Swimming pools have drawn huge crowds as temperatures in the northen hemisphere have often exceeded 35°C this summer. While grateful swimmers splash about in the chlorine, a number of electrical devices are used behind the scenes to make sure the water is clean and safe.
The IEC publishes a wide number of International Standards which enable these devices to be employed safely. Electricity and water can be a dangerous mix and accidents can best be avoided by following a widely recognized set of international guidelines.
Chief among these is IEC 60364-7-702 which, among other things, defines the dimensions of the zones equipped with electrical equipment and stipulates which must go where. It also specifies the characteristics of wiring and current-based equipment used in swimming pools.
Robotic pool cleaners are used to suction debris such as hair, leaves even sun oil out of the water and keep it crystal clear. IEC TC 61 prepares Standards for household appliances such as water suction cleaning appliances, as well as vacuum cleaners.
In-pool alarm systems are also increasingly a must: as parents become more and more addicted to their mobile phones, the chances of their children having a pool-related accident sky-rocket. Floating wave sensors are battery powered and mounted on the edge of the pool or in the water.
They can detect unwanted movement in the water and are mostly used in privately-owned swimming pools. Wrist-band alarms can be fitted on children and work in a similar fashion, using sensors. IEC TC 79 prepares Standards in that area as well as IEC TC 47, which issues most of the publications relating to sensors. Standards for batteries are developed by IEC TC 21.
Last but perhaps not least for some, if you happen to drop your smartphone in the water, the IEC has drawn up the Standard to determine how resistant it can be to water: IEC 60529 , known in the industry as IP, the International Protection Marking, classifies and rates the degree of protection provided against water by mechanical casings and electrical enclosures.
