Abstract

Zusammenfassung Case studies in the history of science and technology have shown that scientific norms, so called standards, contribute significantly to the evolution of scientific practices. They arise predominantly, but not exclusively, on the basis of interactions with instruments of measurement and other technical devices. As regards experimental practices standards are mandatory preparatory procedures in a variety of designs, including the inbreeding and genetic engineering of experimental organisms (e.g. transgenic mice). I claim that scientific norms not only regulate mere technical preconditions of research but also guide experimental practices, for example with regard to the stabilisation and validation of phenomena. Against this background, the paper introduces different kinds of scientific norms and elaborates on the question if they are means to epistemic ends (e.g. stability).
