4104 - Testing and approval of equipment.

     § 4104.  Testing and approval of equipment.        (a)  Authority of department.--The department may require new     vehicles and equipment to be tested and approved for compliance     with the requirements of this part or any vehicle equipment     standard adopted pursuant to section 4103(a) (relating to     promulgation of vehicle equipment standards).        (b)  Basis of approval.--Approvals may be based on     certification furnished to the department by the American     Association of Motor Vehicle Administrators, or if the American     Association of Motor Vehicle Administrators certification     program does not cover the type of vehicle or equipment, the     department shall determine approval on test reports prepared by     such testing laboratories as the department may designate.        (c)  Procedure for approval.--The department shall establish     by regulation the procedure to be followed when request for     approval of any item of equipment is submitted under this     section. The department shall not unreasonably withhold     designation of any laboratory which meets the minimum criteria     established by the department as an approved laboratory for     equipment testing. Where a regulated manufacturer has its own     in-house testing facilities which meet the minimum criteria, the     department may accept test reports from the manufacturer for the     purpose of granting equipment approvals.        (d)  Markings on approved equipment.--Each item of equipment     requiring approval by the department shall bear the trademark,     name or code symbol under which it is approved. If practicable,     the markings shall be legible after installation. For the     purposes of this subsection, code symbol means one assigned and     approved by the department in the absence of a name or     trademark.        (e)  Lists of approved equipment.--The department shall     maintain lists of all items of equipment which have been     approved under authority of this part. Copies of the lists or     portions of the lists shall be made available at cost upon     request.        Cross References.  Section 4104 is referred to in section     1954 of this title.
