Description of ASTM-F2980 2013ASTM F2980-13Historical Standard: Standard Test Method for Analysis of Heavy Metals in Glass by Field Portable X-Ray Fluorescence (XRF)ASTM F2980Scope 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.
Note 1—The performance of this test method was evaluated using results based on single-sample determinations from
specimens composed of glass beads. One laboratory has determined that performance can be significantly improved by basing reported results on the mean of determinations from multiple samples
to overcome inherent heterogeneity of elements in glass beads, especially the element lead. Additional information is provided in Section 17 on
Precision and Bias.
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.
