The classification provides a framework for the collection, tabulation, presentation and analysis of data, and its use promotes uniformity.
In addition, it can be used for administrative purposes and by non-government bodies as a convenient way of classifying industrial activities into a common structure.
Since 1948 the classification has been revised in 1958, 1968, 1980, 1992, 1997, and 2003.
