IP65 vs. IP68: Understanding Waterproof Enclosure Ratings and Key Differences

The Meaning of IP Ratings and Their Significance

IP ratings indicate an enclosure’s level of water and dust protection. These ratings adhere to the IEC 60529 standard, which is used globally to assist consumers in selecting the appropriate equipment protection.

There are two numbers in the rating. The amount of dust that the enclosure keeps out is indicated by the first number (0–6). The amount of water it can withstand is indicated by the second number (0–8). The better the protection, the higher the numbers.

Selecting the appropriate enclosure for your task is made easier when you understand what an IP rating signifies. By selecting the appropriate amount of protection, you can prevent harm to your equipment whether it is indoors or out.

The IP65 Rating

For both indoor and outdoor electrical enclosures, the IP65 enclosure certification is widely used. Any enclosure with this grade offers dust-tight protection against all types of airborne dust and grime, as well as against unintentional contact with workers’ bodies or solid items like tools, because the first digit is 6.IP65 enclosures also guard against water intrusion from sources up to and including low-pressure nozzle jets because the second digit is 5. Additionally, an IP65 enclosure will guard against moist weather conditions including misting and rain as well as minor forms of water intrusion like splashing or dripping water.

The IP68 Rating

The IP68 enclosure classification is only given to enclosures that provide the strongest defence against all types of water and solid intrusion. Similar to the IP65 certification, the initial digit (6) denotes complete protection from dust intrusion. It also offers protection against water infiltration from complete submersion, including extended submersion in at least a metre of water, according to its second digit (8). Additionally, it provides protection against rain, sleet, and snow, as well as protection from high-pressure water jets, which are features of lower IP ratings. Because of this, it is the hardest IP enclosure rating and a top option for applications that need exceptional water resistance against submersion, wash-downs, or weather.

IP65 vs IP68: what’s the difference

Water-Resistant

Herein is the true distinction. Light moisture exposure, such as rain, mist, or low-pressure water jets, is what IP65 is made for. It works well both indoors and outside under cover.

IP68, on the other hand, is designed for significant water protection. Because it can withstand submersion in water, it is perfect for washdowns, moist settings, and even underwater applications. IP68 is a stronger option if water is a major concern.

Dust Defence

Both IP65 and IP68 provide a high degree of dust protection. They are completely sealed against dust and solid particles, preventing everything from small debris to unintentional touch, according to the “6” rating. In this regard, there is no distinction between the two; they are both great options for dusty settings.

Considerations for Cost and Budget

Because IP65 enclosures are more reasonably priced, they are a wise choice for many common scenarios where minimal water and dust protection is sufficient.

Although IP68 enclosures are more expensive, they offer superior protection for demanding or important environments. The additional expense can be worthwhile if your application requires continuous exposure to water.

How to Choose Between IP65 and IP68

Examine Your Environment

Consider your equipment’s intended function first. Will it be exposed to outside elements like dust or rain, or will it be placed within with little exposure to water?

IP65 is sometimes sufficient if there are only minor dust or splashes and the region is largely dry. However, IP68 is a safer option if your system is subjected to excessive humidity, frequent washdowns, or complete exposure to the weather.

Don’t Be Too Specific

It’s simple to want the best safety possible, but sometimes that means spending money on items you don’t really require. Conversely, avoid taking short cuts and endangering critical devices.

It’s important to match the rating to your actual circumstances, neither higher nor lower. You may balance cost, performance, and safety by selecting the appropriate level of protection.

Analyse Functionality and Risk

Next, consider the level of risk your equipment is exposed to. Is there a genuine possibility that it could be in water? Or is it more likely to occur occasionally?

Consider your budget as well. IP65 might save you money if your application doesn’t require complete waterproofing. However, investing with IP68 might be worthwhile for crucial systems that must always function.

Comparison with Other IP Ratings

IP44 vs. IP65

The IP44 classification provides rudimentary defence against water and solid objects. The first number, “4,” denotes defence against solid objects bigger than one millimetre. The majority of cables and tiny tools fall under this. The second number, “4,” denotes defence against water splashes coming from any angle.

On the other hand, the IP65 classification offers total dust protection. The first number, “6,” guarantees that the enclosure is free of dust particles. Resistance against low-pressure water jets from any direction is ensured by the second number, “5.” As a result, items with an IP65 rating are more suited for challenging conditions.

IP54 vs. IP65

The IP54 classification provides defence against splashes of water. The second number, “4,” indicates that water splashes from any direction can be tolerated by the enclosure. This degree of protection is appropriate for both mild outdoor and interior environments.

The IP65 grade offers defence against water jets. The second number, “5,” guarantees that low-pressure water jets from any direction can be withstood by the enclosure. Because of this, IP65-rated items are more durable for outdoor uses where exposure to water is likely.

IP67 vs. IP65

Devices with the IP67 classification can be temporarily submerged in water up to one metre deep for thirty minutes without suffering any negative consequences. IP65, on the other hand, can only withstand low-pressure water jets. As a result, IP67 is more suited for outdoor gadgets that could unintentionally submerge, such automobile and marine applications.

IP69 vs. IP65

The IP69 (or IP69K) classification is perfect for tough industrial settings like food processing, heavy machinery washdowns, or military-grade equipment because it provides protection against high-pressure, high-temperature water jets. IP69 offers noticeably better resistance to water incursion than IP65.
