Overview

EN 512:1994 (adopted as SIST EN 512:1996) is a CEN standard for fibre-cement products - pressure pipes and joints. The standard defines requirements for fibre‑cement pipes and their joints intended for conveying potable and non‑potable water and sewage under pressure. EN 512 covers composition, classification, dimensional and mechanical properties, physical characteristics, and the required acceptance tests and type tests for pressure applications.

Key topics and requirements

EN 512 focuses on the technical characteristics that ensure safe, durable performance of fibre‑cement pressure systems:

• Composition and materials: requirements for fibre‑cement formulation and material quality to achieve the necessary strength and durability.
• Classification: product classes based on intended use, pressure rating and mechanical performance.
• Geometrical characteristics: dimensional tolerances, nominal diameters, wall thickness and joint geometry to ensure interchangeability and proper hydraulic performance.
• Mechanical characteristics: requirements addressing pressure resistance, bending and impact behaviour appropriate for buried or exposed installations.
• Physical characteristics: durability, water tightness, resistance to internal/external corrosion and ageing.
• Joints and sealing: specifications for joint types (gasketed, spigot/socket, etc.), tightness and mechanical integrity under pressure.
• Testing and conformity: defined acceptance tests for production batches and type tests for product qualification, including performance verification under simulated operating conditions.

Applications

EN 512 applies to various water and wastewater infrastructure contexts:

• Distribution mains for drinking water and non‑potable water
• Pressure sewage and wastewater conveyance
• Service connections and small diameter pressurized lines
• Rehabilitation and replacement of ageing pressure pipelines where fibre‑cement is specified

Who uses this standard

• Manufacturers of fibre‑cement pipes and fittings for design, production control and product certification
• Civil and water engineers specifying pipe systems for potable water and sewage networks
• Water utilities and municipalities procuring pressure pipe systems and ensuring compliance
• Testing laboratories and certification bodies performing acceptance and type testing
• Contractors and installers referencing joint geometry and installation requirements

Related standards

While EN 512 specifically addresses fibre‑cement pressure pipes and joints, complementary standards typically cover test methods, installation practices and materials for water and wastewater systems (refer to national and CEN lists for applicable test standards and installation codes).
