Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references (p. 6). "Three low-grade tungsten ores, two of scheelite (CT-1 and TLG-1) and one of wolframite (BH-1), have been characterized and prepared for use as certified reference materials. This report is a detailed account of the inter-laboratory program for obtaining the analytical results for tungsten, and the statistical treatment used to assign the recommended values, which are 1.04%, 0.42% and 0.083%, respectively, for CT-1, BIT-1 and TLG-1. Information is also given on the nature and origin of the three ores, and on the procedures used for their preparation and for assessing their homogeneity"--Synopsis, p. i.
