From Introduction: "Following the guidelines established by this committee, several commercially developed precision connectors have appeared on the market which have led to the wide use of the precision coaxial lines as immittance standards. This paper has been prepared to alleviate this situation by providing graphs from which the electrical parameters of the lines may be determined rapidly and accurately."

Technical paper issued by the Bureau of Standards over studies conducted on the specifications of color. The specifications of the color yellow are discussed. This paper includes tables, illustrations, and photographs.
