Rules for diving pool






Facilities Rules (FR)   FINA 2017-2021


The Facilities Rules are intended to provide the best possible environment for

competitive use and training. These Rules are not intended to govern issues related to

the general public. It is the responsibility of the owner or controller of a facility to provide

supervision of activities of the public.

General Requirements (FR 5.3)




FR 5.3.1

 For pools designed and constructed after March 1991 the minimum dimensions in metres for diving facilities as detailed on the “FINA

Dimensions for Diving Facilities” table and on the “Diving Facilities Diagram” shall prevail, using, as a basic measuring point of reference, the plummet line, which is a vertical line extending through the centre of the front edge of the springboard or platform. It is recommended that the preferred dimensions be used for projects considered to have an important status.

FR 5.3.2

 The dimensions C from plummet to adjacent plummet in the “FINA Dimensions for Diving Facilities” table apply to platforms with widths as detailed in FR 5.2.2. If platform widths are increased then the dimensions C shall be increased by half the additional widths.

FR 5.3.3

 The height of the springboards and each platform above the water level may vary by plus 0.05 metre minus 0.00 metre from the heights prescribed in the Rules.

FR 5.3.4

 The end of a 5 metre platform must not project beyond the ends of the 3 metre springboards.

FR 5.3.5

 In the area of full water depth, the bottom of the pool may rise up to 2%.In the diving pool, the depth of water shall not be less than 1.8 metres at any point.

FR 5.3.6

 In outdoor pools, springboards and platforms are recommended to face north in the northern hemisphere and south in the southern hemisphere.

FR 5.3.7

 The minimum illumination at a level of 1 metre above the water surface shall not be less than 600 lux.

FR 5.3.8

 Sources of natural and artificial illumination shall be provided with controls to prevent glare.

FR 5.3.9

 The water temperature shall be not less than 26° Celsius.

FR 5.3.10

 Mechanical surface agitation shall be installed under the diving facilities to aid the divers in their visual perception of the surface of the water. In pools equipped with an underwater bubble machine, the machine should only be used for this purpose if it creates sufficient water agitation when working with a very low pressure; otherwise a horizontal water sprinkler system should only be used.




Springboard diving (FR 5.1)


FR 5.1.1

 The boards shall be at least 4.8 metres long and 0.5 metre wide. At all FINA Events the type of springboard shall be determined by FINA.

FR 5.1.2

 The boards shall be provided with a satisfactory non-slip


FR 5.1.3

 The springboards shall be provided with movable fulcrums easily adjustable by the diver.

FR 5.1.4

 The vertical distance from the level of the platform, which supports the fulcrum assembly to the level of the top of the springboard, shall be 0.365 meter. The distance from the front edge of the fulcrum assembly (which is 0.676 meter long) to the front edge of the supporting platform shall be a maximum of 0.68 meter. If the front edge of the platform projects past this point then the top surface past this point must be sloped down at a rate of 1 vertical to 3 horizontal. FR 5.1.5

 The minimum distance recommended from the rear to the centre line of the fulcrum shall be to the recommendation of the manufacturer of the springboard.

FR 5.1.6

 The springboards shall be installed dead level at the leading edge when the movable fulcrum is in all positions.

FR 5.1.7

 The springboards should be placed on either one or both sides of the platform. For Synchronised Diving, it is preferred that at least two springboards at the same height shall be placed side by side and no objects should obstruct the visibility in any part of the dive between the divers.



Platform diving (FR 5.2)


FR 5.2.1

 Each platform shall be rigid and horizontal.

FR 5.2.2

 The minimum dimensions of the platform shall be:

0.6m to 1.0m platform 0.6m width 5.0m length

2.6m to 3.0m platform 0.6m width 5.0m length

(preferred 1.5m)

5.0m platform 1.5m width 6.0m length

7.5m platform 1.5m width 6.0m length

10.0m platform 3.0m width 6.0m length

On 10m platforms, with a width of less than 3m, only the handrails one ach side for a distance of at least 3.0m back from the front edge of the platform may be shaped as detailed below. It is recommended that an easily removable section of handrail be included for general use, which can be removed for synchronised diving (see diagram).

FR 5.2.3

 The preferred thickness of the front edge of the platform shall be 0.2 metre but not exceeding 0.3 metre, and can be vertical or inclined at an angle not greater than 10° to the vertical inside the plummet line.

FR 5.2.4

 The surface and the front edge of the platform shall be covered throughout with a resilient non-slip surface. The two

surfaces shall be covered separately in order to achieve clean 90° angle or as described in FR 5.2.3.

FR 5.2.5

 The front of 10.0 metre and 7.5 metre platforms shall project at least 1.5 metres beyond the edge of the pool. For 2.6 metre - 3.0 metre and 5.0 metre platforms a projection of 1.25 metres is acceptable, and for 0.6 metre - 1.0 metre platforms a projection of 0.75 metre is acceptable.

FR 5.2.6

 Where a platform is directly underneath another platform the platform above shall project a minimum of 0.75 metre (preferred 1.25 metres) beyond the platform below.

FR 5.2.7

 The back and sides of each platform (except a 1.0 metre platform) shall be surrounded by handrails with a minimum clearance of 1.8 metres between pairs. The minimum height

shall be 1.0 metre and they shall be with at least two crossbars placed outside the platform beginning 0.8 metre from the front edge of the platform.

FR 5.2.8

 Each platform shall be accessible by suitable stairs (not ladders).

FR 5.2.9

 It is preferable that a platform is not constructed directly under any other platform.

FR 5.2.10

 Requirements for the supporting structure. For platforms and supporting structure of the springboards the design load is p =350 kiloponds (kilograms force) per lineal metre. In addition to the static requirements and for the comfort and safety of the user with respect to the movement of the towers, the following limits shall be observed, with respect to the platforms and springboard supports. Fundamental frequency of platforms 10.0 Hz Fundamental frequency of tower 3.5 Hz Oscillation of total structure 3.5 Hz. The spatial deformation of the front edge of the platforms as a result of Px = Py = Pz = 100 kiloponds (kilograms force) shall be a maximum of 1 mm (see drawing). These requirements can be met most adequately by a reinforced concrete structure. The proof of the dynamic behaviour is to be provided together with the static calculations for the whole structure.
