TOILET/CHANGE OF ATTIRE BREAK A player is allowed to request permission to leave the court for a reasonable time for a toilet break / change of attire break. Change of attire breaks must be taken on a set break and toilet breaks should be taken on a set break. In singles, each player is entitled to a maximum of two (2) breaks per match. In doubles each team is entitled to a maximum of two (2) breaks. If partners leave the court together, it counts as one (1) of the team's authorised breaks. These breaks may be taken for toilet visits, change of attire, or both, but for no other reason whatsoever. Any time a player leaves the court for a toilet or change of attire break, it is considered one of the authorised breaks regardless of whether or not the opponent has left the court. Any toilet break taken after a warm-up has started is considered one of the authorized breaks. Additional breaks will be authorised but will be penalised in accordance with the Point Penalty Schedule if the player is not ready to play within the allowed time. Any player abuse of this rule will be subject to penalty in accordance with the Unsportsmanlike Conduct section of the Code of Conduct. EXTREME WEATHER CONDITIONS Extreme weather conditions shall be defined at such time that heat, as measured by a Heat Stress Monitor, meets or exceeds a heat stress index of 30.1 degrees Celsius/86.2 degrees Fahrenheit. If a Heat Stress Monitor is not available, extreme weather conditions are then defined by the danger zone which is equal to or above the apparent temperature of 34 degrees Celsius/93 degrees Fahrenheit, illustrated on the chart below. Heat stress is measured by Wet Bulb Global Temperature (WBGT) which is calculated as (0.7 Wet Bulb + 0.2 Global Temperature + 0.1 Dry Bulb = WBGT). Apparent Temperature (what it is like) Fahrenheit 70° 75° 80° 85° 90° 95° 100° 105° 110° 115° 120° Relative Humidity 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 64 65 66 67 68 69 70 70 71 71 72 69 70 72 73 74 75 76 77 78 79 80 73 75 77 78 79 81 82 85 86 88 91 78 80 82 84 86 88 90 93 97 102 108 83 85 87 90 93 96 100 106 113 122 87 90 93 96 101 107 114 124 136 91 95 99 104 110 120 132 144 95 100 105 113 123 135 149 99 105 112 123 137 150 103 111 120 135 151 107 116 130 148 69
