Waterproof, splashproof, water-resistant… these mentions can sometimes be confusing for the shower speaker buyer. Indeed, these are just vague appellations put there for commercial reasons.
On the other hand, you have probably already noticed mentions such as “IPX7” or “IP69”. These statements indicate the actual degree of protection against intrusions.
The International Protection Marking
The IP code (International Protection Marking, sometimes called Ingress Protection Marking) is an international standard of the International Electrotechnical Commission published for the first time in 1989. It is adopted by the European standard EN 605293.
This index classifies the level of protection offered by a material against intrusions of solid and liquid bodies.
The format of the index, given by the IEC 60529 standard, is IP XX where the characters XX are two digits and / or one letter. The figures indicate compliance with the conditions summarized in the table below. When no criterion is met, the digit may be replaced by the letter X.
A shower speaker is often rated IPX followed by a number. This means that only its water resistance properties have been tested.
|1||Protected against vertical drops of water.|
|2||Protected against drops of water up to 15° from the vertical.|
|3||Protected against falling water up to 60° from the vertical.|
|4||Protected against splashing water from all directions.|
|5||Protected against jets of water from all directions (nozzle: 6.3 mm, distance: 2.5 m to 3 m, flow: 12.5 l / min ± 5%).|
|6||Protected against strong jets of water from all directions (nozzle: 12.5 mm, distance: 2.5 m to 3 m, flow: 100 l / min ± 5%).|
|7||Protected against the effects of temporary immersion (up to 1 m) and for 30 minutes.|
|8||Submersible equipment under conditions specified by the manufacturer (prolonged immersion) beyond 1 m.|
|9||Submersible equipment under conditions specified by the manufacturer (extended immersion) beyond 1 m and Protection against high pressure cleaning.|
|9K||Protection against high pressure, high temperature cleaning from multiple directions.|
Splashproof or Waterproof?
In summary, it can be said that a device is splashproof from the protection index 4 and waterproof from the protection index 5. From the index 7, the device can be completely immersed in water, and from the index 9, it resists high pressure cleaning.
