Bubble Emission Leak Test Chamber Bubble Leak Testing Method using an acrylic vacuum chamber
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 :
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 can be detected with immersion leak test. The bubble leak test is accurate to of 10-3 atm-cc/sec. The accuracy of leak test is better than air decay leak test, pressure decay leak test, flow rate leak test dye penetration test. but it should not be compared with traces gas leak test, high vacuum leak test and gas sniffing methods according to bubble leak test standard.
To recap, the advantages of bubble emission leak testing are:The bubble leak test can be utilized on variously shaped and sized specimen - whether that may be a pouch, tray, box, vial, bottle, etc…
