The text discusses a normative field, albeit little studied, with a relevant practical dimension in contract law, competition law, as well as in the field of civil liability, namely standardisation. We will therefore analyse the main aspects of standardisation at its current stage, its objectives, the types of standards, the actors and agents, the problems and its evolution. In a liberalised economy, standardisation aims to make traded products and services compatible. The possibility of standardising healthcare services has provoked vehement protests from various healthcare professionals, especially in European countries with stronger economies.
