Excerpt from Standard Reference Materials: Determination of Oxygen in Ferrous Materials Srm 1090, 1091, and 1092 Within the framework of the nbs Institute for Materials Research the area of standard reference materials is a broad and important one, including the preparation, characterize tion and distribution of a wide variety of materials in such diverse fields as metallurgy, polymers and inorganic materials. In carrying out such a program there is much interaction with representatives of industry and science beginning with discussions as to which primary standard materials will do most to advance technology, the furnishing of materials and fabrication of samples, and the characteri zation and certification of the materials by cooperative efforts. The many groups participating in a standards program are very interested in detailed information on specific aspects of the program but to date there has been no publication outlet for such written discussions. To meet this need, nbs Miscellaneous Publication 260 has been reserved for a series of papers in the general area of standard reference materials. This series will present the results of studies and investigations undertaken within the Institute for Materials Research with emphasis on the preparation and characterization of standard reference' materials. This subject-oriented series will probide a means for rapid dissemination of this detailed information and we hope will stimulate the use of standard reference materials in science and industry.
