Overview
EN 12050-4:2015 - published by CEN - is the European standard that specifies requirements for non‑return valves used in wastewater lifting plants for buildings and sites. It covers non‑return valves for both faecal‑free wastewater and wastewater containing faecal matter, describing general requirements, construction principles, testing methods and conformity assessment (AVCP) including information on materials, durability and performance verification.
Key topics and technical requirements
- Scope and definitions: Applies to non‑return valves as either integrated or separate components of lifting plants; includes backwash devices and maximum pump operating pressure concepts.
- Materials: Corrosion‑resistant materials or protective coatings required; materials must not release dangerous substances.
- Mechanical resistance: Connections must resist longitudinal forces and the plant’s maximum pump pressure; no visible leakage under pressure testing (see Clause 5.2.4).
- Effectiveness: Valves must automatically prevent backflow and open reliably during pumping; effectiveness verified by specified tests (Clauses 5.2.1–5.2.5).
- Solids passage: Ball‑passage (Ds) requirement to avoid retention of solids and fibrous material: Ds ≥ 0.8·di − 4 mm (di = internal pipe diameter).
- Cleanability: Valves must be cleanable (except DN < 80 where cleaning provision is not required).
- Internal leakage: Maximum leakage limits during a 10‑minute test are defined by valve size (e.g., DN < 32 → 0.5 L; 32 ≤ DN ≤ 100 → 1 L; DN > 100 → 3 L).
- Nominal pressure: Minimum nominal pressure class is PN 4.
- Reaction to fire: Reaction‑to‑fire classification requirements included (references to EN 13501‑1 and EN 13823).
- Durability, noise and dangerous substances: Clauses address watertightness lifetime, mechanical durability, noise testing (EN ISO 20361) and hazardous substance restrictions.
- Assessment and verification of constancy of performance (AVCP): Type testing, factory production control (FPC), Declaration of Performance (DoP) and CE marking provisions are covered (Annex ZA reflects CPR / EU No. 305/2011).
Applications
- Specifying and testing non‑return valves for sewage and drainage pumping installations in residential, commercial and industrial buildings.
