This European Standard provides requirements and test methods for flexible, pre-insulated, directly buried
district heating pipe assemblies with metallic service pipes and bonding between the layers of the pipes and
thermal insulation materials of polyurethane or polyisocyanurate foam, the casing pipes being made of
polyethylene.
This European Standard is valid for maximum operating temperatures up to 140 °C and pressures up to
25 bar for a design lifetime of at least 30 years.
