Dear Mr. Rauscher:#This responds to your letter of October 9, 1974 requesting interpretation of Federal Motor Vehicle Safety Standard No. 106-74, *Brake hoses*, as applied to the labeling of air brake hose.#You have asked whether the designation 'AI-II' is permitted on hose for which the Type I and Type II dimensions listed in Table II are identical. Because such a designation is potentially misleading, it is not permitted. To comply with the standard, such hose should be labeled 'AI-AII'.#You have also asked whether hose labeled to indicate Type I or Type II dimensional characteristics may be used in brake hose assemblies which are constructed with permanently attached end fittings. S7.2 states:#>>>In the case of a hose intended for use in a reuseable assembly, 'AI' or 'AII' shall indicate Type I or Type II dimensional characteristics of the hose as described in Table III.<<<#Air brake hose which is designed for use with either permanent or reuseable end fittings falls within the meaning of 'hose intended for use in a reuseable assembly.' Therefore, such hose must be labeled with 'AI' or 'AII' (or 'AI-AII' as explained above.) Use of such hose with permanent end fittings is not prohibited under Standard No. 106-74.#Yours truly,Richard B. Dyson,Acting Chief Counsel;
