IPX44-test
Protection Against Water Spray and Object Intrusion – IEC 60529
Do you need to demonstrate that your enclosure is resistant to water spray and intrusion by objects smaller than 1 mm? An IP44 test confirms whether your product meets these requirements.
Sebert Group conducts these tests in full compliance with international standard IEC 60529, which classifies the level of protection provided by enclosures against solid objects, dust, and water ingress.
IP44 is a commonly requested rating for electrical enclosures used in damp indoor spaces or outdoor environments.
What does IP44 Mean?
An IP rating consists of two digits.
The first digit (4) refers to protection against solid objects such as tools or wires (IP4X). In this test, a 1 mm diameter steel probe is used to check that no access is possible to live or hazardous parts inside the enclosure.
The second digit (4) indicates protection against water splashing from any direction (IPX4).
Together, these tests are essential to ensuring the safety and reliability of electrical equipment in environments exposed to moisture or airborne debris.
IPX4 – Protection against water spray
To assess water resistance under IPX4, Sebert Group performs two standardized methods as defined in IEC 60529, section 14.2.4:
Oscillating spray method (for smaller products):
The product is placed on a perforated turntable under a spray arc with 31 nozzles, which oscillates to simulate water spray from all directions. The test lasts 5 minutes per direction (total 10 minutes), with a flow rate of approximately 2.17 liters per minute.
Handheld spray nozzle method (for larger products):
Water is sprayed from a handheld nozzle at a pressure of 0.05 to 0.15 MPa, from all practical angles. The spray delivers 10 liters per minute, for at least 5 minutes or 1 minute per square meter of surface area.
In both methods, the product must remain free from water ingress that would result in damage or an unacceptable level of penetration as defined by the standard. Products are mounted on a wall or platform, depending on their intended use orientation.
IP4X – Protection against solid objects
The IP4X test uses a standardized test probe: a 1 mm steel wire, which is pressed with a force of 1 newton against all accessible openings of the enclosure. The goal is to confirm that no part of the probe can reach any potentially hazardous internal components.
If the product is tested without internal components installed, there must be no access to parts that could pose a danger when fully assembled. To pass the test without remarks, the probe must not penetrate the enclosure — not even partially — unless a functional internal barrier qualifies as the effective enclosure.
Our testing approach at Sebert Group
IP44 testing is always carried out in close consultation with the client, following a structured procedure and in the product’s normal operating position.
If the enclosure is tested empty, no water may enter during the IPX4 test that could lead to damage or dangerous conditions. Final inspection is performed in line with the applicable standards, any client-specific requirements, and, where possible, in the presence of the client.
You will receive a clear and detailed test report outlining the results.
A reliable and standardized testing environment
Our testing method has been approved by the technical committee of ElaadNL. We conduct all tests in accordance with current international standards. With years of experience in mechanical and climatic testing, we offer not only accurate results, but also practical support throughout the entire testing process — along with clear, comprehensive test reports.
