What does IP6K9K Mean?

In industries like automotive and electronics, reliable waterproof testing is essential. LIB's IP6K/9K Water Spray Test Chambers replicate water exposure scenarios ranging from powerful linear jets (IPX6K) to high-pressure, high-temperature sprays (IPX9K), guaranteeing compliance with rigorous international standards such as IEC 60529 and ISO 20653. With precise control, durable materials, and user-friendly features, these chambers help you efficiently validate waterproof performance for a variety of applications.

As Allen Johns, Sr. Reliability Engineer, notes: "We currently have a model RD-800C IP tester from LIB, and it has been very useful in helping us develop new outdoor products (mostly security cameras and landscape speakers). We are very happy with it!"

LIB's IP6K9K test chambers provide a solution for multiple Ingress Protection levels. The IPX6K test delivers a high-pressure linear water jet (6.3 mm nozzle, 75 L/min ±5%, ~1 000 kPa) from a single direction at a distance of 2.5–3 m, simulating harsh cleaning or rain conditions. The IPX9K test exposes specimens to fan-shaped, high-pressure, high-temperature water sprays (14–16 L/min, 8 000–10 000 kPa, 80 °C ±5 °C) at fixed angles (0°, 30°, 60°, 90°), ensuring durability under extreme wash-down procedures. These tests allow for precise, repeatable validation of products under increasingly severe conditions.

IP9K TEST 

【Streamline Your Waterproof Testing: Full-Range IPX1–IPX9K Capabilities】

1. IPX1 & IPX2 – Vertical Drip Tests

IPX1: Simulates vertical dripping of 1 mm/min water for 10 minutes, ensuring basic rain resistance.

IPX2: Adds a 15° tilt test under the same drip rate to mimic condensation or tilted mounting scenarios.

2. IPX3 & IPX4 – Oscillating Tube Spray

IPX3: Tests against water spray at angles up to 60°, verifying protection against light rain and spray jets.

IPX4: Confirms IPX4 water resistance to water splashes from all directions at 10 L/min for 5 minutes, ideal for splash-prone equipment.

3. IPX5 & IPX6 – High-Pressure Jetting

IPX5: Uses a 6.3 mm nozzle at 12.5 L/min to verify performance under moderate jet washing.

IPX6(IP56 waterproof): Intensifies to a 12.5 mm nozzle at 100 L/min, replicating heavy-duty wash-down in automotive or industrial cleaning.

4. IPX6K – High-Pressure, High-Temperature Spray

LIB's IPX6K Water Spray Test Chamber delivers a high-pressure linear water jet (6.3 mm nozzle, 75 L/min ±5%, ~1 000 kPa) from a single direction at 2.5–3 m, accurately simulating harsh cleaning or heavy rain conditions.

5. IPX7 & IPX8 – Immersion Testing

IPX7: Submersion at 1 m depth for 30 minutes guarantees operation after brief immersion events.

IPX8: Offers deep immersion testing up to 50 m equivalent pressure, simulating flood or underwater deployment.

6. IPX9K – Extreme-Condition Water Jet & Heat

Delivers +88 °C water at 8 000–10 000 kPa through four nozzles at multiple angles (0°, 30°, 60°, 90°), each spraying for 30 seconds to verify sealing under the harshest high-pressure, high-temperature sprays.
