Dear Mr. Weiher: This responds to your August 2, 1978, letter asking whether it i permissible to perform the tests of Standard No. 124, *Accelerator Control Systems*, with only part of the vehicle mechanism at the designated temperatures. You state further that there is not sufficient time to find an environmental chamber large enough to accommodate the size vehicle that you are testing.; "The National Highway Traffic Safety Administration (NHTSA) does no issue approvals of manufacturer's plans for compliance with agency standards. Standard No. 124 mandates that a vehicle shall meet the j requirements of the standard at any temperature between -40 degrees F. and 125 degrees F. When the agency tests for compliance with the standard, it fins a chamber sufficiently large to accommodate the entire vehicle and tests according to the standard. Any manufacturer deviation from this accepted test procedure carries with it certain risks that a vehicle may not conform to the requirements."; With respect to the vehicles that you are constructing, you state i your letter that they are being manufactured for use by the army. As such, These vehicles are not required to comply with the agency's safety standards, and the NHTSA would not test these vehicles for compliance.; Sincerely, Joseph J. Levin, Jr., Chief Counsel
