IPX7 : IEC Standard of Water Resistance and Reliability
The IPX7 standard is a water resistance standard defined by the International Electrotechnical Commission (IEC), with the following specifications:
IPX7 Specifications
Testing Conditions:
Water Depth: The device must be tested in water at a depth of 1 meter.
Duration: The device should be submerged for 30 minutes.
Protection Requirements:Under these conditions, the device's enclosure must prevent water ingress and must not cause any harmful effects to the device.
Comparison of Water Resistance Ratings
| Rating | Meaning | Testing Requirements |
| IPX0 | No protection | No requirements |
| IPX1 | Protection against vertical dripping water | No harmful effects from dripping water (1mm/min, 10min) |
| IPX2 | Protection against dripping water at an angle of 15° | No harmful effects from dripping water (3mm/min, 2.5min) |
| IPX3 | Protection against spraying water | No harmful effects from spraying water (0.7L/min, 10min) |
| IPX4 | Protection against splashing water | No harmful effects from splashing water (10L/min, 10min) |
| IPX5 | Protection against water jets | No harmful effects from water jets (12.5L/min, 3min) |
| IPX6 | Protection against powerful water jets | No harmful effects from powerful jets (100L/min, 3min) |
| IPX7 | Protection against temporary immersion in water | No harmful effects when submerged in 1 meter of water for 30 minutes |
| IPX8 | Protection against continuous immersion in water | Customized depth and duration as specified by the manufacturer, with no harmful effects |
Important Considerations：
While IPX7 offers robust waterproof capabilities, it does not imply that the device can be safely used in all underwater conditions. For instance, exposure to strong currents or hot water may still cause damage. Therefore, when selecting a device, it's essential to consider the specific environment and requirements for use.
