Description
This Interim Standard specifies design and manufacture requirements for a polyethylene maintenance shaft (MS) comprising a moulded chamber and riser in one-piece seamless construction, or a moulded chamber jointed to a riser (normally a pipe) manufactured from a compatible material.
Scope
Maintenance shafts are intended for installation in sewerage systems (up to DN 300) for transportation of sewage at atmospheric pressure and average service temperatures up to 25C.
They are intended for buried vertical installation at depths up to 6 m, without buckling collapse and without exceeding long-term diametral distortion and stress limits as specified.
