TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of January 10, 1974, to Mr. Schneider.

It is uncertain whether "some time in July of 1974 Federal standards will become effective relating to silicone brake fluids." The proposed effective date for DOT 5 fluids is July 1, 1974, but the comments on this rulemaking action are still under consideration and the actual effective date, if the proposal is adopted, will probably be somewhat later.

It is true that S5.4.3 of Standard No. 105a does not require that all reservoir labelling be "DOT 3." The letters "e.g." mean "for example." If DOT 4 is the recommended fluid then "DOT 4" would be the appropriate insertion in the required statement.
