适用范围

5.1 Waste glass is currently recycled into various consumer products. This test method has been developed as a tool for evaluation of heavy metals in glass to satisfy reporting requirements for maximum allowable content for some applications.

5.2 The ranges within which this test method is quantitative are given in Table 1.

5.3 For amounts of the analyte elements outside the ranges in Table 1, this test method provides screening results. That is, it provides an unambiguous indication that each element can be described as present in an amount greater than the scope upper limit or that the amount of the element can be described as less than the scope lower limit with a high degree of confidence.

Note 2In general, when a quantitative result is obtained, the analyst can make a clear decision as to whether a material is suitable for the intended purpose. When the contents of elements of interest are outside the quantitative range, the analyst can still make a decision whether the amount is too high or whether additional analyses are required.

5.4 These methods can be applied to glass beads, plate glass, float glass, fiber glass, or ground glass. This test method has been validated for the ranges of matrix compositions that are summarized in Table 2.
