摘要

This report covers the progress made in the collection of reference samples, and describes the completion of the five interlaboratory analytical programmes (those on ferrochromium slags, fluorspar, 'mixed' NIMROC samples, rare earths, and ferromanganese slags). A comprehensive tabulation of the samples that have been evaluated, and a list of the samples that have not been evaluated are included. (Atomindex citation 15:023972)
