Dear Mr. Cope:#This responds to your recent letter asking a questio concerning Safety Standard No. 106, *Brake Hoses*. You note that there is an ambiguity in the formula referenced in paragraph S8.3.2(e) of that standard as set forth in the *Code of Federal Regulations*. Specifically, you ask whether the entire fraction that is specified is multiplied by '100' or whether only the denominator of the fraction is multiplied by '100'.#The correct formula is as follows:#>>>[((W3-W4) - (W1-W2)) / (W1- W2)] X 100<<<#The formula as specified in the *Code of Federal Regulations* should, therefore, include additional brackets around the fraction, separating the fraction from the 'X 100' figure. We will notify the *Federal Register* concerning this error.#I hope this has clarified any misunderstanding you may have had.#Sincerely, Frank Berndt, Chief Counsel;
