What Are IP65, IP66, IP67, and IP68? – Understanding International Protection Ratings

When selecting outdoor lighting or electronic devices, you might notice numbers like IP65, IP66, IP67, or IP68 in the product descriptions. But what do these numbers mean? How do they affect the product's use? This article provides an in-depth look at these protection ratings to help you make a more informed decision when choosing equipment.

What is the IP Rating?

"IP" stands for "Ingress Protection," a standard set by the International Electrotechnical Commission (IEC) to assess a device's resistance to solid objects (like dust) and liquids (like water). The IP rating is presented as "IP" followed by two numbers. The first number represents dust protection, while the second indicates water protection.

First Digit: Dust Protection Rating

  • 0: No protection
  • 1: Protects against solid objects larger than 50mm
  • 2: Protects against solid objects larger than 12.5mm
  • 3: Protects against solid objects larger than 2.5mm
  • 4: Protects against solid objects larger than 1mm
  • 5: Limited dust protection
  • 6: Complete dust protection, providing the highest level of dust resistanc

Second Digit: Water Protection Rating

  • 0: No protection
  • 1: Protection against vertically falling water droplets
  • 2: Protection against water droplets up to 15° from vertical
  • 3: Protection from sprayed water (light rain)
  • 4: Protection from splashing water
  • 5: Protection from low-pressure water jets
  • 6: Protection from high-pressure water jets
  • 7: Can withstand temporary immersion in water
  • 8: Suitable for continuous immersion in water

Common Protection Ratings Explained

  • IP65: Fully dustproof, with protection against low-pressure water jets. This type of device is suitable for outdoor use but is not designed for prolonged immersion.
  • IP66: Fully dustproof and resistant to high-pressure water jets, making it ideal for harsh outdoor conditions like heavy rain.
  • IP67: Fully dustproof and capable of withstanding temporary immersion (typically for 30 minutes at a depth of 1 meter). These devices are suitable for wet outdoor environments and brief submersion.
  • IP68: Fully dustproof and capable of continuous immersion in deeper water (specific depth and duration depending on the product). This rating is ideal for devices used underwater for extended periods.

How to Choose the Right Protection Rating?

Choosing the correct protection rating depends on your environment and needs. For example:

  • Outdoor Lighting: IP65 or IP66 lights can withstand outdoor dust and rain, but if there’s a chance of long-term submersion, consider IP67 or higher.
  • Pond or Pool Lighting: IP68 lights are recommended to ensure durability for continuous underwater operation.

In Summary

Understanding IP ratings can help you select suitable equipment, ensuring product safety and durability in various environments. By checking the protection rating when purchasing lighting or other electronic devices, you can extend the product's lifespan and enhance your experience. We hope this article clarifies IP ratings and serves as a helpful reference for your next purchase.
