Proposal to explain para. 8.3.3.1. of the draft UN Regulation. The proposal addresses residual comments concerning wording used to derive scenarios for confirmatory testing by removing terminology not used in the regulation to avoid mis-interpretations. Confirmatory testing scenarios depend on the ADS feature, its ODD, and safety case scenarios. When selecting scenarios, the assessor may consider the ADS system description and its safety concept, and the safety claims presented in the safety case. Confirmatory testing may be undertaken using virtual testing, expected to be within the scope and capability of the toolchain being used, and can be within, at the boundary of or outside the ODD.
