What is EN ISO 9386-2:2014

The EN ISO 9386-2:2014 is an international standard that provides guidelines and specifications for the mechanical performance of full-scale joints in timber structures. It focuses specifically on the testing and evaluation of dowel-type fasteners, such as nails, screws, and bolts, used for structural connections in timber construction.

Importance of EN ISO 9386-2:2014

EN ISO 9386-2:2014 plays a crucial role in ensuring the safety and reliability of timber structures. By providing standardized testing methods, it enables engineers and designers to accurately assess and compare different fastener systems, ensuring that they meet the required strength and durability criteria.

This standard also helps builders and contractors choose appropriate connectors for their timber projects, reducing the risk of structural failures caused by inadequate or inappropriate fasteners.

Key Elements of EN ISO 9386-2:2014

The EN ISO 9386-2:2014 standard covers various aspects of dowel-type fasteners in timber structures. It includes requirements for testing materials, preparation of test pieces, loading methods, and acceptance criteria for evaluating the mechanical properties of the connections.

One key element is the determination of the ultimate withdrawal resistance of the fastener from the timber. This test measures the force required to pull the fastener out of the wood parallel to the grain and provides valuable information about the holding capacity of the connection.

Another important aspect covered by this standard is the assessment of slip modulus. It measures the ability of a connector to resist relative movement between connected members, indicating its ability to maintain structural integrity under various loads and conditions.

Conclusion

The EN ISO 9386-2:2014 standard serves as an essential tool for the timber construction industry. It ensures that timber structures are built using reliable and tested fasteners, promoting safety and durability. Compliance with this standard guarantees that connections in timber constructions meet the required mechanical performance standards, leading to a more sustainable and resilient built environment.
