FOREWORD (This Foreword is not part of ASME B5.10-1994.) The American Standard for Machine Tapers was formulated by the Section
9、al Committee on the Standardization of Small Tools and Machine Tool Elements organized in September 1922, under the procedure of the American Standards Association. This project is now sponsored by the NMTBA, SAE, ASTE, and the ASME. The importance of unifying American practice in the use of machine
10、 tapers had been recognized for some time and it was known that certain European countries had adopted as their national standards certain selections and slight modifications of the three American tapers then in use, the Brown Nos. 400 to 600 inclusive, 3/32 inch deep; Nos. 800 to 1200 inclusive, /8
