IPX3-test
Electronic devices and enclosures are often exposed to moisture and water under varying conditions. Think of outdoor lighting enduring rainfall, industrial control panels operating in humid environments, or automotive electronics exposed to splashing water. The IPX3 test is a critical Ingress Protection (IP) assessment used to evaluate whether a product can resist spraying water at angles up to 60°.
Internationally recognized standard
At Sebert Group, we conduct IPX3 testing in accordance with the internationally recognized IEC 60529 standard. This ensures that your product meets the necessary certification and quality requirements — increasing reliability and extending lifespan.
How Does the IPX3 Test Work?
The IPX3 test assesses whether a product can withstand water sprayed at an angle of up to 60° from vertical. It extends beyond the scope of IPX1 and IPX2, which only measure protection against dripping water.
To simulate realistic environmental conditions, the test is carried out using either an oscillating spray arc or a spray nozzle:
After testing, the product is inspected to determine whether water ingress has occurred and whether functionality remains unaffected.
Oscillating Arc Method:
-
Water flow: 2.17 L/min (±5%)
-
Test duration: 10 minutes
-
Arc rotation: 60° from vertical
-
Specimen rotated 90° after 5 minutes
Specimen rotated 90° after 5 minutes
-
Water flow: 10 L/min (±5%)
-
Test time: 1 minute per m², minimum of 5 minutes
-
Spray angle: Up to 60° from vertical, covering all practical sides
-
Shield used: Yes
Test Chamber Specifications
Our testing facilities are equipped with advanced equipment that guarantees accurate and repeatable test results. Key chamber specifications include:
-
Usable internal test space: 400 x 400 x 500 mm
-
Water flow: 0.07 L/min (±5%) × 31 spray nozzles
Spray Nozzle Setup:
External test space: Unlimited
Water volume: 10 L/min (±5%)
Water pressure: 0.05 to 0.15 MPa
These configurations allow us to simulate various real-world testing scenarios with precision.
Why is the IPX3 Test Important?
IPX3 classification is essential for products regularly exposed to spraying water or rain, including:
While IPX3-certified products are not fully waterproof, they can resist light rain and sprayed water. For environments requiring protection against heavy rain or immersion, higher ratings such as IPX4 through IPX8 are recommended.
IPX3 classification is essential for products regularly exposed to spraying water or rain, including:
-
Outdoor lighting and street furniture, which must withstand rain exposure
-
Electronic enclosures and control panels in industrial or maritime environments
-
Vehicle technologies and transport systems, subject to splashing water
-
Medical equipment, which must endure cleaning and disinfection procedures
-
Household products like outdoor outlets and irrigation systems
Benefits of an IPX3-Tested Product
An IPX3-compliant product offers greater reliability thanks to enhanced moisture resistance, which contributes to a longer lifespan and reduced failure due to water ingress.
IPX3 testing can also help reduce warranty and service costs, improve customer satisfaction, and strengthen your product's position in the market. In industries where certification is key — such as electronics and automotive — IPX3 testing is often a decisive factor during product development and quality control.
