The quality of springs, as machine elements, is important to maintain and improve the high quality of Japanese industrial products. These days, dissemination of personal computer makes it easy to evaluate the design of springs when all the fact data (tested values) are provided. The characteristic values of various materials, as a result of research and investigation, are being reported in technical papers issued every year in Japan and overseas. If these values are used for the fact data, we anticipate that the database for spring material becomes useful and covers a widespread area. Therefore, the committee has been working to collect data and to turn them into a database for the benefit of general spring designers. We picked up the data of JIS (Japanese Industrial Standards) materials from a total of 878 technical papers, read off the figures from the diagrams of main characteristics, and then tried to unify the data from multiple papers. Through this work, we found lots of variations in the data due to the differences of testing and sample making conditions. We also found lots of papers without the reference of testing and sample making conditions. The importance of the testing and sample making conditions to be described in all technical papers should be deeply engraved in researchers' mind. Finally, we hope that the data mapping tables made through this activity will be used as a reference database for finding the whereabouts of material characteristics and technical papers which contain them.
