The timely development of harmonised standards during the transitional period for the application of this Regulation and their availability before the date of application of this Regulation will be particularly important for its effective implementation. This is, in particular, the case for important products with digital elements that fall under class I. The availability of harmonised standards will enable manufacturers of such products to perform the conformity assessments via the internal control procedure and can therefore avoid bottlenecks and delays in the activities of conformity assessment bodies.
