Are you still confused by the dazzling waterproof markings on various electronic products? Don't worry! Precision Industrial Technology today to take you a one-timeGet a thorough understanding of IPX7, IPX8, IP67, IP68, IP69 - the most common waterproofing ratings.We will let you buy waterproof products from now on without any confusion!
Waterproof ≠ omnipotent, your product is really "safe"?
Behind the stories of smartphones "surviving" water falls and outdoor equipment operating stably in rainstorms is the hardcore support of IP protection ratings. However, many users and even manufacturers have misconceptions about IP ratings:Why is IPX8 always better than IPX7, why is IP68 both dust and water resistant, and why is IP69 often favored in industrial applications?
As a technical expert who has been plowing into the field of airtightness testing for more than ten years, Jingcheng Industrial Technology tells you with actual measurement data and cases: the difference of waterproof level determines the life and death line of the product.
From "Leakage" to "Zero Defects", how we overcome the IPX8 hurdle
In 2019, a well-known cell phone brand had suffered a mass production and large-scale rework crisis due to substandard IPX7 waterproof performance. Precision Engineering was assigned to analyze the root cause of the problem. Through high-precisionAirtightness Testerof repeated testing, we found that theThe problem lies in the tiny sealing ring - its shrinkage deviation under temperature difference is only 0.05mm, but this small deviation is enough to allow water vapor to penetrate the circuit board and cause the product to fail.

The Precision Engineering team didn't stop there. We rose to the challenge, optimized the testing parameters, increased the pressure accuracy to ±1Pa, and controlled the leakage rate at the limit level of ≤0.05ml/min. In the end, theWe helped the brand achieve a breakthrough of 99.7% in mass production of IPX8 rated products!
This case is a profound testimony to a truth:The reliability of waterproof performance not only comes from the sophisticated design, but also relies on the guarantee of precise and rigorous testing methods.
Core logic of IP ratings
The IP code consists of two digits (e.g. IP68):
- First digit (0-6): The dust protection rating represents the ability of the device to resist penetration by solid foreign matter (such as dust); the higher the number, the greater the dust protection, with the highest rating being 6, which means "completely dustproof".
- Second digit (0-9): The waterproof rating represents the ability of the device to resist penetration of liquids (mainly water). The larger the number, the more waterproof it is, and the highest rating is 9 (or 9K), which means "high-temperature and high-pressure jet waterproof".
Special attention: If one of the digits in the IP code is an "X", it means that the product is "not tested" or "not applicable to this class" in that category.For example, IPX8 indicates a waterproof rating of 8, but the dustproof rating was not tested.
Fourth, the common waterproof grade details and comparison
1. IPX7: "Basic insurance" for short-term water immersion
- (an official) standard: 1 meter water depth for 30 minutes without water ingress.
- application scenario: Daily splash-proof cell phone, Bluetooth headset.
- Detection Difficulties: Need to simulate static water pressure, Precision Engineering uses positive (negative) pressure method to detect, through the pressure attenuation value to determine the sealing.
2. IPX8: The "Flexible Game" of Depth and Time
- (an official) standard: Manufacturer's customization (usually ≥ 1 meter, time > 30 minutes), such as smartwatches are often labeled "50 meters waterproof".
- Detecting the key: Consultation with the customer on test conditions is required, and Precision Engineering supports customized airtightness test fixtures (up to 100 meters water depth simulation).
3. IP67: The "King of Price/Performance" for Dust and Water Resistance
- (an official) standard: Fully dustproof (level 6) + waterproof to a depth of 1 meter for 30 minutes (level 7).
- typical application: Outdoor lighting equipment, industrial sensors.
- Testing ProgramDust test (8-hour sandbox test) followed by IPX7 waterproofing.
4. IP68: the "industry benchmark" for all-round protection.
- (an official) standard: Full dust protection (level 6) + continuous immersion protection (depth and duration defined by the manufacturer, typically ≥ 1.5 meters/1 hour).
- High-end scenarios: Smartphones, diving equipment, military communications equipment.
- Testing equipment: The Precision Tech Multi-Channel Airtightness Tester can test up to 10 products simultaneously, increasing efficiency by 800%.
5. IP69K: The Ultimate Armor for Extreme Environments
- (an official) standardDust protection level 6 + withstand 80℃ high temperature water column (14-16L/min, pressure 8-10MPa).
- Industrial rigidity: Automobile engine parts, food processing equipment.
- Detection ChallengesFor high-temperature and high-pressure environments, Precision Engineering has customized stainless steel test chambers with a pressure resistance value of 3MPa.
V.Air tightness testing equipmentCore rules of selection
dazzling array ofAir tightness testing equipmentHow to quickly choose the right one? Precision Industrial Technology refines the five-step core law, to help you hit the nail on the head, efficient selection:
1. Clarify the criteria (targeting):
- Core:The first step is to define the IP rating or air tightness specification that the product needs to meet. Different standards require different equipment.
- Precision Engineering suggests:Accurately benchmark product standards to avoid blind selection. For example, IP68 and IPX7 devices have very different requirements.
2. Matching parameters (hard indicators):
- Core:Focus on two key parameters: pressure range and leakage rate. Pressure range: IP67: at least 10kPa, IP69K: ≥2MPa. Choose according to your needs, not the bigger the better.
- Leakage rate:Consumer electronics ≤ 0.5 ml/min, medical equipment ≤ 0.01 ml/min. the higher the precision, the stronger the performance of the equipment.
- Precision Engineering Advantage:The accuracy of the detector is as high as 0.001ml/min or 0.1Pa to meet demanding standards.
3. Fixture customization (efficient fitting):
- Core:Customized fixtures are the key to improving inspection efficiency and accuracy.
- Precision Engineering Advantage:3D scanning and reverse engineering of customized fixtures to ensure zero clearance fit to the product. Quick locking design to improve mass production efficiency.
4. Estimated capacity (mass production guarantee):
- Core:Select multi-station/multi-channel equipment according to capacity requirements.
- Precision Engineering Program:Provide multi-station, multi-channel detector, flexible expansion, and highly effective response to the needs of mass production.
5. Validation cycle (reliable data):
- Core:Regular calibration is key to guaranteeing the long-term reliability of your equipment.
