Defines requirements for vitrified clay pipes and joints for pipe jacking for buried drain and sewer systems for the conveyance of wastewater (including domestic wastewater, surface water and rainwater) under gravity and periodic hydraulic surcharge or under continuous low head of pressure.

This European Standard specifies requirements for vitrified clay pipes and joints for pipe jacking for buried drain and sewer systems for the conveyance of wastewater (including domestic wastewater, surface water and rainwater) under gravity and periodic hydraulic surcharge or under continuous low head of pressure. Pipe jacking techniques include micro-tunnelling, pipe-eating, pipe bursting and where appropriate lining with discrete pipes.

This standard also specifies requirements for rubber, polyurethane, polypropylene, stainless steel and other materials used for joints for pipe jacking.

NOTE Corresponding provisions for the evaluation of conformity (ITT and FPC) and sampling and those for the test methods are further specified in EN 295-2 and EN 295-3 , respectively.
