EN 1195:1997

Overview

EN 1195:1997 - "Timber structures - Test methods - Performance of structural floor decking" (adopted as SIST EN 1195:2000) is a CEN test standard that defines how to determine the performance of structural floor decking made from timber products when subjected to specified loading. The scope covers decking constructed from boards, laminated boards or wood‑based panel products supported on timber joists, and addresses behaviour under both concentrated static loads (e.g., people, furniture, equipment) and impact loads (e.g., human motion).

Key Topics

• Test methods for evaluating the structural performance of timber floor decking.
• Assessment of decking under specified concentrated static load and specified impact load.
• Coverage of decking types: solid boards, laminated boards and wood‑based panel products supported on timber joists.
• Measurement goals typically include load capacity, resistance to impact, and serviceability indicators such as deflection and durability under dynamic actions (standard defines how these are measured; consult the full text for procedures).
• Standardization intent: provide reproducible, comparable test results to assess performance and support design, certification and quality control.

Applications

Who uses EN 1195:

• Structural and timber engineers validating floor system performance.
• Flooring and panel manufacturers developing or certifying timber decking products.
• Independent testing laboratories performing conformity and product performance tests.
• Architects and specifiers selecting timber floor systems for residential and commercial buildings.
• Building control authorities and certification bodies evaluating compliance with performance requirements.

Practical uses:

• Verify that a timber decking assembly meets required static load and impact load performance for intended use (e.g., occupied spaces, office or residential loading).
• Support product datasheets, declarations of performance and third‑party certification.
• Inform design decisions where serviceability and occupant-induced impact (human motion) are critical.
• Compare different decking materials and constructions using standardized test results for reliable selection.

Related Standards

• EN 1195 is part of the family of timber structures test and design standards published by CEN. Users commonly apply it alongside national building regulations and other EN standards for timber design and laboratory testing to demonstrate compliance and to integrate test results into structural design.
