Abstract : Science and technology use a large variety of symbols to represent physical properties, chemical formulas and mathematical expressions. Data centers that codify and evaluate physical properties need to use this conventional symbolism in their work. It is recommended that these data centers adopt the symbols and terminology specified by the various International Unions both in manual operations and in the creation of machine-readable data bases. It is demonstrated that these conventional symbols can be produced by modern communications devices that are compatible with the international standard codes for information interchange. A set of characters suitable for representing scientific data and text is presented and proposed as an extension of the ISO information interchange code. The use of this extended character code by computer oriented data centers at the National Bureau of Standards is described. The equipment needed for this level of performance and criteria for their selection are outlined. (Author)
