What is EN 14081-1:2016+A1:2019-Timber structures – Strength graded structural timber with rectangular cross section – Part 1: General requirements?
EN 14081-1:2016+A1:2019 sets out the general requirements for strength-graded structural timber with a rectangular cross-section used in timber structures. The standard applies to sawn softwood and hardwood with rectangular cross-sections, which have been strength graded by visual or machine methods.
The standard specifies the requirements for the strength grading process. Including visual grading, machine grading, and combinations of the two. It also sets out the requirements for marking, labelling, and documentation of strength-graded timber.
The standard provides information on the minimum requirements for the mechanical properties of strength-graded timber. Such as modulus of elasticity, modulus of rupture, and compression strength. It also includes requirements for moisture content, dimensions, and surface characteristics of strength-graded timber.
Therefore, EN 14081-1:2016+A1:2019 ensures that strength-graded structural timber with rectangular cross-sections used in timber structures meet the necessary safety and performance requirements.
Requirements of EN 14081-1:2016+A1:2019
· Classification of timber into strength classes based on its characteristic values for strength and stiffness
· Requirements for strength grading machines and personnel involved in grading
· Requirements for the visual grading of timber
· Requirements for the machine grading of timber
· Requirements for the determination of strength and stiffness properties of graded timber
· Requirements for marking, labelling, and documentation of graded timber
These requirements ensure that the graded timber is suitable for use in load-bearing structures, and that it meets the necessary safety and performance requirements. Moreover, the standard also provides guidance on the use of graded timber in various applications. Including construction, furniture, and packaging.
Benefits of EN 14081-1:2016+A1:2019
EN 14081-1:2016+A1:2019 provides a standardized method for strength grading structural timber with rectangular cross-section. Ensuring that the wood used in construction meets certain strength requirements. This helps ensure the safety and reliability of timber structures. As well as consistency in the properties of the wood used.
So, By using EN 14081-1, builders and manufacturers can ensure that the wood they use meets the necessary quality and safety standards, giving them peace of mind that their structures will perform as expected. Additionally, the standardization of strength grading methods can help simplify the manufacturing process and reduce costs.
Who needs EN 14081-1:2016+A1:2019-Timber structures – Strength graded structural timber with rectangular cross section – Part 1: General requirements?
EN 14081-1:2016+A1:2019 specifies general requirements for the strength grading of solid timber with rectangular cross-sections shaped by sawing or by a combination of sawing and other machining operations. Including finger-jointing, to obtain the required product size. It applies to the following solid timber products: sawn timber, glued laminated timber and solid structural timber with rectangular cross-sections.
Hence, The standard is intended for use by manufacturers, designers, specifiers, and regulatory bodies involved in the strength grading of solid timber. It may also be used by other interested parties. Such as users, testers, and researchers. To promote a common understanding of the principles of strength grading.
