TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of September 25, 1973, asking whether the fuel spillage measurement specified in Standard No. 301 is an average rate of one onunce per minute (your Item A) or an actual rate. (Your Item B)

Your item B is correct. Fuel spillage shall not exceed one ounce per minute in any one of the fifteen minutes of the observed period.

YOURS TRULY,

NISSAN MOTOR CO., LTD.

Lawrence Schneider Chief Council National Highway Traffic Safety Administration

This is to ask your interpretation regarding the test procedures of MVSS 301 Fuel System Integrity published in Federal Register, Vol. 38, No. 160 (Docket No. 70-20) on August 20, 1973.

We feel that the fuel spillage requirement following cessation of vehicle motion of S.5.4 has the following two meanings:

A) The calculated fuel spillage rate.

Total amount of fuel spillage (oz.)

B) The measured fuel spillage rate every minute. All of the collected fifteen one-minute timed samples shall not exceed one ounce per minute.

We would like to know which definition is correct understanding. Your prompt reply would be greatly appreciated.

Very Truly Yours,

Tatsuo Kato
