Precast concrete products – Classification of glassfibre reinforced concrete performance – EN 15191:2025

EN 15191:2025 is a European standard that focuses on the classification of glassfibre reinforced concrete (GRC) performance, specifically for precast concrete products. This standard is crucial for ensuring that GRC components meet the necessary performance criteria during the design and manufacturing processes.

Scope of EN 15191:2025

The scope of EN 15191:2025 includes the following key aspects:

1. Classification of Glassfibre Reinforced Concrete: The standard provides a framework for classifying the performance characteristics of GRC. This classification is essential for designers and manufacturers to understand the material’s capabilities and limitations.
2. Application in Precast Concrete Products: EN 15191:2025 is specifically tailored for precast concrete products, which are widely used in construction for their efficiency and versatility. The standard ensures that these products meet specific performance standards, enhancing their reliability and safety.
3. Design Process Integration: The standard is designed to be integrated into the design process of GRC components. It does not cover design methods but focuses on the classification of performance, which is critical for engineers and architects involved in the design of precast concrete structures.
4. Compliance with Related Standards: EN 15191:2025 is intended to be used in conjunction with other relevant standards, such as EN 1169, which outlines the general requirements for GRC. This ensures a comprehensive approach to the classification and performance assessment of GRC products.

Updates from Previous Versions

The 2025 version of EN 15191 introduces several significant updates compared to its predecessor, EN 15191:2010:

1. Refined Classification Criteria: The new version enhances the classification criteria for GRC, providing clearer guidelines and more detailed performance categories. This refinement helps manufacturers and designers better understand the material’s properties and how they can be applied in various construction scenarios.
2. Improved Testing Methods: EN 15191:2025 incorporates updated testing methodologies that reflect advancements in material science and engineering. These improvements ensure that the performance assessments of GRC are more accurate and reliable.
3. Focus on Sustainability: The 2025 standard places a greater emphasis on sustainability and environmental considerations in the use of GRC. This aligns with the growing trend in the construction industry towards more sustainable practices and materials.
4. Alignment with International Standards: The updated standard aims to align more closely with international standards, facilitating easier adoption and implementation across different countries. This is particularly important for multinational construction projects where compliance with various standards is necessary.
5. Enhanced Guidance for Manufacturers: The new version provides more comprehensive guidance for manufacturers regarding the production and quality control of GRC products. This is crucial for ensuring that the final products meet the specified performance criteria.

Countries Utilizing EN 15191:2025

EN 15191:2025 is primarily utilized in European countries, as it is a European standard. However, its relevance extends beyond Europe due to the globalization of construction practices and the increasing importance of performance-based standards. Some of the countries that are likely to adopt and utilize this standard include:

1. Germany: Known for its rigorous construction standards, Germany is likely to incorporate EN 15191:2025 into its national regulations, particularly in the precast concrete sector.
2. France: France has a strong focus on quality and safety in construction, and the adoption of EN 15191:2025 will enhance its existing regulations for precast concrete products.
3. United Kingdom: Although the UK has its own set of building regulations, the principles outlined in EN 15191:2025 may influence future updates to these regulations, especially in relation to precast concrete.
4. Italy and Spain: Both countries have a significant precast concrete industry, and EN 15191:2025 will likely be referenced in their building codes to ensure compliance with European standards.
5. Scandinavian Countries: Countries like Sweden, Norway, and Denmark are known for their commitment to quality and sustainability in construction. EN 15191:2025 will be relevant in these countries as they continue to develop their building regulations.

In conclusion, EN 15191:2025 represents a significant advancement in the classification of glassfibre reinforced concrete performance for precast concrete products. Its comprehensive scope, updated methodologies, and alignment with international standards make it a crucial document for ensuring the quality and safety of precast concrete structures across Europe and beyond. As the construction industry increasingly prioritizes performance and sustainability, the adoption of EN 15191:2025 will play a vital role in enhancing the reliability and efficiency of precast concrete products worldwide.
