The European Union Directives have the purpose of creating the necessary conditions so that the industries operating within the EU can realize products that comply with uniform requirements for the safety and health of citizens, the consumer protection and the defense of the environment, as required by the international Treaty of Rome, signed on 25 March 1957, that has established the European Economic Community. This article proposes to evolve the way of drawing up the standards relating to machinery, taking into account the metrological aspects, in order to conduct more objective risk analyzes. The greater reliability that can be achieved, can translate into a competitive advantage for the manufacturers of the machinery themselves.

Keywords: Metrology, Safety, Risk, Machine, Directive, Standard.
