What is IP68 Certification?
In the world of industrial and marine equipment, IP68 certification is a gold standard for durability and reliability, especially in environments where exposure to water, dust, and debris is a constant threat. But what exactly does IP68 mean, and why is it so critical for marine applications? Let’s break it down.
IP68 Standards
The term “IP” stands for Ingress Protection, a classification system defined by the International Electrotechnical Commission (IEC) to rate the degree of protection provided by enclosures around electrical equipment. The IP rating consists of two digits, each representing a specific level of protection:
- First Digit “6”: Dustproof (Complete Protection)
- The first digit in the IP68 rating indicates the level of protection against solid objects, such as dust and debris.
- A rating of “6” means the equipment is completely dustproof. No dust or particulate matter can penetrate the enclosure, ensuring uninterrupted operation even in dusty or sandy environments, such as coastal areas or offshore drilling sites.
- Second Digit “8”: Waterproof (Submersion Beyond 1 Meter)
- The second digit refers to the level of protection against liquids, particularly water.
- A rating of “8” signifies that the equipment is waterproof and can withstand continuous submersion in water beyond 1 meter. The exact depth and duration are specified by the manufacturer, making IP68-certified devices ideal for marine and underwater applications.
Comparison to Lower Ratings (e.g., IP67)
While IP68 is the highest standard for waterproofing, other ratings like IP67 are also commonly used. However, there are significant differences that make IP68 superior for marine environments:
- IP67:
- Dustproof (first digit “6”).
- Waterproof for temporary submersion up to 1 meter for 30 minutes.
- Suitable for environments with occasional water exposure but not prolonged submersion.
- IP68:
- Dustproof (first digit “6”).
- Waterproof for continuous submersion beyond 1 meter, with depth and duration specified by the manufacturer.
- Designed for harsh, long-term underwater use, making it the preferred choice for marine applications.
For industries like offshore drilling, subsea robotics, and naval systems, IP68 certification ensures that equipment can operate reliably even under extreme conditions, such as deep-sea exploration or prolonged exposure to high-pressure water.
Testing Criteria for IP68 Certification
Achieving IP68 certification is no small feat. It requires rigorous testing to ensure the equipment can withstand the harshest conditions. Here’s what the testing process typically involves:
- Dustproof Testing:
- The equipment is exposed to fine dust particles in a controlled environment.
- To achieve a “6” rating, no dust must penetrate the enclosure after 8 hours of testing.
- Waterproof Testing:
- Submersion Testing: The equipment is submerged in water at a depth specified by the manufacturer (typically beyond 1 meter) for a prolonged period (often 24 hours or more).
- Pressure Resistance: The device is tested under high-pressure water jets to simulate extreme marine conditions.
- Durability Evaluations: The equipment is subjected to thermal cycling, vibration, and mechanical stress to ensure long-term reliability.
Only after passing these stringent tests can a product be labeled as IP68-certified waterproof.
Why IP68 Certification Matters for Marine Applications
For marine environments, where equipment is constantly exposed to saltwater, high pressure, and abrasive particles, IP68 certification is not just a luxury—it’s a necessity. Here’s why:
- Saltwater Resistance: IP68-certified slip rings are built with corrosion-resistant materials, such as marine-grade stainless steel, to withstand saltwater exposure.
- Long-Term Reliability: The rigorous testing ensures that the equipment can operate flawlessly even after prolonged submersion.

Why Marine Applications Demand IP68-Certified Slip Rings
Marine environments present one of the most extreme operating conditions for any type of electrical or mechanical equipment. Factors like corrosive saltwater, high-pressure water exposure, and constant humidity stress the durability and functionality of components like slip rings. In these conditions, ensuring that the equipment operates reliably without failure is essential, which is why IP68-certified slip rings are necessary for such demanding applications. These slip rings are designed to withstand harsh conditions, offering the protection needed for continuous, trouble-free operation.
Key Challenges in Marine Environments
Saltwater Corrosion Resistance
Saltwater is known for its aggressive and corrosive nature. It is a major cause of wear and tear on metals and electrical components in marine environments. The salt in seawater accelerates the electrochemical process of corrosion, leading to rusting, pitting, and eventual failure of materials. When exposed to saltwater, metals lose their strength and electrical conductivity, which can severely compromise the functionality of slip rings.
For marine applications such as offshore drilling, subsea robotics, and naval systems, the corrosion caused by saltwater exposure can be devastating. Non-sealed slip rings are at risk of degradation, leading to the potential breakdown of internal electrical components. IP68-certified slip rings are designed to offer exceptional protection against saltwater corrosion. These slip rings are equipped with advanced sealing technologies and corrosion-resistant materials that prevent saltwater from penetrating the internal components. By creating a watertight barrier, IP68 slip rings ensure the electrical system continues to perform reliably, despite the harsh and corrosive environment.
High-Pressure Water Jets (e.g., Underwater Equipment, Wave Impacts)
Marine environments subject equipment to high-pressure water, particularly in subsea applications or during offshore operations. Whether it’s the powerful water currents encountered by underwater robotics, the force of waves battering equipment on the surface, or the impact of high-pressure jets used for cleaning or operating equipment, the stress of water exposure is immense. Non-waterproof slip rings exposed to high-pressure water can experience water ingress, which disrupts electrical connections and causes equipment failure.
For underwater equipment like ROVs (remotely operated vehicles) or subsea drilling machinery, the constant exposure to high-pressure water increases the risk of damaging delicate components. With IP68 certification, slip rings are specifically engineered to endure pressure without allowing water to seep in. The IP68 certification assures that slip rings will remain functional even under prolonged exposure to submerged conditions, providing reliable electrical transmission in harsh underwater conditions. The rigorous sealing and precision construction of IP68 slip rings ensure their effectiveness in maintaining operational integrity in high-pressure environments.
Long-Term Reliability in Submerged or Humid Conditions
Marine systems often operate for extended periods submerged underwater or exposed to highly humid conditions. Subsea equipment, for instance, may spend days, weeks, or even months operating under the ocean’s surface, where the risks of water ingress and environmental degradation are high. Over time, humidity, moisture, and exposure to seawater can weaken the components, leading to rust, degradation of the internal electronics, and ultimately, system failure.
Non-IP68 slip rings are more susceptible to damage from prolonged exposure to moisture. Even slight ingress of water or condensation inside a slip ring can cause corrosion or short-circuiting of the electrical components, leading to catastrophic failures. IP68-certified slip rings, on the other hand, are specifically designed to remain functional in submerged conditions or humid environments, ensuring the smooth transmission of power and data even under these extreme conditions. The long-term reliability of IP68 slip rings ensures that marine systems can continue to operate efficiently without the risk of unexpected downtime or repair costs.
Consequences of Non-Compliant Slip Rings
Using slip rings that do not meet the necessary waterproofing standards, such as IP68, can lead to severe consequences for marine operations. These components are critical for ensuring uninterrupted power and data transmission, and any malfunction due to inadequate waterproofing can disrupt operations, damage equipment, and put personnel at risk. Below are the key consequences of using non-compliant slip rings in marine applications:
System Failures
One of the most immediate and disruptive consequences of using non-IP68-certified slip rings is system failure. When water or dust gets into a slip ring that is not adequately sealed, it can lead to short circuits or signal interruptions. These failures are particularly problematic in critical applications such as offshore oil rigs, subsea robotics, or naval vessels, where the equipment must perform continuously without interruption. In these high-risk environments, the failure of even one component can lead to total system failure, causing operational halts and the need for costly repairs.
Moreover, such failures often happen unexpectedly, causing significant delays and operational downtime. Equipment that is exposed to saltwater, high-pressure jets, or long-term humidity without proper sealing becomes vulnerable to corrosion and electrical malfunction, compromising the entire system’s performance. Non-compliant slip rings lack the durability needed to maintain continuous operations under extreme conditions, leading to increased risks of failure.
Safety Risks
Marine environments, especially in offshore drilling and subsea operations, can be hazardous places to work. Equipment failure caused by inadequate waterproofing can result in severe safety risks. For example, water entering the internal components of a slip ring can cause electrical shorts, potentially leading to electrical fires or explosions in volatile environments like offshore rigs. Additionally, if a failure occurs in a critical system like a subsea robot or drilling machinery, it may leave operators stranded or unable to control the equipment, leading to potential injury or loss of life.
Further, safety is compromised when non-compliant slip rings cause failures in equipment like navigation systems, communication devices, or surveillance systems on naval vessels. Inaccurate readings or loss of control over critical systems can lead to accidents, putting both personnel and the environment at significant risk.
Costly Downtime
In marine industries, downtime due to equipment failure is extremely costly. Whether it’s an offshore drilling rig, subsea robotics, or naval operations, every minute of downtime translates into significant financial loss. For instance, in offshore oil drilling, a single day of downtime can cost millions of dollars due to lost production, increased operational costs, and delayed project timelines.
Non-compliant slip rings that fail to withstand the harsh conditions of marine environments require frequent maintenance or replacement, which adds to the overall costs of operation. In addition, the process of identifying and repairing system failures caused by water or dust ingress can involve lengthy inspections and unplanned downtime, further exacerbating the financial impact.
The lack of long-term reliability in non-compliant slip rings increases the likelihood of frequent repairs and replacements, adding significant expenses to an already high-cost operation. When slip rings are IP68-certified, they help avoid this problem by providing long-term, trouble-free operation, reducing the need for costly repairs and preventing unexpected downtime.
IP68-certified slip rings are essential in marine applications due to the extreme challenges posed by saltwater corrosion, high-pressure water exposure, and the need for long-term reliability in submerged or humid conditions. Without this level of protection, systems are vulnerable to failure, safety risks, and costly downtime. For any marine operation, using IP68-certified slip rings is crucial to ensure continuous, reliable performance under even the most demanding conditions, protecting both the equipment and the people who depend on it.

FAQs about IP68 Waterproof Slip Ring Marine Certification
Q： What is the highest slip rating?
The highest slip rating for a slip ring typically corresponds to its ingress protection (IP) rating, which determines how resistant the slip ring is to water and dust ingress. The IP68 rating is considered one of the highest slip ratings and is commonly used in environments where equipment is exposed to harsh conditions, such as underwater or in high-pressure environments. An IP68 slip ring can withstand continuous submersion in water beyond 1 meter in depth, and it also offers complete protection against dust ingress. This high rating ensures that the slip ring can perform in environments exposed to elements like saltwater, high humidity, and debris without compromising electrical or data transmission capabilities.
It’s important to note that the “slip rating” itself refers to how much a slip ring can operate under certain conditions without failure. For the highest level of durability and reliability, slip rings with IP68 ratings are often used in marine systems, offshore oil drilling equipment, subsea robotics, and other applications where water and dust resistance is crucial. The rating guarantees the equipment will continue to function in harsh conditions, reducing the risk of failure and ensuring long-term operational reliability.
Q： What is the life expectancy of a slip ring?
The life expectancy of a slip ring depends on several factors, including the operating environment, usage frequency, and maintenance practices. On average, a slip ring can last anywhere from 1,000 to 10,000 hours of continuous operation. However, certain types of slip rings designed for more rugged environments may have a lifespan that extends up to 20,000 hours or more, depending on the materials used and the quality of the seals and electrical contacts.
Several key factors influence the life expectancy of a slip ring:
- Environmental Conditions: Slip rings exposed to extreme temperatures, humidity, or corrosive environments may experience a shorter lifespan. IP-rated slip rings, such as those with IP68 certifications, are designed to withstand such conditions, but extreme environments may still cause wear over time.

Q： What is the difference between a split ring and a slip ring?
A split ring and a slip ring are both used in electrical and mechanical applications, but they differ in their design and functionality.
Split Ring: A split ring is a mechanical device typically used in DC motors and other applications where electrical current must be transmitted to a rotating component. It is a metal ring that is split into two halves, which are positioned to create a contact between the rotating part and the stationary brushes. The split ring functions as a commutator, reversing the direction of the current as the rotor turns. The split ring is often used in applications where the direction of current flow needs to change periodically, such as in motors.
Slip Ring: A slip ring is an electrical component that allows continuous transmission of power or data from a stationary to a rotating part without interruption. Unlike split rings, slip rings use brushes that maintain contact with the conductive rings, ensuring that electrical signals or power are transmitted seamlessly in rotating systems. Slip rings are commonly used in applications such as wind turbines, radar systems, and industrial equipment.
The primary difference is that a split ring is typically used in DC motors for commutation, whereas a slip ring is used in various rotating machinery to provide continuous electrical connection without interruption.
Q： What is the disadvantage of slip ring motor?
The primary disadvantage of slip ring motors lies in their complexity and maintenance requirements. Some of the challenges associated with slip ring motors include:
Maintenance: Slip ring motors require more frequent maintenance than squirrel cage motors due to the brushes and slip rings. These components wear out over time and need to be replaced regularly to ensure proper operation.
Cost: Slip ring motors tend to be more expensive than squirrel cage motors, both in terms of initial purchase price and maintenance costs. The need for additional components like slip rings and brushes increases the overall cost.
Size and Weight: Slip ring motors are generally larger and heavier than their squirrel cage counterparts. This can make them less suitable for applications where space is limited or where weight is a critical factor.
Brush Wear: The brushes in slip ring motors make physical contact with the slip rings, which causes wear and tear. This leads to increased maintenance needs, as worn-out brushes can cause power loss, reduced efficiency, and even damage to the slip rings.
Despite these drawbacks, slip ring motors are still used in applications where high starting torque and variable speed control are necessary, such as in large industrial machinery and crushers.
