DIN EN 295-4:2013-05 EN 295-4:2013 (E) 5 1 Scope This European Standard specifies requirements for adaptors and connectors made from vitrified clay and/or other suitable materials
35、for use with vitrified clay pipes and fittings 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. Adaptors and connectors include ins
36、ertable fittings, sealing rings for cut pipes and heat-shrinkable sleeves. This standard also applies for metal banded flexible couplings and adaptors and specifies requirements for rubber, polyurethane, stainless steel and other components used for them. NOTE 1 The specifiers/purchasers can select
37、adaptors, connectors and flexible couplings according to their requirements. 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. 2 Normative references The following d
