This is kind of interesting, though I mostly put it here to link to it on twitter. It's from Appendix C of the UK's 2014 Research Excellence Framework instruction document.
1. For the purposes of the REF, research is defined as a process of investigation leading to new insights, effectively shared.
2. It includes work of direct relevance to the needs of commerce, industry, and to the public and voluntary sectors; scholarship, the invention and generation of ideas, images, performances, artefacts including design, where these lead to new or substantially improved insights; and the use of existing knowledge in experimental development to produce new or substantially improved materials, devices, products and processes, including design and construction. It excludes routine testing and routine analysis of materials, components and processes such as for the maintenance of national standards, as distinct from the development of new analytical techniques. It also excludes the development of teaching materials that do not embody original research.
