Med henblik på at bestemme det normale driftsniveau sammenlignes kontrollen af køretøjsystemets ydelse i normaltilstand med fabrikantens grundlæggende benchmarkspecifikationer, medmindre der skal foretages en nærmere angivet prøve af bremsevirkning i henhold til godkendelsesproceduren i dette eller et andet regulativ.
As the means of establishing the normal operational levels, verification of the performance of the vehicle system under non-fault conditions shall be conducted against the manufacturer's basic benchmark specification unless this is subject to a specified performance test as part of the approval procedure of this or another Regulation.
