(Abstract is updated on 15th of February 2013 upon the request of the author) Long-term data sets might affect the significance of economical and statistical applications. However, revisions in the International Standard Industrial Classification (ISIC) system may prevent to get long-term data sets. In other words, due to different classification systems which aren’t associated with each other, the industrial data sets cannot be used efficiently. This study presents a proposal to solve this problem. By using eight- and nine-digit data in Revision-2 and Revision-3 systems the four-digit transformation ratios are calculated. By using the ratios calculated, a data set that is classified according to revision-2 (revision-3) could be transformed into revision-3 (revision-2). If you have the manufacturing data sets which are classified by revision 2 or revision 3, you can transform it to revision 3 or revision 2 by using transformation ratios which are presented by me. The ratios were calculated using Turkish data sets.
