PANEL DISCUSSION: METRIC CONVERSION PROBLEMS AND SOLUTIONS

The main problems on which this discussion focused were related to standardization, the publication of handbooks, the role of professional associations and industrial organizations, and governmental action. The distinction is made between the problems of standardization and metric conversion and the impetus towards standardization produced by metrication is discussed. Dimensional standardization and misunderstandings in this area are noted. Metric conversion involves hard conversion and soft conversion (language change). Comments are made related to the language change and the loss of mental standards. The system of training at General Motors is recommended, and the publication of dually dimensioned handbooks is discussed. The inadequacy of many handbooks is noted. The ASTM E-380-72 is recommended as a good publication. The question was also discussed of how the production of handbooks and the conversion by suppliers is affected by national legislation on metrication. It is noted that metrication has produced a catalyst for standardization in the tunneling and construction industries. Emphasis is placed on international standardization. British experience in the tunneling industry is quoted in answering questions regarding what must be converted first, the sequence to be adopted, and the length of time involved. The multiplicity of local standards in the construction trades and the problems posed by local building codes were also discussed. The need is indicated for federal government backing of a metric conversion program. National scientific and professional organizations are urged to get the message across to their members and their representatives in the legislature.
