Splash Water Test As Per ISO 16750-4

What is the ISO 16750-4 Splash Water Test?

ISO 16750-4 is an international standard that outlines environmental conditions and testing requirements for electrical and electronic equipment in road vehicles. The Splash Water Test within this standard assesses a product’s resistance to water impact caused by splashing, simulating real-world exposure in different environments.

Why is the Splash Water Test Important?

🚗 Ensures durability – Protects automotive components from water-induced failures.
⚙️ Enhances reliability – Reduces the risk of short circuits, corrosion, and performance degradation.
🔧 Meets industry standards – Ensures compliance with global automotive testing regulations.
🌍 Improves product lifespan – Helps manufacturers design robust products that withstand environmental exposure.

Testing Procedure for Splash Water Test (ISO 16750-4)

The Splash Water Test follows a structured methodology to simulate water exposure under controlled conditions. The testing process includes:

1. Test Setup

• The component is mounted inside a specialized test chamber.
• Water is splashed onto the test sample using nozzles or spray systems at a defined pressure, temperature, and volume.
• The angle and intensity of the water impact are specified based on real-world conditions.

2. Test Conditions

• Water Temperature: The test can be conducted with cold water (0°C to 4°C) or warm water, depending on the component’s application.
• Splash Cycles: Multiple cycles are performed to simulate repeated exposure over time.
• Duration: The duration varies based on industry requirements but typically lasts several minutes per cycle.

3. Post-Test Evaluation

After the test, the component is visually inspected and analyzed for:
✅ Corrosion
✅ Water ingress
✅ Electrical malfunctions
✅ Material degradation

Components that pass the test demonstrate high durability and water resistance, ensuring they can perform reliably in harsh conditions.

Applications of Splash Water Testing

The Splash Water Test is widely used across various industries, including:

🚘 Automotive: Testing sensors, connectors, control modules, and battery enclosures.
🔋 Electronics: Evaluating waterproof coatings, PCBs, and electrical housings.
🏗️ Industrial Equipment: Ensuring outdoor machinery can withstand wet conditions.
🚲 E-mobility: Verifying the water resistance of electric bikes, scooters, and charging ports.
