Waterproof Tester – How It Ensures Electronic Products Meet IP67/68 Standards

In today’s world, smartphones are almost indispensable, and wearable devices as well as smart home appliances are becoming increasingly popular. The waterproof performance of these devices has become a critical benchmark for both product quality and market competitiveness. Consumers now pay close attention to whether electronic products are certified with IP67 or IP68 waterproof ratings. This article explores how a waterproof tester plays a vital role in ensuring these IP protection levels.

1. What Do IP67 and IP68 Ratings Mean in Waterproof Testing?

According to the international IEC 60529 standard, the IP (Ingress Protection) rating consists of two digits:

• The first digit represents dust protection (maximum value is 6, meaning complete dustproof performance).
• The second digit represents waterproof protection, ranging from 0 to 8.
• IP67: Products can be immersed in water up to 1 meter deep for 30 minutes without damage.
• IP68: Provides stronger waterproof performance, enabling devices to operate at greater depths for longer durations, with specific standards agreed upon by manufacturers and certification bodies.

To reliably achieve IP67/68 compliance, electronic products must undergo strict and dependable waterproof testing with advanced airtightness testers.

2. How Does a Waterproof Tester Work? – Key Testing Methods

Understanding the working principle of waterproof testers is essential to grasp their role in IP67/68 verification. Currently, the most effective methods include: direct pressure testing, differential pressure testing, and flow testing.

Unlike immersion tests, these approaches provide non-destructive testing, preventing product scrapping after testing and ensuring consistent IP-level compliance.

3. Waterproof Tester Operation Guide – Is It Complicated?

Thanks to continuous upgrades, waterproof testers are now highly user-friendly. The general operation process is as follows:

• Product Clamping: Place the electronic device into the fixture, ensuring proper sealing.
• Pressure Application: Apply a set pressure to the product or test chamber, simulating real-world water pressure.
• Data Collection: High-precision sensors monitor pressure changes and record data in real time.
• Result Evaluation: • No leakage → product passes IP67/68 requirements. • Leakage detected → system automatically marks failure and triggers alarm.

These streamlined steps enable manufacturers to perform fast, batch-level waterproof testing, ensuring defective products do not reach the market.
