The following chapter gives an overview about standardization in general, its processes and products. It also describes how standardization can support innovation and can be used in research projects, like CIRC-UITS. As an excerpt from the standardization landscape for CIRC-UITS, existing standards, ongoing standardization projects, as well as relevant standardization committees (technical committees) are presented in the context of the automotive and the electronics sector under consideration of circular economy and environmental aspects. The needs and gaps in standardization identified by the CIRC-UITS project are listed and ideas for filling these gaps are explained. The need for standardization in relation to activities regarding the digital product passport (DPP), the repairability and the assessment of repairability of products, as well as the need for standardization considering circular economy approaches in the field of rare earth were identified. Standardization can support the dissemination and exploitation of project results and thus the implementation of project innovations on the market through standardization activities, e.g. by contributing to ongoing standardization projects at national, European or international level or by developing new standardization documents. Various standardization activities have been performed in order to close different gaps in the standardization field. Project results dealing with a DPP of printed circuit boards and the aspect of the improvement/assessment of a product repairability, are planned to transfer to standardization through the development of two standardization documents. First standardization activities have been initiated. The description of planned and conducted standardization activities within CIRC-UITS completes the chapter on standardization.
