EN 588-1:1996

Overview

EN 588-1:1996 is a CEN standard that sets requirements for fibre-cement pipes, joints and fittings for gravity systems used in sewerage and drainage. It applies to products intended to operate at atmospheric pressure (free‑flowing gravity systems) and covers the most commonly used fittings such as angled branches, tees and bends. The standard defines expected composition, performance classification, dimensions and required test regimes to confirm suitability for external sewage and drainage use.

Key topics and technical requirements

• Scope and applicability: Pipes, joints and fittings for gravity sewer and drainage systems operating at atmospheric pressure; limited to widely used fittings (e.g., branches, tees, bends).
• Material composition: General composition requirements for fibre‑reinforced cement products to ensure consistent manufacturing and long‑term durability.
• Classification: Performance classes or designations that relate to mechanical and structural properties, enabling product selection for different load or service conditions.
• Geometrical characteristics: Specified dimensions, tolerances and interface features to ensure compatibility between pipes, joints and fittings.
• Mechanical and physical characteristics: Minimum strength, stiffness and other physical property requirements to resist handling, installation loads and in‑service stresses.
• Acceptance and type tests: Defined test methods and criteria (acceptance tests for production batches and type tests for product families) to verify compliance with the standard.

Practical applications

• Designing and specifying gravity sewer mains, stormwater drains and lateral connections for municipal, commercial and residential infrastructure.
• Selecting compatible joints and fittings (tees, bends, angled branches) for fibre‑cement piping systems to ensure leak‑free, durable assemblies.
• Establishing quality control and procurement criteria for manufacturers, contractors and public works authorities.
• Performing conformity testing and product validation in testing laboratories and inspection bodies.

Who uses this standard

• Civil and drainage engineers specifying pipework for external sewage systems.
• Pipe and fitting manufacturers developing fibre‑cement products.
• Construction contractors and installers responsible for procurement and installation.
• Test laboratories and certification bodies conducting type and acceptance tests.
• Public authorities and specifiers ensuring compliance with national drainage regulations.

Related guidance

EN 588-1:1996 should be used alongside other CEN/EN standards and local regulations governing pipe testing, jointing methods and sewer design to ensure a complete, compliant solution for gravity drainage systems.
