IBAMA may request clarifications or the revision of reports at any given time and at its discretion, as long as duly justifiable, and request the performance of tests that confirm prototype inspections and production conformity and select, randomly, samples of vehicles from the assembly line or from commercialization stocks for the performance of tests.
Single paragraph. IBAMA must be provided with the means necessary for the performance of tests according to the provisions set by article 2 of this Resolution including calibrated measurement tools and their accessories, test fields and vehicles for testing purposes.
Art. 11. IBAMA may, in cases where irregularities have been verified during prototype testing processes or related to production conformity by the responsible enterprise, issue a Commercialization Suspension Order for the respective vehicle configurations.
§ 1 The Commercialization Suspension Order implies immediate compliance with its provisions until the irregularities that originated it have been clarified and corrected.
§ 2 The re-initiation of vehicle commercialization can only start after full compliance with the provisions set by this Resolution.
Art. 12.
