Abstract
A testing apparatus for onsite creation of cured sample liners necessary for confirming proper rehabilitation of pipelines includes a testing box having a base with a plurality of upstanding side walls defining an open upper end of the testing box. The testing box also includes an electrical power control assembly and an ultraviolet light assembly. A liner support manifold is shaped and dimensioned for supporting a sample liner and for attachment to the open upper end of the testing box for exposing the sample liner to pressure and ultraviolet light. In practice, and with the sample liner secured to the liner support manifold and the liner support manifold secured to the testing box, the sample liner is exposed to pressure and UV light in a highly controlled manner allowing for replication of actual in-line curing processing.
