November 17, 2023


What Are We Talking About?

Hey there! So you’ve probably seen these cryptic “IP” ratings thrown around on gadgets and equipment, right? IP65, IP67, IP what now? It’s like alphabet soup but for tech specs. Relax, we’re about to break it all down. By the end of this guide, you’ll not only understand what these IP ratings mean but also which one is the best fit for your needs. Trust me, it’s gonna be a game-changer when you’re picking out your next waterproof gizmo.

Why Waterproof Ratings Matter

The Real-World Impact

Let’s get real. Your devices and equipment aren’t just chilling in a cozy living room all day. They get exposed to rain, spills, maybe even a dive into a puddle if you’re not careful. That’s why these waterproof ratings are super important. They’re not just random numbers; they’re your gear’s armor against the messiness of life.

Say you work outdoors or love hiking, a higher IP rating is your buddy. It ensures your gadget can take a dunk or withstand a downpour and keep on ticking. On the flip side, if you’re all about that indoor life, you might not need to go for the highest rating out there. Why pay more for protection you don’t need, right?

In short, understanding waterproof ratings is like knowing your car’s mileage. It helps you make smarter choices and save some bucks in the long run. So yeah, it’s kind of a big deal.

Breaking Down the IP Rating System

What Do The Numbers Mean?

Alright, so you’ve seen these IP ratings like IP65, IP67, or whatever. What’s up with that? The “IP” stands for “Ingress Protection,” but let’s not get bogged down by jargon. Here’s the skinny: the first digit after IP tells you how good it is at keeping out solid stuff like dust. The scale usually goes from 0 to 6. Zero means no protection, and 6 means it’s a dust fortress. Simple, right?

Understanding the Second Digit

Now, the second digit is all about liquids, usually rated from 0 to 8. Zero is like that friend who melts in the rain. Don’t take ’em outside. An 8, though? That’s your die-hard buddy who’d join you in a rain dance and not skip a beat.

So, if you see something rated IP68, know that it’s pretty much a superhero: maximum defense against dust and can take a long swim without a hiccup. But remember, not all heroes wear capes—some come with IP ratings.

Most Common IP Ratings for Waterproofing


Let’s start with the IP65. Good for indoor spots, it can keep dust at bay and handle a splash or two. Think about this one if your gear’s indoors but sometimes faces a little mist or a light spray of water. It’s not the king of the jungle, but it gets the job done in most cozy indoor settings.


Step it up a notch, and you’ve got IP66. This one’s a bit more rugged. Still good on the dust front, but it also doesn’t mind a strong squirt of water from any direction. You’ll see this bad boy in places that need something tough but not Navy SEAL tough.


Now, meet IP67. It’s not messing around. The dust can’t get in, and it can even take a short swim, up to 30 minutes in water that’s about a meter deep. If you’re into outdoor activities or work in an environment that sometimes gets wet, IP67 won’t let you down.


And here’s the superstar, IP68. When it comes to solid and liquid ingress, it’s a brick wall. Dust? What dust? Water? Bring it on. It can even go for a longer, deeper swim than IP67. If you work in some really tough conditions or just want the best of the best, IP68 is your guy.

So, now you know. Whether you’re splurging on new gear or picking out enclosures for your workspace, check out those IP ratings. Trust me, it makes a difference.

How to Choose the Best Rating for You

Assess Your Needs

First things first, take a good look at where you’ll be using the gear. Is it a calm indoor setting or a tough-as-nails outdoor environment? What are you really up against? Dust? Rain? A mini-tsunami? Your needs will guide your choice. For instance, if you’re in a dusty workshop but not expecting a flood, you probably don’t need the top-tier IP68. An IP65 or IP66 should do the trick.

Don't Overkill

Look, I get it. The idea of having the best protection sounds awesome. But let’s be real; you don’t wear a raincoat on a sunny day, right? Going overboard can cost you more money for features you’ll never use. For example, if you’re mostly dealing with dust and occasional light sprays, an IP68 might be overkill. You’d be paying for submarine-level waterproofing when you’re not even going paddling. So, get what suits your needs, not what sounds the coolest.

Remember, the goal is to match the rating to your actual lifestyle or work conditions. That way, you’re not throwing money away or skimping on the protection you need.


Final Thoughts and Tips

Alright, you’re now clued up on IP waterproof ratings. Just remember, the ‘best’ rating depends on your specific needs.

Know Your Needs: Where you’ll use the product matters. Don’t guess, assess!

Read Up: Double-check what the rating actually covers before buying.

Think Ahead: Consider future needs; sometimes it’s smarter to go a bit higher on the rating.


What IP rating is 100% waterproof?

No IP rating guarantees 100% waterproofing, but IP68 is currently one of the highest levels of water protection offered. IP68 rated devices are deemed “dust-tight” and can be submerged in more than one meter of water for a certain period, typically 30 minutes. However, it’s essential to remember that “waterproof” can often refer to being able to resist water to some degree, not necessarily being entirely impermeable to water under all conditions.

Which is better IP67 or IP68?

IP68 is superior to IP67 in terms of water and dust resistance. While both ratings ensure total dust protection, the key difference lies in their water resistance. An IP67-rated device can be submerged in water up to 1 meter deep for up to 30 minutes. In contrast, an IP68-rated device can be submerged in water beyond 1 meter (the exact depth can vary between manufacturers) for a specified period, often around 30 minutes.

Is IP69K better than IP68?

Yes, IP69K provides a higher level of protection than IP68. While IP68 ensures dust tightness and water resistance for submersions beyond 1 meter, IP69K offers protection against high-pressure, high-temperature water jets. IP69K is a rating often associated with equipment that needs to be cleaned and sanitized with high-pressure hot water, making it suitable for environments like food processing plants where hygiene and cleanliness are critical.
