FOREWORD

Recognizing the need for a standard for mechanical power presses, the ASME Committee on Machine Tools and Components (B5) established in December 1973, Technical Committee 30 to develop an American National Standard addressing the interchangeability of bolsters, press tooling, and mounting provisions between general purpose presses of comparable bed size, capacity, and type.

The B5-TC30 membership consists of a balance between manufacturers, users, accessory suppli- ers and others associated with power presses. The technical committee’s work was based on the Joint Industry Conference (JIC) Press Room Standards, once the most widely used document, to develop a standard for mechanical power presses, and basic data submitted by U.S. manufacturers of power presses.

In April 1983, the committee completed the final draft of “Standard for Straight Side Type Presses (Metric).” This draft was not submitted for approval before the committee became inactive. In 1995, Technical Committee 30 was reestablished to continue the pursuit of the original objectives set forth in 1973. The scope of the Standard was expanded to include hydraulic power

presses.

ASME B5.61-2003 was approved by the American National Standards Institute on July 7, 2003.
