IP68 is a high-level protection rating for devices, indicating their ability to withstand dust ingress and prolonged immersion in water under specific conditions.
What is IP68 Used For?
The IP68 rating is primarily used to ensure that devices are safeguarded against dust and water ingress. This is particularly important for equipment that operates in harsh environments where exposure to these elements is common.
Examples include:
Water meters
Water level sensors
Devices used in deep-water and marine applications
Outdoor electronic devices and systems
IP68: Dust and Water Protection
Dust Protection (6): The device is completely dust-tight, meaning no dust can enter the enclosure.
Water Protection (8): The device can withstand continuous immersion in water under conditions specified by the manufacturer, typically beyond 1 meter of depth and for prolonged periods.
This high level of protection ensures that the device remains functional even when submerged for extended durations, making it suitable for environments with constant exposure to water and dust.
Is IP68 Completely Waterproof?
Yes, devices with an IP68 rating are considered to be completely waterproof. They are designed to prevent water ingress even under prolonged immersion. However, "waterproof" in the context of IP68 means the device can handle specific conditions:
- Immersion Depth and Duration: Defined by the manufacturer, often exceeding 1 meter of depth.
- Pressure Conditions: The device can handle the pressure associated with the defined immersion depth.
Differences Between European and Chinese IP68 Standards
1. Standard Setting Bodies:
- Europe: The IP standards are set by the International Electrotechnical Commission (IEC), specifically IEC 60529.
- China: The IP standards are set by the Standardization Administration of China (SAC), specifically GB/T 4208-2017.
2. Standard Content:
- Dust Protection: Both European and Chinese standards agree that a rating of 6 means complete protection against dust ingress.
- Water Protection: Both standards agree that a rating of 8 means the device can withstand continuous immersion in water under specified conditions.
3. Testing Methods:
Europe: IEC 60529 outlines specific environmental conditions and procedures for testing, including water depth, duration, and temperature. Typically, the test for IP68 involves immersion beyond 1 meter, with specific conditions negotiated between the manufacturer and testing bodies.
China: GB/T 4208-2017 employs similar testing methodologies to ensure consistency with IEC 60529. It aims to provide comparable testing environments and conditions.
4. Implementation Details:
Europe: Different countries may have localized implementations based on IEC 60529, but the core content remains unchanged.
China: GB/T 4208-2017 is an equivalent adoption of IEC 60529, with possible adjustments to testing procedures to suit local requirements.
5. Certification and Recognition:
Europe: Devices need CE certification, which includes compliance with multiple standards, including IP ratings, to ensure market conformity within the EU.
China: Devices require CCC (China Compulsory Certification), which includes adherence to IP standards.
Conclusion
While the European IEC 60529 and Chinese GB/T 4208-2017 standards for IP68 share many similarities, ensuring consistent protection against dust and water ingress, some differences in implementation and testing specifics may exist. These differences generally do not impact the overall effectiveness of the protection but are important for manufacturers and testing bodies to consider. Devices with an IP68 rating are well-suited for environments with high exposure to water and dust, providing reliable protection and ensuring long-term functionality.
