Bubble test
The Bubble test has two purposes; one is to locate the placement of a hole in a package. To
do this place the package (with septum and needle) under water.

Secondly you can test for example that a Tyvek package functions as intended, meaning that
it only leaks within a specific pressure range. This test also requires for the package to be
under water.

A Bubble test inflates the package to a specific pressure and maintains this pressure for a
specified time period. The Bubble test is compliant with ASTM F2096.
CAUTION! It is possible that the package will burst during a Bubble test. Please note
that the pressure may not drop to a low level immediately after the test.
NOTE! When testing filled packages, precautions may be necessary to ensure that
the product does not contaminate the operator or the system. Depending on the
package contents, the use of safety glasses may be advisable. A protective hood
placed over the package may offer additional protection.
A Bubble test is divided into 2 phases:
 The package is inflated to the test pressure.
 The test pressure is maintained for a fixed period of time.
When test ends you must select whether the test was passed or not.
CAUTION! If the package did not burst, it is still under pressure! Remove the
package carefully; a sudden pressure drop will occur when it is removed.
