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.
Element
Scope Lower Limit (mg/kg)
Scope Upper Limit (mg/kg)
Arsenic

2000
Lead
120
500
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.
