Detailed structure and explanatory notes

ISIC Rev.3 code 73


  • Tabulation Category: K - Real estate, renting and business activities
  • Division: 73 - Research and development


This Division is divided into the following Groups:

  • 731 - Research and experimental development on natural sciences and engineering (NSE)
  • 732 - Research and experimental development on social sciences and humanities (SSH)

Explanatory note

This division includes the performance of the following three types of activities:
- Basic research, experimental or theoretical work undertaken primarily to acquire new knowledge of the underlying foundations of phenomena and observable facts, without particular application or use in view.
- Applied research is also original investigation undertaken in order to acquire new knowledge. It is, however, directed primarily towards a specific practical aim or objective.
- Experimental development is systematic work, drawing on existing knowledge gained from research and/or practical experience, that is directed to producing new materials, products and devices, to installing new processes, systems and services, and to improving those already produced or installed.
The basic criterion for distinguishing R&D from related activities is the presence in R&D of an appreciable element of novelty.

Exclusions: Governmental administration of R&D and of associated funds in the various natural or social sciences are classified in the appropriate class of division 75 (Public administration and defence; compulsory social security).
Administration and support of defence related applied research and experimental development are classified in class 7522 (Defence activities).
Education combined with R&D is classified in the appropriate class of division 80 (Education).
The raising and management of R&D funds for medical and other social-related R&D by charities is classified in class 8532 (Social work without accommodation).
