4. Tests
Test types
Standard tests
The following standard tests can be performed:
• Burst Test/Seal Strength – see page 36
• Leak Test/Pressure Loss – see page 39
Creep tests
When the Creep Test option has been purchased, a Creep test or a Creep2Fail test can be performed
according to ASTM F1140. The creep test evaluates the strength of the seal on a package.
• Creep test – see page 42
• Creep2Fail test – see page 45
Combined testing
When the Multi-Test option has been purchased (requires the Creep Test option ), the Creep , Leak and
Burst tests can be combined in various ways and performed as a single test. The results of each
individual test will be reported at the end of the test sequence. Combined testing can simplify operator
setup and reduce the number test samples required.
The following combined tests to be performed:
• Combined Creep/Burst
• Combined Creep/Leak
• Combined Creep/Leak/Burst
Bubble test
When the Bubble Test option has been purchased (requires the Creep Test option ), a bubble test can be
performed according to ASTM 2096.
The test can be used to see where a leak is placed or to check the barrier of for example a Tyvek package
- see page 48 for details.
Test values
Testing of a new type of package always starts with finding the approximate burst pressure of the
package as this pressure is the basis for all other tests.
The burst reference pressure is found by trial and error and when an approximate reference value has
been found, the test is repeated 10-15 times to check whether stable test results are achieved using this
value.
