Ingress Protection (IP) Testing
Professional Ingress Protection Testing by engineers who help you troubleshoot, optimize, and certify your products.
IP & NEMA Testing: Don’t Just Test. Validate with Confidence.
At Castle Compliance, we understand that an Ingress Protection (IP) rating is more than just a checkbox—it is a promise of reliability to your customers. Whether you are launching a consumer wearable, a rugged military device, or an industrial enclosure, our laboratory provides the precise environmental simulation you need to prove your product can survive the elements.
Unlike “pass/fail” test houses that rely solely on technicians, we operate as an extension of your engineering team. Our Ingress Protection (IP) testing is conducted by experienced, degreed engineers who understand seal integrity, material properties, and enclosure design. We operate in strict compliance with ISO 17025 Quality Management Systems, ensuring every test is repeatable, documented, and performed using NIST-traceable calibrated equipment.

The Castle Difference: Why Engineers Choose Us
We know the frustrations of working with large, bureaucratic Ingress Protection (IP) testing labs: slow quotes, silent failures, and vague reports. We built Castle Compliance to solve those pain points.
1. Degreed Engineers, Not Just Technicians
Ingress Protection (IP) testing requires more than pointing a nozzle. It requires understanding hydrostatic pressure, thermal expansion, and gasket compression. Our test engineers are technical experts who can offer guidance on torque specs, seal materials, and enclosure design before the test begins.
2. Consultative Troubleshooting
A failure in the lab is better than a failure in the field—but only if you know why it happened.
- Real-time Feedback: If we detect a leak early in the IP test, we stop and notify you immediately.
- Failure Analysis: We utilize UV-reactive dyes and localized pressure testing to trace the exact path of water ingress, helping you pinpoint the weak spot in your design.
3. Quality & Traceability
We maintain a rigorous Quality Management System (QMS) compliant with ISO 17025 standards. All instrumentation used in our testing—from pressure gauges to flow meters—is calibrated with NIST traceability, ensuring your test data is accurate and defensible.
Understanding the IP Code
The IP Code (also known as Ingress Protection or International Protection) helps classify the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures.
- First Numeral (Solids): Ranges from 0 (No protection) to 6 (Dust-tight).
- Second Numeral (Liquids): Ranges from 0 (No protection) to 9K (High-pressure steam).
The most common ratings we test and certify include IP55, IP65, IP66, IP67, and IP69K. Other frequently used ratings we test and certify include IP22, IP44, IP54, and IP68. However, we can cover all the IP code ratings in our laboratory.
Frequently Asked Questions (FAQs)
Yes. Because many test methods overlap (such as the hose-down test for IP66 and NEMA 4X), we can often execute a single test plan that satisfies the technical requirements of both IEC 60529 and NEMA 250 standards. This saves you significant time and budget compared to running two separate programs.
We view Ingress Protection testing as an iterative process. If a unit fails, we provide detailed observations on the location and volume of ingress. We offer flexible re-test options to get you back in the lab quickly once you have implemented a design fix.
“Waterproof” is a marketing term, not an engineering one. The IEC 60529 standard allows for some water ingress provided it does not “interfere with satisfactory operation” or reach live parts. We work with you upfront to define your specific Acceptance Criteria—whether that means zero drops allowed or “managed ingress” away from critical components.
