Dear Mr. Chermak:#This responds to your June 24, 1974, question whethe brake hose manufactured before September 1, 1974, to comply with all performance requirements of Standard No. 106-74, *Brake hoses*, may be marked with the DOT symbol after that date, and whether the DOT may be used on hose, fittings, and assemblies prior to that date.#The answer to your questions is no. The DOT symbol means that a vehicle or item of motor vehicle equipment was manufactured in compliance with a Federal motor vehicle safety standard and that it complies with the standard. Therefore, the DOT symbol can not be placed on hose, fitting or assemblies manufactured before the date the standard becomes applicable to them, whether or not the DOT is actually placed on the hose before or after the effective date.#With regard to your supply of pre-106 vacuum hose, it may be used in assemblies as late as February 28, 1975, and in vehicles as late as August 31,1975, if it is only clamped to the vehicle and not made into assemblies.#Yours truly,Richard B. Dyson,Assistant Chief Counsel;
