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. 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 asm specimen in relation to another test specimen provides an effective tool for discrimination.

Results are reported as micrograms per millilitre ppm extracted relative to the internal volume of the glass article.
