IKT – Institute for Underground Infrastructure

Test Centre for CIPP liners

The IKT Test Centre is a supervisory body for CIPP liners and short-liners and is recognised by the German Institute for Construction Technology (DIBt). It is accredited to European Standards (DIN EN ISO/IEC 17025) for selected mechanical and technical tests on polymeric components of pipe and CIPP liner systems and samples of GRP laminate, e.g.

• modulus of elasticity (short-term flexural modulus)
• flexural strength (flexural stress at rupture)
• wall thickness (mean combined thickness)
• water tightness
• glass transition temperatures (DSC analysis)
• expanded-scope tests, e.g. spectral analysis, 24 hr creep, density
