TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of February 2, 1972, in which you asked whether the temperature range specified in S6.2.6 of Motor Vehicle Safety Standard No. 121 was an initial temperature range or a range applicable throughout the stop.

In the new issuance of the standard, published in the February 24, 1972, issue of the Federal Register, the section has been amended to make it clear that the range is the range of initial brake temperature on each stop.
