Standard Test Method for Analysis of Heavy Metals in Glass by Field Portable X-Ray Fluorescence (XRF)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers field portable X-ray fluorescence (XRF) spectrometric procedures for analyses of arsenic and lead in glass compositions using field portable energy dispersive XRF spectrometers.
1.2 The mass fraction range of arsenic within which this test method is quantitative is given in Table 1. Scope limits were determined from the interlaboratory study results using the approach given in Practice E1601.
1.3 The mass fraction range for which lead was tested is given in Table 1. However, lead results cannot be considered quantitative on the basis of single-sample results because the precision performance is not good enough to allow laboratories to compare results in a quantitative manner.
1.3.1 To obtain quantitative performance, lead results must consist of the average of four or more determinations.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. Some specific hazards statements are given in Section 7 on Hazards.
Significance and Use
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.
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.
5.5 Detection limits, sensitivity, and element ranges will vary with matrices, detector type, and other instrument conditions and parameters.
5.6 All analytes are determined as the element and reported as such. These include all elements listed in Table 1. This test method may be applicable to other glass matrices, additional elements, and wider concentration ranges provided the laboratory is able to validate the broadened scope of this test method.
