IP ratings are crucial indicators of how well your mobile device is protected against dust and water. This standardized international system helps you make informed decisions when purchasing a device that might be exposed to these elements.
What is an IP Rating?
An IP (International Protection) rating consists of two numbers following the letters "IP":
- The first number indicates protection against solid particles like dust
- The second number indicates protection against water
Understanding the Rating Scale
Dust Protection (First Digit):
| Digit | Protection Level |
|---|---|
| 0 | No protection |
| 1 | Protection against objects larger than 50mm |
| 2 | Protection against objects larger than 12.5mm |
| 3 | Protection against objects larger than 2.5mm |
| 4 | Protection against objects larger than 1mm |
| 5 | Dust-protected (dust may enter but won't interfere with operation) |
| 6 | Completely dust-tight |
Water Protection (Second Digit):
| Digit | Protection Level |
|---|---|
| 0 | No protection |
| 1 | Protection against dripping water |
| 2 | Protection against dripping water when tilted at 15 degrees |
| 3 | Protection against rain at 60-degree angle |
| 4 | Protection against water splashes |
| 5 | Protection against water jets from all directions |
| 6 | Protection against powerful water jets |
| 7 | Protection against temporary immersion (up to 1 meter for 30 minutes) |
| 8 | Protection against continuous immersion (1 meter or deeper) |
Important Considerations
1. Water Exposure Limitations:
- Even with high water resistance ratings, swimming or bathing with devices isn't recommended
- Impact when dropping into water can exceed testing conditions
- Manufacturers typically specify maximum depth limits (usually under 3 meters)
2. Testing Conditions:
- IP ratings are based on freshwater testing only
- Avoid exposing devices to hot water or saltwater, even if water-resistant
- Laboratory testing may not reflect real-world conditions
3. Device Maintenance:
- Normal wear and tear can affect water and dust resistance
- Damage may not be visibly apparent but can compromise protection
- Always ensure ports and covers are properly sealed
What to Do If Your Device Gets Wet
Important:
Never charge your device when wet and wait at least 5 hours after drying before attempting to charge.
1. Immediate Actions:
- If exposed to saltwater or other liquids, rinse gently with fresh tap water
- Dry with a soft, lint-free cloth
- Gently tap the device against your hand with ports facing down to remove water
- Use cold air to dry; never use heat sources
2. Charging Safety:
- Wait at least 5 hours after drying before charging
- Avoid both wired and wireless charging when device is wet
- Ensure all ports and openings are completely dry before use
Remember that while IP ratings provide valuable information about device protection, they shouldn't be taken as an invitation to deliberately expose your device to water or dust. Always consult your device's user manual for specific guidance on water and dust exposure limits.
Frequently Asked Questions
IP68 means that the device is completely dustproof (6) and can withstand continuous immersion in water deeper than 1 meter (8). The exact specifications for depth and duration vary between manufacturers.
An IP68 rating means that the product is water-resistant under controlled conditions, such as still freshwater. Swimming involves movement, pressure, and often chlorinated or salt water – which are not covered by the IP test. Check the manufacturer's specifications for details about water depth, duration, and water type.
Note: Warranty often does not cover water damage – even on IP68-rated products.
Waterproof: In practice, this means it can be used in water, but only if the manufacturer explicitly states so – for example "designed for swimming" or "can be used in saltwater".
Water-resistant: This typically means protection against brief exposure – such as rain, showering, or if the device is dropped in water.
