Dear Mr. Dvorachek:#This responds to your letter of October 25, 1974 requesting an interpretation of Standard No. 106-74, *Brake hoses*, as it applies to the labeling of air brake hose end fittings which use sacrificial sleeves.#>>>S7.2 states:#In the case of an end fitting intended for use in a reuseable assembly, 'AI' or 'AII' shall indicate use with Type I or type II hose respectively.<<<#Since an end fitting which uses a sacrificial sleeve is defined by S4 to be a permanently attached end fitting, it does not fall into the classification 'End fitting[s] intended for use in a reuseable assembly.' Therefore, it must be labeled with the designation 'A' rather than any of the following: 'AI', 'AII', 'AI-AII'.#Yours truly,Richard B. Dyson,Acting Chief Counsel;
