Dear Mr. Mitchell:
This responds to your letter asking about the hydraulic brake hose labeling requirements (S5.2) of FMVSS 106, Brake Hoses. You indicated that your current brake hoses have two stripes, on opposite sides of the hose. Each of the stripes is interrupted by a line of information. One line, which you call the "DOT print line," contains the information required by FMVSS 106. The other line, which you call the "SAE print line," contains certain information not required by FMVSS 106, including "batch and shift" information.
You asked whether it is permissible to place the batch and shift information (consisting of a mark such as "AA") on the DOT print line. You stated that moving the batch and shift mark to the DOT print line would improve the legibility of the SAE print line. This is because better print materials could be used in the SAE print line if that legend did not contain a mark that must be updated on a daily or more frequent basis, such as the batch and shift mark. As discussed below, the batch and shift information may not be placed on the same line as the required information.
NHTSA's longstanding position, stated in past rulemaking notice preambles (e.g., 39 FR 7425, February 26, 1974; 39 FR 24012, June 28, 1974), is that the DOT print line may only contain the required information. The striping requirement (S5.2.1) of FMVSS 106 states that one of the requisite stripes on a brake hose "may be interrupted by the information required by S5.2.2, and the other stripe may be interrupted by additional information at the manufacturer's option." We interpret this to mean that the stripe that is interrupted by the required information may not be interrupted by information voluntarily provided by the manufacturer. This conclusion is consistent with the preamble for the final rule establishing S5.2.1 (38 FR 31302, November 13, 1973), which refers to optional additional information as not being permitted in the legend that interrupts the first stripe. (That rule modified the labeling requirements to permit interruption of the second stripe with the optional information.) NHTSA did not permit optional information to be mixed with the required information because the mixture of optional and required labeling could obscure or confuse the meaning of the required information, or interfere with the appearance of complete labeling on some hose assemblies.
For your information, we have enclosed the Federal Register documents cited above. Please contact Ms. Fujita of my staff at (202) 366-2992 if you have any further questions.
Sincerely,
Paul Jackson Rice Chief Counsel
