Industrial leak testing
We are passionate process engineers and are constantly developing our process expertise. In doing so we rely on more than just theory. In the face of demanding testing scenarios, we evaluate the usability of a procedure by carrying out a range of tests in our technical centre.
Our many years of experience in industrial applications mean we are able to assess which testing procedure will deliver process-reliable test results even in demanding production conditions. If needed, we can advise you of advantages and disadvantages with respect to your individual use case.
Our portfolio of leak testing procedures includes the widely recognised test procedures of DIN EN 1779 as well as individual solutions. Our activities are focused on implementing the following test methods:
Test gas methods
- Integral vacuum testing
- Accumulation testing
- Sniffing testing
Test gas methods are based on the proof of helium or other test gases such as forming gas, nitrogen or air. Other gases are available on request.
Pressure change methods
- Pressure increase testing
- Pressure drop testing
- Differential pressure testing
With pressure change methods, it is mostly air or N2 that is used as the test medium.
Other methods
- Combination testing (various test procedures)
- Bubble testing (water bath)
- Flow testing
- Optical testing
Are you uncertain of which is the right procedure for your use case? Then talk to us. With more than 35 years of experience in practical implementation and our wide range of reference projects, we are the experts when it comes to industrial leak testing.
Do your specifications go beyond “normal” leak testing?
That’s not a problem for us. As leak rate is often not the only criterion that determines the quality of a test object, we also implement test procedures that review other product-specific properties besides leak testing.
Pressure testing
To prove leaktightness, a test pressure is established in the test object that exceeds the maximum operating pressure. Air or water is used as the testing medium, depending on the use case.
Function test
In some cases electrical and/or mechanical tests are needed to ensure that there is no malfunction of the test object. Testing for safety-relevant components, for example, can be efficiently and economically integrated into the production process.
The possibilities of combining various testing methods can be implemented in a variety of ways. The options for inclusion in the production process are also flexible.
