The SIC Code is used to classify industries; the Defense Technical Information Center (DTIC) schedule is used to classify areas of technology of interest to the DoD; the Library of Congress classification schedule of books also addresses Technology (Class T) and Science (Class Q). These, and other classification schemes are almost mutually exclusive, in that they address either industry or science and technology, but not both.
Moreover,
This classification schedule is limited to Hi-Tech and it does not cover all general traditional industries; It covers (i) engineering sciences, and (ii) life sciences and medical technology.
The TechExpo Classification Schedule attempts to maintain a cross reference to:
