Material Tests

Measurement of Composite Thickness

Any excess neat resin on the back of the test piece (corresponding to the outside of the liner pipe), especially if forming a layer of irregular thickness, may be partially or wholly ground off prior to testing, in order to comply with thickness tolerances or to reduce associated error in the measurement of flexural modulus, provided that no part of the intended composite is thereby removed.

Resin-rich layers including any abrasion layer which are a deliberate part of the CIPP wall structure shall not be deducted from composite thickness or ground off prior to testing.
