Stainless Steel Inline Pouch Leak Detection System

Bubble Leak Testing Method using an acrylic vacuum chamber A bubble emission leak test chamber is a specialized apparatus designed to detect and locate leaks or defects in a wide range of products and materials. This comprehensive guide will provide insight into the principles, applications, benefits, and considerations associated with bubble emission leak test chambers.Introduction to Bubble Emission Leak Test Chambers:The integrity and safety of various products, from industrial components to consumer goods, depend on their ability to contain fluids or gases without leaks. A bubble emission leak test chamber serves as a critical quality control tool, allowing manufacturers to identify and rectify defects before products reach the market.Principles of Bubble Emission Leak Testing:The underlying principle of bubble emission leak testing is based on the behavior of gases escaping from a leak site when subjected to a submerged liquid. When a product with an internal leak is placed underwater, the gas escaping from the leak forms visible bubbles, providing a clear visual indication of the defect's location. Bubble Emission Testing or Bubble Leak Test method is a procedure to detect leaks visually by immersing the test specimen in water. Burhani Engineering Technology is manufacturer of acrylic vacuum box leak testing device. We will discuss advantage and disadvantage of vacuum bubble leak emission test procedure and internal pressurization vacuum chamber. There are Two testing Methods which are commonly used in bubble leak testing methodologies adopted for bubble emission detection. These are : A. ASTM D 3078: Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission B. ASTM F 2096: Standard Test Method for Detecting Gross Leaks in Packaging by Internal Pressurization (Bubble Test)     Product Catogories Internal Pressurization Bubble Testing System for ASTM F2096 ASTM F2096 Bubble Leak Test Machine What is a Bubble Leak Test Equipment ? Bubble testing is the least expensive and simplest method of assessing and detecting leaks. A differential pressure is created across the package with water chamber at lower pressure side and air on the high pressure side. Integrity Testing utilizing a Vacuum Chamber (ASTM D3078) Bubble Leak Testing using an acrylic vacuum chamber - It is also known as submersion leak test, bubble emission leak test, under water leak test and dunking test. This a a methodology to detect and locate leaks in the specimen through bubble emission. Vacuum ASTM D3078 and Pressurized ASTMF2096 are the two ways to perform bubble emission leak test . The Burhani Engineering Technology bubble leak test equipment is an acrylic vacuum chamber which is transparent and enables full view of the interior during testing. The acrylic chamber is used with vacuum pump which can pull 30 inch Hg. Burhani Engineering Technology can also supply vacuum Chamber with Venturi pump. This can be used with pressurized air setup or a compressor. This venturi pump converts pressurized air into vacuum. Integrity Testing utilizing an Internal Pressurization System (ASTM F2096) The pressurized ASTMF2096 method is when the specimen is pressurized above the atmospheric pressure, based on the altitude of the test, the gauge pressure can be set to the required pressure value. The specimen is pressurized through feed tubes connected to a compressor during bubble leak test. There is a better leak detection due to pressurized air present inside the test specimen. But this is a time consuming and complex process. Also all test specimen get damaged due internal pressure and burst. While the vacuum test Method ASTMS3078 is the simplest and quick process. When a leak is detected in the test specimen, the air will start to flow from high pressure to lower pressure region . This is the reason the submerged part will emit air bubbles, which can be detected visually. A hole size of 0.001 inch or 0.025 mm.
