What is
EN14889-2:2006 Certification?

Scope:

This standard applies to macro synthetic fibres intended to be used as reinforcement in concrete. It does not cover microfibers or other types of reinforcement.

​

Classification:

Fibers are classified based on their physical properties, including length, diameter, and material composition. Macro synthetic fibres generally have a length greater than 30 mm and a diameter of 0.3 mm or more.

​

Performance Requirements:

• Tensile Strength: Specifies the minimum tensile strength of the fibres to ensure they provide adequate reinforcement.

• Aspect Ratio: The ratio of fibre length to diameter, which influences the effectiveness of the fibres in the concrete matrix.

• Elongation at Break: Defines how much a fibre can stretch before breaking, important for flexibility and durability.

 

Testing Methods:

Outlines standardized methods for testing the properties of fibres, including:

• Tensile Tests: To measure the strength and elasticity.

• Impact Resistance Tests: Evaluates how well the fibre-reinforced concrete can absorb and dissipate energy during impact.

• Flexural Strength Tests: Measures the concrete's resistance to bending, crucial for structural applications.

• Durability Tests: Assesses how fibres perform under various environmental conditions over time.

​​

Marking and Documentation:

Requirements for labelling and documentation to ensure traceability and compliance with the standard. This includes information on the manufacturer, batch number, and compliance with the standard.

 

Quality Control:

Emphasizes the importance of quality control in the manufacturing process to ensure that all fibres meet the specified standards consistently.

 

Applications

Macro Synthetic fibres covered by this standard are used in various concrete applications, including:

• Industrial floors, pavements, and slabs where crack resistance is critical.

• Shotcrete applications in tunnels and underground structures.

• Infrastructure Projects such as roads, and bridges where increased structural integrity is essential.

• Precast concrete elements to enhance overall durability and performance.

 

Importance of Certification

Quality Assurance:

Certification under EN 14889-2:2006 ensures that fibres meet established quality and performance benchmarks, providing confidence in their use.

Regulatory Compliance:

Helps manufacturers and contractors comply with European regulations, facilitating the acceptance of products in various markets.

Performance Consistency:

Guarantees that the fibres will perform as intended in concrete applications, which is vital for safety, longevity, and structural integrity.

Market Confidence:

Increases trust and confidence among contractors, engineers, and end-users, as it indicates that the product has been tested and meets industry standards.

 

Conclusion

EN 14889-2:2006 certification plays a critical role in the construction industry by setting clear standards for macro synthetic fibres. By ensuring that these fibres meet defined specifications, the standard contributes to the durability, safety, and performance of concrete in various applications. Compliance with this standard helps manufacturers, contractors, and engineers make informed decisions regarding the materials they use, ultimately enhancing the quality of construction projects.
