Leak testing is an essential part of quality control in various manufacturing ; industries, ensuring that products meet stringent safety and reliability standards. From automotive parts to medical devices, the importance of leak testing cannot be overstated.

Leak testing is paramount in manufacturing, where the quality and safety of products must be assured. In industries such as automotive, electronics, and medical devices, even a minor leak can lead to significant failures, affecting the product’s functionality and safety.In the automotive industry, it is crucial to thoroughly test the leak-tightness of components like radiators, fuel systems, and air conditioning systems. This helps prevent dangerous situations such as coolant or fuel leaks, which could lead to accidents or environmental harm.

Leak testing is utilized across a wide range of industries:

• Automotive Industry: Ensures the tightness of fuel systems, radiators, and air conditioning units.

• Medical Devices: Ensures that devices such as syringes, vials, and surgical instruments are safe and reliable.

• Electronics: Ensures the water resistance and durability of devices like smartphones and watches.

Each application demands a specific approach to leak testing, considering factors such as the medium (gas or liquid), the pressure conditions, and the environmental factors the product will face.

Leak testing presents a number of challenges, not least the accuracy required to detect leaks. The sensitivity of the test equipment, the choice of appropriate methods, and the interpretation of results are all crucial.

For example, while a simple water immersion test might be enough to spot large leaks, detecting micro-leaks needs more advanced techniques, like helium testing or ATEQ’s differential pressure test.

The concept of leak rate is central to leak testing. Leakage rate is a measure of the volume of gas or liquid escaping from a product over time, under specific conditions. It is quantified in units such as Pa-m³/s, mbar*l/s, or cm³/min, depending on the medium and testing method used.

The acceptable leak rate varies by industry and application, with more critical systems requiring stricter limits.

Several methods are used in leak testing, each suited to different applications:

• Differential Air Pressure Method: Commonly used in automotive and industrial applications.

• Helium Testing: Highly sensitive, used for detecting micro-leaks in critical components.

• Water Immersion Testing (well known as bubble test): A traditional method for visual detection of significant leaks.

The choice of method depends on the required sensitivity, the type of leak being tested, and the product’s operational environment.

At ATEQ, we have a long tradition of offering a wide range of non destructive testing air pressure testers with ever-increasing performance. We now offer helium testers with the new VIC products.

Selecting the appropriate leak testing method involves considering various factors, such as the medium involved, the pressure conditions during operation, and the acceptable leak rate.

For instance, helium testing is preferred for its accuracy in detecting small leaks in critical components.

Leak testing also plays a role in cost management and environmental protection. By preventing leaks, manufacturers can reduce waste, avoid costly recalls, and minimize their environmental footprint.

For example, tight fuel systems in vehicles prevent the escape of harmful emissions, contributing to environmental protection and regulatory compliance.
