EN 15037-4:2010/FprA1

Precast concrete products - Beam-and-block floor systems - Part 4: Expanded polystyrene blocks

This European Standard deals with the requirements and the basic performance criteria for blocks made in expanded polystyrene (EPS), used in conjunction with precast concrete beams in compliance with EN 15037-1, with or without cast-in-situ concrete for the construction of beam-and-block floor systems. EPS block may be totally made in EPS or combined with different materials such as plaster or wood wool. If EPS is combined with other materials, these materials should not contribute to more than 50 % of the mechanical resistance of the block. If not, the block is covered by EN 15037-5, Precast concrete products - Beam-and-block floor systems - Part 5: Lightweight blocks for simple formwork. Examples of typology of floor systems are given in Annex B of EN 15037-1:2008.

Overview

EN 15037-4:2010/FprA1 is a European Standard developed by the European Committee for Standardization (CEN) that specifies requirements and basic performance criteria for expanded polystyrene (EPS) blocks used in beam-and-block floor systems. These EPS blocks are integrated with precast concrete beams compliant with EN 15037-1, for the construction of durable, efficient beam-and-block flooring structures. The standard addresses EPS blocks either entirely composed of EPS or combined with other materials such as plaster or wood wool, provided these additional materials do not exceed 50% of the block's mechanical resistance contribution.

This amendment (FprA1) focuses on clarifying requirements related to reaction to fire classification and the management of dangerous substances, ensuring that EPS blocks meet the necessary regulatory and safety standards across European markets. It also outlines conformity assessment procedures to facilitate CE marking.

Key Topics

• Material Composition: Defines EPS blocks either purely made of expanded polystyrene or combined with other materials if they comply with mechanical resistance limits.
• Performance Criteria: Covers mechanical resistance, dimensional stability, durability, and reaction to fire, essential for structural safety and longevity.
• Reaction to Fire: Requires manufacturers to declare Euroclass fire reaction performance in accordance with EN 13501-1, commonly observing EPS blocks classified as E or F. Ignitability testing follows EN ISO 11925-2 standards.
• Dangerous Substances: Addresses national regulations and verification requirements related to hazardous substances released by EPS blocks, with guidance on handling declarations when harmonized European methods are unavailable.
• Conformity Assessment: Specifies various systems (1, 2+, 3, 4) for attestation of conformity including factory production control, initial testing, continuous surveillance, and certification, enabling manufacturers to CE mark products accordingly.
• Harmonization: Aligns with relevant EU Directives and includes reference to Commission Decisions facilitating compliance across EU member states.
• Annexes and Testing Protocols: Provides detailed procedures for testing fire reaction and mechanical properties, with amendment updates refining normative references and clauses.

Applications

EN 15037-4:2010/FprA1 is critical for manufacturers, designers, and contractors involved with:

• Beam-and-block floor systems construction where EPS blocks are used for lightweight infill or insulation purposes.
• Enhancing thermal and acoustic insulation in floor assemblies while maintaining structural integrity.
• Ensuring fire safety performance in precast concrete flooring systems, especially in residential, commercial, and industrial buildings.
• Compliance with European regulations for construction products, enabling free market access through CE marking.
• Quality assurance through standardized testing and factory control, supporting product reliability and regulatory conformity.
• Designing composite floor systems that balance mechanical performance with material efficiency and sustainability considerations.

Related Standards

• EN 15037-1: Specification for precast concrete beams used in beam-and-block floor systems.
• EN 15037-5: Covers lightweight blocks for simple formwork where EPS is combined with other materials contributing beyond 50% mechanical resistance.
• EN 13501-1: Fire classification of construction products and building elements, used for Euroclass reaction to fire declarations.
• EN ISO 11925-2: Ignitability testing for materials subjected to direct flame impingement, essential for fire safety compliance.
• EU Construction Product Regulation (CPR) 305/2011: Governs the marketing of construction products in the EU with CE marking requirements.
• Additional national standards: Pertinent for addressing dangerous substances and local fire safety regulations, informing testing and documentation protocols.

---

Compliance with EN 15037-4:2010/FprA1 ensures that EPS blocks used in beam-and-block floor systems meet essential mechanical, thermal, and safety requirements. This promotes standardized, safe, and high-quality flooring solutions across the European construction sector, supporting innovation and sustainability in precast concrete applications.
