IAPMO IGC 354-2020 covers pipe lining systems employing polyethylene terephthalate (PET) lining systems intended for use in water supply pipes ranging from DN 15 to 50 (1/2 to 2 NPS) and specifies requirements for materials, physical characteristics, performance testing, and markings.

Polyethylene terephthalate (PET) pipe lining systems covered by this standard are intended for application in various pipe materials including but not limited to lead, copper, galvanized iron, steel, and plastic.

The lining is achieved by forming a thin?walled liner close?fitting to the interior of the existing pipe.
