D4326 - Standard Test Method for Major and Minor Elements in Coal and Coke Ash By X-Ray Fluorescence

Three (3) interlaboratory studies have been carried out for D4326 in the years 1984 (RR D05:1006), 1989 (no research report), and 1995 (no research report). The precision data on file in RR D05:1006 was not sufficiently supportive. In 2021 the task group undertook the project to review the data on file for all 3 ILS’s. That project included: revalidation of lab-submitted data; review of sample preparation and homogeneity information; review of material types; and statistical treatment.
