Water projected by a nozzle
(6.3mm) against enclosure
from any direction shall have
no harmful effects.
Water projected in powerful
jets (12.5mm nozzle) against
the enclosure from any
direction shall have no
harmful effects.
Ingress of water in harmful
quantity shall not be possible
when the enclosure is
immersed in water under
defined conditions of pressure
and time
(up to 1 m of submersion).
The equipment is suitable for
continuous immersion in water
under conditions, which shall be
specified by the manufacturer.
Normally, this will mean that the
equipment is hermetically
sealed. However, with certain t
ypes of equipment, it can mean
