are you sure you want to empty the cart? Invert the article in an appropriate laboratory glassware container whose diameter is a minimum of 1. If it is, sufficient acetic acid solution should be added to restore the leaching solution to the mm mark. Then rinse with tap water followed by distilled x927 followed by air drying.
