Dear Mr. Dandy: This is in reply to your letter of July 26, 1972, on the subject o seat belt retractor testing under S5.2(k) of Motor Vehicle Safety Standard No. 209.; Your outline of the emergency locking retractor test procedure i essentially correct. During the initial 5,000 cycles, however, the belt is to be retracted completely, even though some vehicle installations may prevent complete retraction. The assumption in (3)(ii) of your letter is therefore incorrect.; The remaining points in your interpretation are correct. Sincerely, Richard B. Dyson, Assistant Chief Counsel
