196 FR 2.1.12 False Start Rope False Start Rope may be suspended across the pool not less than 1.2 metres above the water level from fixed standards placed 15.0 metres in front of the starting end. It shall be attached to the standards by a quick release mechanism. The rope must effectively cover all lanes when activated. FR 2.1.13 Water conditions FR 2.1.13.1 Water Temperature Water temperature shall be 25° to 28°. FR 2.1.13.2 Water Movement During competition, the water in the pool must be at a constant level, with no appreciable movement. In order to keep the water level, preserve the transparency of water and take into consideration the health regulations in force in most countries, inflow and outflow has to be regulated as follows: • 220 to 250 m3/h for 50.00 m pools • 150 to 180 m3/h for 33.33 m pools • 120 to 150 m3/h for 25.00 m pools In daily use, inflow and outflow has to follow the health regulation of each country. At these turnover rates, the water distribution has to be such that no appreciable current or turbulence is created. “Appreciable current” is defined as water movement that can move a floating basketball (filled with 6 litres of water to obtain the right buoyancy) in one direction for more than 1,25m in 60 seconds. The practical way to test this is to install two floating lines crosswise in a swim lane (to obtain a square with 2,5m size, ref. Image 1) and then to leave the basketball in the central point of the square. If the ball does not touch any of the four lane ropes within 60 seconds, the turbulence test is successful. Test should be repeated in lanes 1,3,6,8 on two sides, at 5m from each headwall.
