A representative sample of an installed liner needs to be taken on-site before testing in the IKT laboratory. Samples of CIPP liners which are cured by UV light (“UV-curing liners”) should be packed in light-tight film or foil before being taken out of the manhole.

 

 

 

 

 

Site sample of CIPP liner: 200 mm x 350 mm

Site sample of CIPP liner: 200 mm x 350 mm

CIPP liners larger than DN 200

The necessary dimensions of such liner samples are:

  • Total wall thickness up to 10 mm:
    Sample must measure not less than 200 mm x 350 mm
  • Total wall thickness greater than 10 mm:
    • Circumferential direction: 20 x total wall thickness
    • Longitudinal direction: 350 mm

 

 

 

CIPP liners up to DN 200 and sewer lateral liners

A complete circular ring should be taken for the vertical-compression test if on-site circumstances permit this.

Necessary sample length:
Pipe diameter + 50 mm

Examples:

  • Pipe DN 150: Sample length = 200 mm
  • Pipe DN 200: Sample length = 250 mm

 

 

 

DSC analysis

Sample for DSC analysis: 20 mm diameter necessary

Sample for DSC analysis: 20 mm diameter necessary

A round liner sample of approx. 20 mm diameter is sufficient as a sample for DSC analysis performed on epoxy resins.

CIPP liner test standards

The minimum scope of testing for CIPP liners consists of the three-point bending test for determination of modulus of elasticity and bending stress, and the water tightness test.

Further tests are available, as defined in the ZTV Materials Testing (CIPP liner test standards), which make it possible to determine the quality of CIPP liners even more precisely.
