Research Report RR:F40-1002
Interlaboratory Study 609 (originally ILS 208) was conducted in two parts. The first activity was to obtain quantitative results for six glass bead materials to enable the task group to assign reference values using test methods independent of the X-ray fluorescence (XRF) method under development. With reference values, a bias statement can be included in the new standard. The second activity of ILS 609 was conducted to establish a precision and bias statement for the XRF results used to validate F2980 Test Method for Analysis of Heavy Metals in Glass by Field Portable X-Ray Fluorescence.
