* USGA TEST CREATES MANUFACTURER CONCERNS
By E. Michael Johnson
While causing less of a furor than its proposed new club regulations,
the USGA's plan to update its golf ball testing methodology, also
announced this week, has caught the eye of golf ball manufacturers.
"We have concerns about it," said Joe Nauman, senior VP and general
counsel for the Acushnet Co. "New equipment and launch conditions for the
test might prejudice certain ball constructions, ball types and ball
manufacturers."
There are three major components to the ball test changes:
--The USGA is proposing using an Indoor Test Range (ITR) to monitor the
overall distance a ball may travel, arguing that ITR results will be more
accurate than those from the current outdoor tests;
--Rather than scrap Iron Byron, the golf ball hitting machine, as had been planned previously, the USGA wants to use it to measure specific launch conditions, such as velocity, launch angle and backspin;
--Around March 1, 2002, the test conditions will change to reflect "a
manner similar to the way current highly skilled players drive the ball."
In addition, a modern golf ball and titanium driver will be used in
addition to the existing ball and club (a Pinnacle ball and Spalding
laminated wood club) to establish the Overall Distance Standard.
The USGA expects the Overall Distance Standard limit to change to
reflect the updated test conditions, but does not expect to alter the list
of conforming balls as a result of the launch condition update.
"We agree with modernizing launch conditions," said John Calabria, head
of ball R&D for Dunlop Slazenger Group Americas. But, he added, "If you're
not going to have any balls not conform, why change the test? . . . This
proposed change could obsolete a lot of our test data. If there are new
launch conditions, we'll have to re-test at those conditions
