Which is more waterproof: IP65 or IP67?

In the world of electronic devices, waterproof ratings play a crucial role in determining their suitability for different environments and applications. Two common ratings are IP65 and IP67, frequently highlighted when it comes to the waterproof capabilities of gadgets and equipment. But which one offers better protection against water ingress? In this article, we will delve into the technical aspects of both IP65 and IP67 ratings to find out.

Understanding IP Ratings

IP, an abbreviation for Ingress Protection, is a standard set by the International Electrotechnical Commission (IEC) to define the level of protection provided by enclosures and casings. The IP rating consists of two digits - the first indicating protection against solid particles while the second signifies resistance to liquid ingress.

Exploring IP65 Waterproof Rating

An IP65 rating is commonly encountered in rugged electronic devices and outdoor equipment due to its considerable water-resistant properties. The first digit, "6," signifies that it provides complete protection against dust and other solid particles. The second digit, "5," means it can withstand low-pressure water jets from any direction without harmful effects. While it may not be fully submersible, such as being dropped in water, it can handle various weather conditions and survive temporary exposure to rain or splashes.

Diving into IP67 Waterproof Rating

When it comes to greater water protection, the IP67 rating takes it up a notch. Similar to IP65, the first digit, "6," denotes dust-tight protection. However, the second digit, "7," indicates a higher tolerance for water immersion. An IP67-rated device can be submerged in up to one meter of water for 30 minutes without suffering damage. This makes it suitable for more extreme environments, including outdoor activities like swimming or snorkeling.

Differentiating Factors

While both IP65 and IP67 ratings offer substantial waterproof qualities, they have differences that suit various needs. If you require excellent protection against dust and low-pressure water jets, IP65 is sufficient. It can withstand rain, moisture, and moderate splashes. IP67, on the other hand, provides an additional advantage of temporary immersion in water, making it ideal for situations where there is a higher chance of complete submersion.

It is crucial to understand that the IP rating only pertains to water protection and does not reflect overall durability or ruggedness. Other factors, such as impact resistance or chemical exposure, should also be considered when selecting suitable equipment for specific applications.

In conclusion, whether IP65 or IP67 is better in terms of waterproofing depends on the requirements of the intended use. Both ratings offer varying levels of protection against dust and water, with IP67 providing enhanced submersion capabilities. Understanding these distinctions allows individuals to make informed decisions when choosing devices that can withstand the demands of their environment.
