702 Swimming pools and other basins
702.1 Scope, object and fundamental principles
702.11 Scope
The particular requirements of this section apply to the basins of swimming pools, the basins of
fountains and the basins of paddling pools. They also apply to the surrounding zones of all these
basins. In these areas, in normal use, the effect of an electric shock is increased by a reduction in
body resistance and contact of the body with earth potential. Swimming pools within the scope of
an equipment standard are outside the scope of this standard. For swimming pools for medical
purposes special precautions may be necessary.
Except for areas especially designed as swimming pools, this section does not apply to natural
waters, lakes in gravel pits, coastal areas and similar areas.
702.12 Normative references
See annex ZA.
702.2 Definitions
702.2.21 Guide to general terms
For the purpose of this section, the following definitions apply. For other general definitions, see
HD 384.2.
702.2.21.1
basin of fountain
basin not intended to be occupied by persons and which cannot be accessed (reached by persons)
without the use of ladders and similar means. For basins of fountains which may be occupied by
persons, the specifications and requirements for swimming pools apply
702.2.21.2
small swimming pool
a pool where there is no zone 2
702.3 Assessment of general characteristics
702.32 Classification of external influences
These requirements are based on the dimensions of three zones (examples are given in
Figures 702A, 702B, 702C and 702D).
Zones 1 and 2 may be limited by fixed partitions having a minimum height of 2,5 m.
a) Zone 0
This zone is the interior of the basins including any recesses in their walls or floors, basins
for foot cleaning and waterjets or waterfalls and the space below them.
b) Zone 1
This zone is limited by
- zone 0,
- a vertical plane 2 m from the rim of the basin,
- the floor, or the surface expected to be occupied by persons,
- the horizontal plane 2,5 m above the floor or the surface expected to be occupied by
persons.

When the swimming pool contains diving boards, spring boards, starting blocks, chutes or other
components expected to be occupied by persons, zone 1 comprises the zone limited by
- a vertical plane situated 1,5 m around the diving boards, spring boards, starting blocks, chutes
and other components such as accessible sculptures and decorative basins,
- the horizontal plane 2,5 m above the highest surface expected to be occupied by persons.
c) Zone 2
This zone is limited by
- the vertical plane external to zone 1 and a parallel plane 1,5 m from the former,
- the floor or surface expected to be occupied by persons,
