Dear Mr. Knapp: This letter confirms the discussion which took place during your visi to the Bureau on September 18, between yourself and Mr. Risteen of my staff, concerning the requirements of Federal Motor Vehicle Safety Standard No. 206 as related to aftermarket door lock installations.; Since Standard No. 206 does not apply to aftermarket installations, yo may continue to sell your special locking arrangement to State Police and private individuals without violating that Standard. It is suggested, however, that you check your State auto inspection laws to make sure there is no conflict with State regulations.; In response to your request, Mr. Risteen reviewed the test repor contained in your Automotive Safety Door Lock brochure. According to the report, the longitudinal and transverse loads which your locking assembly withstood were considerably higher than that required by Standard No. 206. However, the testing company did not certify that your locking device met the requirements of this Standard.; Sincerely, George C. Nield, Acting Director, Motor Vehicle Safet Performance Service;
