Overview

EN 595:1995 is a European standard developed by CEN that defines the test methods for evaluating timber trusses. The standard focuses on establishing reliable procedures to determine the strength and deformation behaviour of timber trusses under various loading conditions. It ensures consistent testing practices across the timber construction industry, facilitating accurate assessment of structural performance.

This standard references and builds upon the test principles outlined in EN 380, providing detailed methodologies specifically tailored to the unique properties of timber trusses. By standardizing test procedures, EN 595 enhances the safety, reliability, and quality control of timber structures used in construction.

Key Topics

• Test Procedures: Describes step-by-step methods for conducting physical tests on timber trusses to evaluate their structural integrity.
• Strength Determination: Covers the measurement of maximum load-bearing capacity before failure occurs, crucial for design validation.
• Deformation Behaviour: Addresses the assessment of truss deflections and displacements under load to understand stiffness and serviceability.
• Test Setup and Instrumentation: Specifies requirements for load application, support conditions, and instrumentation to ensure accurate measurement.
• Safety Considerations: Outlines precautions during testing to protect personnel and equipment while ensuring test validity.
• Correlation with EN 380: Extends general timber testing principles to truss-specific applications, harmonizing methodologies.

Applications

EN 595:1995 is essential for professionals involved in the design, manufacturing, and quality control of timber structures, including:

• Structural Engineers: Use the standard to validate design assumptions and ensure compliance with safety requirements.
• Manufacturers of Timber Trusses: Employ testing procedures to certify product performance before market release.
• Construction Firms: Reference test results to guarantee the reliability of structural components used in buildings.
• Certification Bodies: Apply the standard for assessing conformity and issuing certifications for timber structural elements.
• Research and Development: Facilitate development of new timber truss designs and materials through standardized performance evaluation.

The standard supports the development of robust timber structures capable of meeting modern construction demands while maintaining sustainability and resource efficiency.

Related Standards

• EN 380 – General test methods for timber, which provides foundational testing principles used and expanded upon in EN 595.
• EN 1995 (Eurocode 5) – Design of timber structures, complementary to EN 595 by providing design calculations informed by test data.
• EN 408 – Strength and stiffness of structural timber and glued laminated timber, which may be used in conjunction with truss tests.
• EN 1990 – Basis of structural design, providing overarching principles relevant to testing and analysis.

By adhering to EN 595:1995, stakeholders ensure that timber trusses are tested under standardized conditions, promoting confidence in structural safety, durability, and performance. This enhances the credibility of timber constructions within the building industry and supports sustainable development goals by optimizing the use of renewable wood resources.
