Unlike factory-finished pipes, CIPP liners attain their ultimate geometrical and mechanical properties only after in-place curing at the installation site. The quality of the work performed on site is thus critical for the quality of the end product.
To address this issue, the tests explained in more detail below are required in ZTV Materials Testing (CIPP liner test standards) as well as DWA Code of Practice 144-3 and DWA Standard 143-3 for quality assurance purposes.IKT is an accredited test and supervisory body recognised by the German Institute for Construction Technology (DIBt) for the performance of tests on CIPP liners and plastics.
IKT tests samples of CIPP liners taken on-site impartially and independently on behalf of project clients. The test report documents in detail whether the required quality criteria have been achieved.
The institute publishes its IKT LinerReport each year detailing the performance of both liner systems and contractors.
Flexural strength (flexural stress at rupture)
Wall thickness (mean combined thickness)
Glass transition temperatures (DSC analysis)
Further tests are available, as defined in the ZTV Materials Testing for CIPP liners specification, which make it possible to determine the quality of CIPP liners even more precisely.
The importance and benefits of these expanded-scope tests for the project client are explained in detail here:
