Overview

EN 15037-2:2009+A1:2011 is the CEN European Standard that specifies requirements and basic performance criteria for concrete blocks used in beam-and-block floor and roof systems. It covers blocks manufactured from normal or lightweight aggregate concrete to be used together with precast beams conforming to EN 15037-1, with or without a cast‑in‑situ topping. The document includes Amendment 1 (2011) and is intended for factory production, testing, conformity assessment and CE marking of precast concrete blocks.

Key topics and requirements

• Scope and definitions: Classification of block types - non‑resisting (NR), semi‑resisting (SR) and resisting (RR) blocks; longitudinal, transverse and open block geometries; terminology such as “nib”.
• Material and production: Material requirements reference EN 13369 and EN 771‑3 and address normal and lightweight aggregate concrete production methods.
• Finished product properties:
  • Geometrical and surface characteristics (dimensions, surface finish)
  • Mechanical resistance (tests for concentrated loads, bending strength, longitudinal and transverse compression for SR/RR blocks)
  • Durability, thermal and acoustic properties, and reaction/resistance to fire
  • Gross dry density and drying shrinkage (lightweight concrete)
• Test methods & sampling: Detailed test procedures for dimensions, strength, density and shrinkage; sampling rules for type testing and lot inspection are given in Annex A.
• Conformity and factory production control: Type testing, inspection schemes (Annex B), factory production control, marking and technical documentation requirements.
• Regulatory alignment: Annex ZA explains application of CE marking and relationship to the EU Construction Products Directive and relevant Eurocodes (EN 1992 series).

Applications and users

EN 15037-2 is used to:

• Specify and certify precast concrete blocks for beam-and-block floor and roof systems.
• Ensure consistent performance (structural behavior, fire, thermal and acoustic) across manufactured blocks.
• Support CE marking and conformity assessment for the EU market.

Typical users:

• Precast concrete manufacturers and quality managers
• Structural and façade engineers specifying beam-and-block solutions
• Contractors and installers of precast floor/roof systems
• Testing laboratories and conformity assessment bodies
• Product certification and compliance officers

Related standards

• EN 15037-1 (Beams for beam-and-block systems)
• EN 15037-3, -4, -5 (other block materials: clay, polystyrene, lightweight)
• EN 13369 (Common rules for precast concrete products)
• EN 1992-1-1 (Eurocode 2: design of concrete structures)
• EN 771-3 and relevant EN test standards
