BS EN 336:2013

Comprehensive Structural Timber Standard

BS EN 336:2013 is the essential British Standard for specifying the dimensions and permissible deviations of structural timber products. Developed by the European Committee for Standardization (CEN), this standard ensures consistent quality and compliance for construction projects across the UK and Europe.

Key Specifications

- Covers sawn and processed softwood and hardwood timber- Defines standard sizes, lengths, and cross-sectional dimensions- Outlines permissible deviations for key measurements- Applicable for structural, load-bearing, and general construction uses- Harmonized with other relevant EN standards for timber products

Benefits of Compliance

- Ensures structural integrity and safety of timber components- Enables consistent procurement and supply chain management- Facilitates accurate estimation, planning, and construction- Supports compliance with building regulations and codes- Promotes quality, reliability, and performance of timber structures

Technical Details

BS EN 336:2013 specifies the following for structural timber:- Nominal cross-sectional dimensions and lengths- Permissible deviations for: - Width and thickness - Length - Squareness - Straightness - Twist- Moisture content requirements- Grading and strength class designationsThe standard also covers the measurement methods and procedures for verifying dimensional compliance.

Applications and Use

This British Standard is an essential reference for architects, engineers, builders, and timber suppliers involved in construction projects. It provides the technical specifications required to:- Select appropriate structural timber products- Ensure accurate cutting, fitting, and installation- Maintain quality control and dimensional tolerances- Demonstrate compliance with building regulationsWhether you're working on residential, commercial, or industrial developments, BS EN 336:2013 helps you deliver timber structures that are safe, reliable, and fit for purpose.
