摘要： PURPOSE:To decide whether production is possible or not by determining the analogous standards to satisfy the prescribed conditions for the information on the new product specifications to be decided, determining at least a part of the conditions for the material tests of the specification information included therein according to the contents of the above- mentioned information on the new product specifications and the contents of the above- mentioned analogous standards and contrasting the resulted final specification information with the information on the past results. CONSTITUTION:Whether the production is possible or not is basically decided by utilizing the actual data on the past ample standard products in this invention. Namely, the standards analogous with the new standards are selected and the product specifications necessary for the decision are determined on the basis of the specification data relating to the selected analogous standards. However, if the conditions of the specific material quality tests of the analogous standards and the new standards vary, the specifications of the analogous standards are adopted in place of the new standards as the product specifications for the decision of this part. Decision is made that the production is possible if the production record of the material quality level stricter than the product specifications to be decided exists for the past results of the conditions on the material quality tests equal to the conditions for the material quality tests for the product specifications determined in such a manner.
