Book excerpt: Excerpt from Circular of the Bureau of Standards, 1918, Vol. 73: Copper The endeavor in the circulars, therefore, is to reproduce only such data as have passed critical scrutiny, and to suitably qualify in the sense outlined above all statements, numerical or otherwise, made relative to the characteristics of the metal. This circular is the first one issued on the metals; 1 copper has been chosen for the reason that much of the accurate information regarding copper has been obtained at this Bureau, and that, in general, our knowledge of the properties of this metal is more complete than of any other. Furthermore, commercial copper has a very high degree of purity. The data and information have been put in the form of tables and curves; the curves have been reproduced in such dimensions that accurate interpolation of values on them is possible by the use of a rule graduated in decimal parts of a centimeter. The probable degree of accuracy of data is indicated, or implied, by the number of significant figures in the values given.
