Burst test
A Burst test checks the strength of a package sealing by increasing the pressure in the package until it
bursts. The Burst test is compliant with ASTM F2054.
CAUTION! As the bursting of the test package may lead to considerable noise, we
recommend wearing hearing protection.
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 Burst test is divided into 2 phases:
 The package is inflated to the set pre-fill pressure.
 The pressure in the package is increased at the pre-set rate until the package bursts or until the
maximum specified pressure is reached.
The results from the Burst test are:
• Measured burst pressure (if the package bursts)
• Package burst time (
)
• PASS - if the package bursts within the pre-set burst limits
• FAIL - if the package bursts outside the pre-set burst limits.
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.
