As a part of the Refractory Metals Sheet Rolling Program, reference materials unalloyed W, T-111 Ta, FS-85 Cb, and TZM Mo were prepared and analyzed by 25 cooperating laboratories. No serious problems were encountered in determining alloying elements. Hydrogen and carbon determinations could be made satisfactorily at the levels encountered, but agreement on oxygen and nitrogen was not satisfactory below the 10 ppm level. Recommendations for research to solve remaining problems are offered.
