Full Text of the Press Release from the USGA

The Olympic Club, San Francisco, 17th June 1998 - The United States Golf Association is proposing a test protocol that can objectively measure the "spring-like" effect in golf club heads. The test will be based on the rebound velocity of a golf ball off a club face.

While there may be some exceptions, it is the USGA's expectation and intent that virtually all of the golf clubs that have been submitted to the USGA will conform to this proposed test.

The USGA Technical Department has developed this protocol, which has been validated by outside experts. Since 1984, the Rules of Golf have stated that "the material and construction of the club shall not have the effect at impact of a spring" (Rule 4-1e, Appendix II). This reference is the only reference to "spring-like" effect in the Rules.

"In the literal sense, all clubs have some 'spring-like' effect because all clubs deform at impact," David Fay, USGA Executive Director, said. "Bob Jones' driver deformed at impact; the wooden-headed drivers used in the 1987 U.S. Open at The Olympic Club deformed at impact; and so do the thin-faced, large-headed drivers, which the majority of players in this year's U.S. Open will use."

In addressing this question of "spring-like" effect, the USGA has concluded that while the intent of the Rule is clear, the current language in the Rules book requires clarification. Thus, the Association has devised this test.

The USGA will release the particulars of the proposed test protocol to manufacturers within the next few weeks in advance of a meeting this Fall at the USGA's New Jersey headquarters, Golf House. This meeting will provide an opportunity for all interested parties, including manufacturers, to offer input on the test protocol.

"We do not believe that the 'spring-like' effect in clubs that are presently in use have lessened the skill required to play the game at championships such as the U.S. Open or at the recreational level," Fay said. "Golf constantly evolves. With an eye to the future, we have a responsibility to all involved with the sport to set objective, clearly understood standards that anticipate emerging technology while maintaining the fundamental challenge of the game."
