What IP68 Means for Xtreme Heaters Customers

An IP68 rating is one of the highest levels of protection an enclosure can achieve under the International Electrotechnical Commission (IEC) 60529 standard. The first digit, "6," means the product is completely dust-tight, ensuring no particles can enter. The second digit, "8," indicates the device can withstand prolonged immersion in water under specific conditions without compromising its functionality or safety. Basically, an IP68 certified product is dust proof and water proof.

We recently contracted an independent certifications lab, Imanna Labs of Rockledge Florida, to test our line of boat/RV compartment heaters to the IP68 level of ingress protection. We are happy to report that the Xtreme Heaters passed with flying colors and are now the first and only heaters of their kind that hold this level of certification. This testing complements many other tests and certifications we have had performed on the heater, which you can read about here: https://www.xtremeheaters.com/pages/certifications

You might ask yourself why it's important for a heater to be dust proof and waterproof. Xtreme Heaters are used by boaters, RV'ers, inside of industrial enclosures, compressors and in backflow prevention devices. They meet the applicable industry standards for these applications. For some, a wet location rating is required, which IP68 exceeds.

In boats, heaters are exposed to high levels of moisture the majority of the time. They are also splashed when cleaning and occasionally dunked when a boat takes on water. In RV's, they are often placed in wet lockers full of plumbing that can leak, or under a skirted rig.

For Backflow Prevention enclosures, the ASSE 1060 standard applies and requires a heater rated for wet locations as the valved can purge to prevent backflow and flood the enclosure. Xtreme Heaters now meets the requirements of ASSE 1060.

How the Ingress Protection (IP) Tests Were Conducted

The 800W XXXL Heat Heater from Xtreme Heaters recently underwent a series of tests to determine its ability to keep out dust and water under extreme conditions. These tests, performed at IMANNA Laboratory, followed the IEC 60529 standards, which are widely used to rate the durability of enclosures against environmental factors. Here's a step-by-step breakdown of how the testing was prepared and executed.

1. Pre-Test Inspection
Before any testing begins, the heater is carefully examined. This step ensures the unit is free from damage or defects that could affect the test results. Technicians look for cracks, loose seals, or other flaws. Once it passes this visual inspection, the heater is considered ready for testing.

2. Dust Test (IP6X) Preparation
The dust test involves placing the heater inside a sealed chamber designed to mimic a very dusty environment. Here's how it works:

  • Talcum Powder: the IP6X dust is a high-quality talcum powder with a specific size of 45µm that is the standard for 60529 requirements.
    This powder easily passes through small gaps, making it perfect for testing dust resistance.
  • Circulation System: The chamber has a system to blow the powder around, ensuring it reaches all parts of the heater.
  • Test Duration: The heater stays in this environment for 8 hours, giving dust plenty of time to try and penetrate.

  Before dust was added.                                             After Dust added.                         

   


Once the test is complete, the heater is removed, cleaned off externally, and opened to check for any internal dust. If no dust is found inside, the heater passes the IP6X test.

3. Water Test (IPX8) Preparation
Next comes the water test, which simulates conditions far worse than a typical rainstorm. Here’s how it unfolds:
  • Water Immersion: The heater is placed in a large water tank and completely submerged.
  • Pressure Simulation: To simulate being underwater at a depth of 2 meters, the water pressure is increased to 2.84 PSI (pounds per square inch). This is important because deeper water exerts more pressure, forcing water into any weak points in the enclosure.
  • Timing: The heater remains submerged for 1 hour. This extended exposure ensures any potential leaks will have time to show themselves.


After the immersion, the heater is taken out, dried, and inspected. Any water inside could affect safety or performance, so technicians carefully examine the unit, looking for water on key components.

    

4. Post-Test Functionality Check
The final step is to see if the heater still works as intended. Power is applied, and the heater is tested in both heating and cooling modes. If it powers on and performs correctly, it confirms that any small amounts of water that might have entered didn’t harm its functionality or safety.

Why These Steps Matter
By following these rigorous procedures, manufacturers and testing labs can ensure that products like our Xtreme Heaters enclosure heaters are truly built to withstand harsh environments. The tests simulate real-world conditions, from dusty construction sites to marine environments where equipment might be submerged. Passing these tests means the heater can be trusted to protect its internal components, keeping you safe and your equipment running smoothly.

 

Important Safety Warning

Xtreme Heaters are waterproof, but electricity and water should never mix. Do not operate any electrical device, including Xtreme Heaters, if it’s in water.

If Submersion Happens:
Unplug immediately. Before using again, drain and dry the heater completely.

Stay Safe:
Always install your heater in a dry, enclosed area. If you suspect water exposure, disconnect power and check the device before use.
