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.
It is, therefore, important to measure the amount that may be extracted from c972 area of the glass drinking vessel in contact with the lip.
