Dear Mr. Tanaka:#This responds to your letter of February 15, 1975 requesting an interpretation of the adhesion requirements of Federal Motor Vehicle Safety Standard No. 106-74, *Brake Hoses*.#You have presented a diagram of multilayer air brake hose and suggested that S7.3.7 of the standard applies only to the adhesion between the outer cover and the upper braid of the hose. That interpretation is incorrect. The requirement of S7.3.7 is that:>>>An air brake hose shall withstand a tensile force of 8 pounds per inch of length before separation of adjacent layers (S8.6).<<<#The NHTSA interprets this requirements as applying to each pair of adjacent layers of the hose, not merely to the outermost pair.#Yours truly, James C. Schultz, Chief Counsel;
