Conforming Golf Balls Effective August 1, 2007 The List of Conforming Golf Balls will be updated effective the first Wednesday of each month. The updates will be available for download the Monday prior to each effective date. Please visit www. usga.org or www.randa.org for the latest listing. *Please note that the list is updated monthly (i.e., golf balls are added to and deleted from the list each month). The effective period of the Conforming Ball List is located on the top of each page. To ensure accurate rulings, access and print the Conforming Ball List by the first Wednesday of every month. HOW TO USE THIS LIST To find a ball: The balls are listed alphabetically by Pole marking ( brand name or Manufacturer name ), then by Seam marking. Each ball type is listed as a separate entry. For each ball type the following information is give to the extent that it appears on the ball. * 1. Pole marking(s). For the purpose of identification, pole markings are defined as the major markings, regardless of the actual location with respect to any manufacturing seams. 2. Color of cover. 3. Seam marking(s). For the purpose of identification, seam markings, on the equator of the ball, are defined as the minor markings, regardless of the actual location with respect to any manufacturing seams. *NOTE: Playing numbers are not considered to be part of the markings. A single ball type may have playing numbers of different colors and still be listed as a single ball type. READING A LISTING Examples of listings are shown on the next page with explanatory notes. The format is the same on each page. The main pole marking and the main seam marking (if any) are set to the left margin, while any second pole or seam markings are indented. In view of the complexity of the markings on some brands, players and officials should take great care, in events in which the List is in operation, to ensure that the ball corresponds exactly to the description of one of the listed brands. If there is any doubt the ball should not be used. Additional information provided by the manufacturer describing the ball construction, spin rating and the number of dimples is included in the list. COLOR The color column lists the cover color of the ball for those ball types with cover colors other than white. If no color is listed the cover color is white.
