Effective 5 December 2020 and amended 27 November 2021
Changes 27 November 2021 as follows:
14.4.1. Self-inflicted: where the Blood Injury is caused by a player’s own action or condition, such as a fall, lunge, dive, crowding, nosebleed or similar, the player is permitted 5 minutes to stem the flow of blood and cover the bleeding. The referee is in charge of starting the timer, which will start from when the injured player’s treatment begins. If the injured player is not ready to resume play after 5 minutes has elapsed, the player must concede the game and take the game interval, if available, for further recovery.
If the same Blood Injury reoccurs, no further recovery time is permitted, and the injured player must concede the game and take the next game interval, if available, for further recovery.
If the same Blood Injury reoccurs and is caused by both players’ actions (see 14.4.2 Contributed) the injured player shall have further reasonable time to address the Blood Injury.
If the injured player cannot resume play within the permitted time allowed, the referee will award the match to the injured player’s opponent.
APPENDIX 8 – SPECIFICATIONS OF SQUASH BALLS
2. No specifications are set for faster or slower speeds of ball, which may be used by players of greater or lesser ability or in court conditions which are hotter or colder than those used to determine the Club and Competition specifications. Where faster speeds of ball are produced they may vary from the diameter and weight in the above specifications. It is recommended that balls bear a permanent colour code or marking to indicate their speed or category of usage. It is also recommended that balls for beginners and improvers conform generally to the rebound resilience figures below.
Beginner Rebound resilience @ 23 degrees C not less than 17%
Rebound resilience @ 45 degrees C 36% to 38%
Improver Rebound resilience @ 23 degrees C not less than 15%
Rebound resilience @ 45 degrees C 33% to 36%
Specifications for balls currently fulfilling these requirements can be obtained from the WSF on request.
The speed of balls may also be indicated as follows:
Super slow – double yellow dot & green dot (high altitude ball)
Slow – single yellow dot
Medium – red dot (this ball can be larger than 40mm diameter)
Fast – blue dot (this ball can be larger than 40mm diameter)
