Table of Contents

IP code is important when purchasing digital products and electronic devices. Many brands have mentioned the concept of IP67 and IP68 in product launches to validate the performance of their products, but what is the actual meaning of these two terms and what is the difference between IP67 vs IP68?

IP, or Ingress Protection, is a rating system that indicates how well a device is protected against dust and water. the first digit of the IPXx rating, X, refers to protection against solid particles, and the second digit of the rating, x, refers to protection against liquid.

In this detailed IP68 vs IP67 comparison guide, we will give you a detailed overview of their importance and where the main differences lie.

What Is the IPXx?

The IP (ingress protection) is a standard set by the International Electrotechnical Commission to evaluate the protection and durability standards of electrical equipment against dust and water.

The IP protection rating consists of two numbers, the first number X indicating the dust protection rating and the second number x indicating the water resistance rating. The higher the number, the better the protection.

Waterproof rating (Second Digit)

  • IPX0: No protection.
  • IPX1: Protected against the vertical waterfall, preventing water droplets from falling in when the product is placed for indoor use.
  • IPX2: Protected against the tilted water flow, preventing continuous water penetration into the interior when the product is tilted up to 15°.
  • IPX3: Protected against water jets, such as rainwater, when the product is tilted at a maximum of 60°.
  • IPX4: Protection against splashing water, able to withstand water jets from all directions, simulating a rain splash situation.
  • IPX5: Protects against low-pressure jets of water with an inner diameter of 6.3mm from the nozzle.
  • IPX6: Protected against strong water jets, capable of withstanding strong water jets with an inner diameter of 12.5mm from the nozzle.
  • IPX7: Protection against temporary immersion, able to withstand submergence under water for a specified period and under pressure.
  • IPX8: Protection against continuous immersion, the device can be continuously submerged underwater and maintain normal operation.

 

IP67 Vs IP68 

 

IP67 :

An IP67  waterproof solar panel indicates that they are “dust-tight,” providing complete protection against the intrusion of dust, and are also capable of withstanding temporary immersion in water up to a depth of 1 meter (approximately 3.3 feet) for up to 30 minutes.

Solar panels with an IP67 rating are well-suited for environments where they might be exposed to rain, snow, or occasional submersion in water. They are commonly used in outdoor and marine applications.

IP68:

An IP68 rating offers an even higher level of protection than IP67. Solar panels with an IP68 rating are also “dust-tight” and can withstand immersion in water for an extended period, typically beyond 1 meter (3.3 feet) and for longer durations than IP67.

IP68-rated solar panels are ideal for applications where the panels will be continuously submerged in water or exposed to extremely wet conditions, such as in underwater solar installations, aquatic systems, or environments with heavy and prolonged rain.

According to the explanation of IPXx above, IP67 is both dustproof grade 6 and waterproof grade 7, i.e. Fully dustproof while temporary immersion will not affect normal use, and can withstand the pressure of being immersed in water for a specified time.  IP68 means that it is both dustproof to class 6 and waterproof to class 8, i.e. it is completely dustproof, and the device can be submerged underwater for extended periods and remain operational.

To conclude, the main difference between IP67 vs. IP68 is that IP68 products can remain undamaged underwater for longer periods, while IP67 allows the product to be waterproof only temporarily.

Why is IP67 vs IP68 So Important?

Waterproof solar panels with dust and waterproof ratings offer several key advantages:

Enhanced Safety Assurance: IPXX protection level testing ensures that the product remains resistant to dust and water exposure during usage, ensuring the safety of the product.

Prolonged Product Lifespan: The IPXX protection ratings are crucial in extending the product’s life. Exposure to dust and water can accelerate wear and aging, potentially shortening the product’s lifespan.

Elevated Product Quality: IPXX protection level testing acts as a quality benchmark, demonstrating that the manufacturing processes and materials used are of high standards. This, in turn, enhances the overall quality of the product.

Market Entry Compliance: Attaining protection level certification meets market entry standards and boosts the product’s competitiveness in the market. This certification becomes a crucial factor for consumers when comparing similar products.

Cost-Effective After-Sales: In the event of product failure, IPXX protection level testing helps identify the cause of the failure. Without such testing, diagnosing issues becomes challenging, leading to increased after-sales costs associated with product support and repairs.

In summary, the IP protection test serves as a comprehensive tool to verify and guarantee the dustproof and waterproof performance of a product. This not only enhances reliability and competitiveness but also fosters user trust. It is an indispensable testing tool throughout the product development and production process.
