This document constitutes an adaptation of standardized access to RMI prescriptions for passenger cars to L-category vehicles keeping the objectives and principles of the mandate M/421 from the European commission. ISO 18541-6:2018 references the usage of a Digital Annex of standardized search terms for RMI. The provision of such a Digital Annex will follow the process described in ISO 18542. CEN will nominate a Registration Authority according to ISO 18542 for the creation and maintenance of an appropriate Digital Annex.
