Water Ingress Testing is conducted to ensure the product is able to operate safely in it’s intended end-use. Depending on the intended use the test may involve dripping, spraying, or submerging the product under water. Depending on the water ingress code one of the following tests may be conducted. For further information refer to Wikipedia here.
Water Ingress Testing :: Code Variants
IPX1 Dripping water
Dripping water (vertically falling drops) shall have no harmful effect. Test duration: 10 minutes, equivalent to 1 mm rainfall per minute.
IPX2 Dripping water when tilted up to 15°
Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position. Test duration: 10 minutes, Water equivalent to 3 mm rainfall per minute.
IPX3 Spraying water
Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect. Test duration: 5 minutes, volume: 0.7 litres per minute, Pressure 80–100 kPa.
IPX4 Splashing of water
Water splashing against the enclosure from any direction shall have no harmful effect. Test duration: 5 minutes, volume: 10 litres per minute, Pressure 80–100 kPa
IPX5 Water jets
Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects. Test duration: at least 15 minutes, volume: 12.5 litres per minute, pressure 30 kPa at distance of 3 m.
IPX6 Powerful water jets
Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects. Test duration: at least 3 minutes, volume: 100 litres per minute, pressure 100 kPa at distance of 3 m.
IPX6-K Powerful water jets with increased pressure
Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction, under elevated pressure, shall have no harmful effects. Test duration: at least 3 minutes, Water volume: 75 litres per minute, Pressure: 1000 kPa at distance of 3 m.
IPX7 Immersion up to 1 m
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). Test duration: 30 minutes, Immersion at depth of at most 1 m measured at bottom of device, and at least 15 cm measured at top of device.
IPX8 Immersion beyond 1 m
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 sealeed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. Test duration: continuous immersion in water, Depth specified by manufacturer, generally up to 3 m.
Why Water Test?
Most electronic products will be exposed to water in one form or another over their life. Whether this be through direct contact as with rain, puddles, dew or even your garden hose – or in the home near kitchens, bathrooms or anywhere a drink could spill. The standard exists to ensure the product is safe in it’s intended end-use environment. It is therefore up to the designers to determine an adequate level of protection, and a test to confirm compliance.
We’re here to help and can advise you on which levels to test to. Ultimately we take a test-to-failure approach during development testing, and can provide a tiered test plan comprised of multiple steps until the product fails. This provides accurate margin information over and above the normal “pass/fail” compliance test.
