ASTM F2994-18

1.1 This practice describes the procedures for the impregnation of 2 to 48 in (50 to 1200 mm) diameter cured-in-place pipe utilizing mobile, automated systems. Temporary impregnation facilities set up at the jobsite (“over-the-hole” wet outs) are not covered under this standard. Once resin saturation is complete, the wet out liner is then used to rehabilitate existing gravity flow or pressure pipelines, process piping, electrical conduits or ventilation systems.
