Document Number: NL EN 295 4 : 2017
Sector: Construction Materials and Building
TC: NL TC 59
ICS:
This European Standard specifies requirements for adaptors and connectors made from vitrified clay and/or other suitable materials 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 insertable 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.
