This European Standard specifies requirements for vitrified clay pipes, fittings and flexible joints 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 standard also specifies requirements for rubber, polyurethane and polypropylene materials and other components used for jointing clay pipes and fittings. This standard specifies different strength classes, systems of joint dimensions, lengths and fittings. NOTE 1 The specifiers/purchasers can select them according to their requirements. This standard does not apply to special fittings, adaptors and compatible accessories, perforated pipes and fittings, manholes and inspection chambers and pipes and joints for pipe jacking, which are specified in other parts of the standard series EN 295. 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.
