摘要:Author Jean-Claude André Institut national de recherche et de sécurité (INRS), Avenue de Bourgogne, 54500 Vandoeuvre 30, rue Olivier Noyer 75014 Paris Key words: ethics, nanotechnology, norm Page(s) : 411-5 Published in: 2005 Norms make it possible to define a framework for innovation and then to guarantee some aspects of industrial performance. Progress requires the use of the scientific knowledge and techniques then available, and the period revisiting of their contents. The preparation of new norms appears desirable for new technologies, to the extent that they can be supported by an adequate foundation of scientific knowledge. The author raises questions about our fragmentary and still uncertain knowledge in the realm of nanotechnologies and he considers it useful to envisage “normalization” in a new framework – at least for him – the “precautionary normalization.”
