Overview - EN 295-4:2013 (vitrified clay pipe systems, adaptors & couplings)
EN 295-4:2013 is the CEN European standard that sets requirements for adaptors, connectors and flexible couplings used with vitrified clay pipe systems for drains and sewers. It covers products intended for buried gravity sewer and drain networks (including domestic wastewater, surface water and rainwater), under periodic surcharge conditions or continuous low head pressure. The scope includes insertable fittings, sealing rings for cut pipes, heat‑shrinkable sleeves and metal‑banded flexible couplings with rubber, polyurethane, stainless steel and other components.
Key topics and technical requirements
This part of the EN 295 series focuses on practical product and performance requirements, including:
- Materials and manufacture: requirements for vitrified clay, rubber and polyurethane sealing elements, stainless steel bands and other components.
- Geometric properties: internal diameter, length, angles, squareness and joint interchangeability.
- Joint performance: tightness, bond strength for bonded clay parts, and joint assembly criteria for clay-to-clay and clay-to-other-material connections.
- Component-specific rules: metal‑banded flexible couplings (types with/without shear bands), adaptors, bushes, insertable fittings, sealing rings and heat‑shrinkable sleeves (see normative Annexes A–C).
- Durability and resistance: chemical resistance, reaction to fire, aging and dangerous substances.
- Conformity & marking: designation, marking, initial type testing (ITT) and factory production control (FPC) procedures - with further conformity and test method detail referenced in EN 295-2 and EN 295-3.
- Regulatory linkage: Annex ZA describes relevance to the EU Construction Products Directive and CE marking requirements.
Applications and users
EN 295-4:2013 is used by:
- Manufacturers designing and certifying adaptors, connectors and couplings for vitrified clay systems.
