Product Overview

The rain test chamber IPX9K is a high-pressure, high-temperature water spray testing system designed to evaluate the protection level of enclosures against powerful steam-jet cleaning procedures. It is widely used for automotive components (passenger cars, buses, tractors, motorcycles), electronic products, and any device that may be exposed to high-pressure and high-temperature water jets during service. The rain test chamber IPX9K simulates the rigorous conditions defined by ISO 20653-2013 and VW80000, making it an indispensable tool for quality assurance, R&D, and compliance testing in the automotive and electronics industries.

Product Features

The rain test chamber IPX9K combines robust construction with advanced engineering to deliver accurate and repeatable tests:

IPX9K dedicated testing – Specifically designed to meet the IPX9/9K waterproof rating requirements.
Sturdy construction – Outer shell made of high-quality steel with baked paint finish; inner chamber and turntable constructed entirely from SUS304 stainless steel for long-term corrosion resistance.
Enclosed chamber design – Built-in water tank with recirculating water system; level sensors for automatic refill and low-water alarm to prevent pump dry-running.
Four high-pressure nozzles – Arranged vertically at 0°, 30°, 60°, and 90° inside the right wall, strictly according to standard specifications.
Adjustable nozzle distance – 100–200 mm from the test specimen, manually adjustable.
High-performance pump – Imported original pump resistant to high temperature and high pressure, ensuring stable long-term operation.
Precision turntable – 400 mm diameter, load capacity 50 kg, rotation speed 4–10 rpm (precisely adjustable via touch screen). Manual height adjustment.
Touch screen control system – 7-inch interface with dedicated controller; electrical components from LS, Omron, etc. Test time settable (0–999 min). Standard test cycle: 120 seconds total (30 seconds per spray position).
Observation and access – Tempered glass window on the door, LED interior lighting; 50 mm cable port (with rubber plug) for external sample power supply.
Complete safety protections – Leakage protection, water shortage protection, short-circuit protection.

Test Standards

The rain test chamber IPX9K strictly complies with:

ISO 20653-2013 – Road vehicles – Degrees of protection (IP code) – Protection against high-pressure/high-temperature water jets.

VW80000 – German automotive standard for IPX9K testing.

Key test conditions under these standards:

Water flow rate: 14–16 L/min

Water pressure: 8000–10000 kPa (approx. 80–100 bar)

Water temperature: 80±5°C (room temperature also available by agreement)

Nozzle angles: 0°, 30°, 60°, 90° (vertical)

Spray duration: 30 seconds per angle, 120 seconds total

Turntable rotation speed: 5±1 r/min (or as specified)

All parameters can be directly set on the touch screen, ensuring full compliance with IPX9K requirements.

FAQ

Q1: What is the difference between IPX9 and IPX9K?

A: IPX9 and IPX9K are essentially the same test method – high-pressure, high-temperature water jets from four angles. The term IPX9K is often used in automotive standards such as VW80000. This rain test chamber IPX9K meets both ISO 20653 and VW80000.

Q2: Can I test samples that require external power during the test?

A: Yes. The chamber has a 50 mm cable port on the side, fitted with a rubber plug. You can feed your sample's power cord through this port (external power source to be provided by the customer).

Q3: What is the water temperature range?

A: Standard configuration supports both ambient (room temperature) and 80±5°C. The heating system can achieve the high temperature required by IPX9K. Deviations can be negotiated during ordering.

Q4: How is the water supply managed?

A: The chamber has a built-in water tank with recirculating capability. An automatic float valve refills the tank from a laboratory faucet (minimum 0.2 MPa water pressure, 1/2 inch tap). Low-water level sensors protect the pump.

Q5: What maintenance is required?

A: Regularly inspect the nozzles for clogging. The water filter (if present) should be checked periodically. The stainless steel interior requires only routine cleaning. The imported pump is designed for long-term, maintenance-free operation.
