This Technical Report gives guidance for the assessment of conformity of vitrified clay pipe systems for drains and sewers including pipes, fittings, manholes, perforated pipes, jacking pipes and associated products by the establishment of voluntary third-party certification procedures.
It is recommended that the quality management system conforms to or is no less stringent than the relevant requirements to EN ISO 9001.

This European Standard applies for components for vitrified clay manholes and inspection chambers 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.
It specifies different strength classes and heights of sections. It also specifies the requirements for components used for joints, systems of joint dimensions and the materials rubber, polyurethane and polypropylene used for joints.
NOTE 1   The specifiers/purchasers can select the components for vitrified clay manholes and inspection chambers according to their requirements.
This standard does not apply to manhole tops and cover slabs.
NOTE 2   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.
