Overview

EN 15655-1:2018 is a CEN European Standard that specifies requirements and test methods for factory-applied internal polyurethane (PU) linings on buried ductile iron pipes, fittings and accessories. It covers heavy‑duty corrosion protection for items conforming to EN 545 (water), EN 598 (sewerage) and EN 969 (gas) for permanent operating temperatures up to 45 °C. The standard defines production controls, routine and performance tests, and quality assurance measures for polyurethane lining systems.

Key Topics

• Scope and applicability
  • Internal polyurethane lining of ductile iron pipes and fittings for buried service (water, wastewater, gas networks).
  • Designed for permanent operating temperatures up to 45 °C.
• Surface preparation
  • Blast cleaning and surface roughness requirements prior to lining application; substrate temperature control relative to dew point.
• Finished lining requirements
  • Appearance and continuity, minimum lining thickness (specified in tables within the standard), non‑porosity (holiday testing), pipe end protection, repairs and marking.
• Mechanical and physical properties
  • Adhesion (pull‑off), indirect impact strength, resistance to ovalization, elongation at break, glass transition temperature, specific electrical resistance of the lining.
• Chemical and abrasion resistance
  • Chemical resistance performance tests; abrasion resistance required where applicable (notably wastewater applications).
• Testing framework
  • Routine production tests and more extensive performance tests (e.g., Differential Scanning Calorimetry (DSC), adhesion per EN ISO 4624, and other referenced ISO/CEN test methods).
• Quality assurance and documentation
  • Informative annexes cover QA, lining process and materials, DN grouping for tests, and packaging.

Applications and Users

• Who uses it
  • Pipe and fitting manufacturers, coating applicators, utilities (water, wastewater, gas), civil/mechanical engineers, procurement/specification professionals, and testing laboratories.
• Practical uses
  • Specifying and verifying internal polyurethane corrosion protection for new ductile iron pipelines and fittings used in potable water, sewerage and gas distribution networks.
  • Setting acceptance criteria for factory linings, production controls, and supplier quality assessment.

Related Standards

• EN 545, EN 598, EN 969 (ductile iron pipes/fittings for water, sewerage, gas)
• EN 14901 (epoxy coating of fittings)
• EN ISO 4624, EN ISO 62, EN ISO 527-3, EN ISO 868, EN ISO 8501-1, EN ISO 8503-1 (test methods referenced)
