What is an airtightness testing machine? What is its function?
An airtightness testing machine is a device that uses air pressure to test whether a product has good sealing and waterproof capabilities. It is commonly used for wires, connectors, and electronic components with protection ratings such as IP67 and IP68. Because direct water testing presents challenges such as difficulty in drying, contamination risks, and oxidation problems, airtightness testing machines simulate water pressure or water flow impact through precisely controlled air pressure. This allows for rapid confirmation of air or water leakage risks in a completely water-free environment. The principle involves placing the product in a sealed chamber and applying a specific air pressure; by monitoring pressure changes, the reliability of the sealing structure is determined.
The waterproof testing standards followed by airtightness testing typically include IEC 60529 (IP rating standard) commonly used in industry, and ISO 20653 (road vehicle waterproofing and dustproofing specification) used in the automotive industry. Through the test conditions and pressure simulation methods defined by these international standards, the sealing reliability of products in real-world usage environments can be ensured.
