In order to detect the product’s waterproof rating, we often use different rain testers or rain test chambers to carry out. For different waterproof levels, you should use different test conditions. Here are the IPX waterproof rating and main test conditions for your reference:
IPX waterproof rating chart
| Grade code | Experiment method | Test flow condition | Test duration requirements |
| IPX0 | No test needs to be tested | —— | —— |
| IPX1 | The shell is placed on the turntable | 1+0.50mm/min | 10min |
| IPX2 | The shell is placed at four fixed positions for 15 degrees | 3+0.50mm/min | Four tilted positions 2.5min |
| IPX3 | Rain in the range of + 60 degrees in the vertical direction, the maximum distance of 200mm, or in the range of + 60 degrees in the vertical direction | Each hole 0.07(1±5%)L/minor 10(1± 5%)L/min | 10min 1min/m2at least 5min |
| IPX4 | Same as the IPX3 test, the angle is in the range of + 180 degrees in the vertical direction | Same as IPX3 | Same asIPX3 |
| IPX4K | With the vertical direction of 180&deb; the range of water, and the maximum distance of 200mm | Each hole 0.6(1±5%)L/min | 10min |
| IPX5 | The diameter of the nozzle is 6.3mm, and the distance is 2.5~3m | 12.5(1± 5%)L/min | 1min/m2 at least 3min |
| IPX6 | The diameter of the nozzle is 12.5mm, and the distance is 2.5~3m | 100(1±5%)L/min | 1min/m2at least 3min |
| IPX6K | The diameter of the nozzle is 6.3mm, and the distance is 2.5~3m | 75(1±5%)L/min | 1min/m2at least 3min |
| IPX7 | Using a submersible, the water surface is at least 0.15m above the top of the shell, and the bottom of the shell is at least 1m under water. | —— | 30min |
| IPX8 | Using a submersible box, the height of the water surface is negotiated by the manufacturer and the user | —— | Negotiation by both parties |
| IPX9K | Rotation speed (5 + 1) r/minWater temperature (80 + 5) CWater pressure (8000~10000) kPaAt the 0, 30, 60, and 90 degrees, the spraying of the spaced sample (100~150) mm | (14~16)L/min | Each angle position is 30s, a total of 120s |
