CIPP Liner Testing QA Services

Paragon Systems Testing is a leading Cured-In-Place-Pipe CIPP liner testing centre and was the pioneer North American testing laboratory to introduce the ASTM D2290 apparent tensile test to the pressure pipe rehabilitation lining industry.

With over 20 years of experience as a CIPP testing lab, We are fully conversant with and capable of performing all North American (ASTM D5813, ASTM F1743, ASTM F2019), International Standards (ISO 11296-4, ISO 178 CIPP), European (EN) and Quebec (BNQ) CIPP liner testing procedures.

ASTM D790 flexural testing

Short-term flexural modulus is one of the primary cured-in-place-pipe CIPP liner testing properties used in the design of a CIPP liner.

Tangent modulus and flexural strength are used to characterize the ASTM F1216 flexural properties of a CIPP liner which is loaded in bending.

Cured-in-place-pipe installations are field installations and for this reason, the representative test samples from each installation will be quite varied.

Sewer, watermain, unreinforced, reinforced, gravity or pressurized – each type of CIPP liner requires a thorough understanding of the specimen preparation and testing techniques that need to be used if accurate flexural data is to be generated.

Paragon Systems Testing is the only North American independent  cipp testing lab to have established the connection between flexural test specimen preparation and its effect on measured flexural properties in cured in place pipe liner testing.

Our peer-reviewed research in this field has been published at many trenchless industry conferences.

ASTM d5813

cipp hoop tensile testing

ASTM D2290 apparent tensile strength test for CIPP liners

Pressure pipe CIPP liners, generate most of their strength in the 90 degree orientation.

Hoop Tensile testing a CIPP pressure pipe liner in this direction to confirm the CIPP liners properties is complicated by the fact that a liner field sample is cylindrical so an ASTM D638 conforming tensile test coupon cannot be prepared.

The ASTM D2290 test method provides a technique for more readily measuring the 90 degree orientation tensile properties on CIPP pressure pipe liners where the hoop direction properties prevail.

ASTM f1743

cipp wall thickness testing

Pipe Thickness

Wall thickness is a critical liner property which is used to determine conformance of a CIPP liner to a liner design.

Sewer, watermain, unreinforced, reinforced, gravity or pressurized – each type of CIPP liner requires a thorough understanding of the design of the liner in order to accurately measure a CIPP liner wall thickness.

ASTM f2019

The main benefit of CIPP liners is the 50 to 75 year life extension that the material provides when it is properly installed by an experienced installer.

The life extension for sewer liners is predicated on long term creep testing of the specific CIPP liner resin chemistry used.

CIPP liner owners or contract administrators can verify that the resin used in a CIPP liner installation is the same resin used to obtain long term creep data by sampling resin from the installation.

Infrared spectrographic analysis of liner resin comparison

Spectral analysis (FTIR) is a valuable tool in your CIPP quality control tool kit. A CIPP liner resin sample taken during installation of the liner can be compared to the same “fingerprint” of the resin used for the original creep testing to confirm that the correct, long term creep qualified resin is actually being installed.
