Overview

EN 1504-7:2006 is the CEN (European) standard that specifies requirements for products and systems used for reinforcement corrosion protection in repaired concrete structures. It covers identification, performance (including durability), quality control and evaluation of conformity for active coatings (electrochemically active pigments, inhibitors or localized cathodic protection) and barrier coatings (which isolate embedded, uncoated steel from pore water). This Part explicitly excludes products for pre-stressing steels and stainless steels.

Key topics and technical requirements

• Scope and definitions: Aligns with EN 1504 series definitions for repair and protection of concrete structures; focuses on coatings applied to existing, uncoated reinforcement.
• Identification tests (manufacturer responsibility): visual appearance, density, infrared spectrum, epoxy/amine functions (where applicable), volatile/non‑volatile content, thermogravimetric analysis, viscosity, pot‑life, consistency, thixotropy, and hardness - with specified tolerances and record retention.
• Performance requirements:
  • Corrosion protection: verified by test method EN 15183 - coated steel zones must be free of corrosion; rust creep limits apply.
  • Glass transition temperature (EN 12614): product Tg at least 10 K above maximum service temperature.
  • Shear adhesion (EN 15184 pull‑out test): bond stress with coated bars ≥ 80% of the uncoated reference at 0.1 mm displacement.
• Quality control & conformity:
  • Factory Production Control (FPC) required; FPC procedures described in EN 1504-8 and include minimum testing frequencies (informative Annex A).
  • Initial type testing, sampling, assessment and surveillance are defined in EN 1504-8.
• Environmental / health: products must not release substances hazardous to health or the environment (see Annex B / Annex ZA relating to Construction Products Directive and CE marking).

Applications - who uses EN 1504-7:2006

• Concrete repair manufacturers developing or certifying corrosion protection coatings (active and barrier types).
• Specifiers, structural and corrosion engineers selecting products for rehabilitation of reinforced concrete elements (beams, columns, bridges, tunnels).
• Contractors and QA/QC teams implementing factory production control, testing and CE marking procedures.
• Test laboratories performing EN 15183, EN 12614 and EN 15184 test methods.
