DIN EN 295-6:2013-05 EN 295-6:2013 (E) 5 1 Scope 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)
31、 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 polypro
32、pylene 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
33、and FPC) and sampling and those for the test methods are further specified in EN 295-2 and EN 295-3, respectively. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
