DETERMINATION OF GROOVE CONFORMANCE 溝槽符合規格之決定
(Impact Area Markings(App II, 5c) Measurement Procedure)(撞擊區域線條(附錄II, 5C)量測程序)
Revision: 4th March 2009 改版日期: 2009年3月4日
This procedure describes the methods used to determine the conformance of impact area markings to the Rules from beyond 1st January 2010.
此程序說明從2010年1月1日起決定撞擊區域線條符合規格所使用之方法。
IMPACT AREA 撞擊區域
The impact area on irons will be taken to be the entire extent of the face where a face treatment has been applied (for instance grooves, sandblasting etc.) or the central strip down the middle of the clubface having a width of 1.68” (42.67mm), whichever is greater.
鐵桿的撞擊區域是指桿面已被用到(例如溝槽或噴砂處理等等‧‧‧)的全部範圍，或是桿面中間以寬度為1.68”(42.67mm)做條狀分割，只要是比該數值大者。
From 1st January 2010 the impact area on drivers and fairway woods will be defined as the central strip down the middle of the clubface having a width of 1.68” (42.67mm).
從2010年1月1日起，一號木桿及球道木桿之撞擊區域，也將以其桿面中間以寬度為1.68”(42.67mm)做條狀分割作為界定之依據。
Grooves and/or punch marks indicating a traditional impact area or any groove which encroaches into the impact area by less than 0.25” (6.35mm) will not be considered to be within the impact area and hence does not need to meet the specifications detailed in the following sections, unless they are designed to unduly influence the movement of the ball.
用來標示一個傳統撞擊區域的溝槽及/或衝擊紋路或任何在撞擊區域內深度小於0.25”(6.35mm)之溝槽，將不被認為在撞擊區域範圍內，因此不須符合以下段落詳述之規格，除非它們的設計是為了要不正當地改變球的移動。 |
