What is BS EN 314?

Introduction

BS EN 314 is a technical standard that is commonly referred to in the wood industry. It defines the requirements for plywood intended to be used in structural applications.

The Purpose of BS EN 314

The main purpose of BS EN 314 is to ensure that plywood meets specific performance criteria, particularly in terms of its bonding quality and resistance to moisture. This standard helps consumers and engineers in selecting suitable plywood for various construction projects, ensuring safety and durability.

Key Requirements of BS EN 314

There are different classes within BS EN 314, each indicating the level of performance a plywood panel must meet. The two main categories are BS EN 314-1 and BS EN 314-2.

BS EN 314-1 covers plywood panels used in dry conditions such as interior applications where humidity levels are low. These panels are not suitable for use in environments exposed to moisture over extended periods.

On the other hand, BS EN 314-2 classifies plywood panels suitable for use in humid conditions, such as external applications where exposure to moisture is more significant. These panels have better bonding quality and are designed to withstand prolonged exposure to humidity and dampness.

Testing Methods

In order to determine compliance with BS EN 314, plywood manufacturers conduct laboratory tests according to specific procedures defined in the standard.

One of the tests involves subjecting plywood samples to boiling water for an extended period of time. This helps identify how well the adhesive used in the plywood holds up under wet conditions.

Another test measures the shear strength of the plywood, which determines its ability to resist forces that can cause it to split or delaminate.

Conclusion

BS EN 314 is an essential standard that ensures the quality and suitability of plywood for structural applications. By adhering to these requirements, manufacturers can provide plywood panels that meet the necessary performance criteria, giving peace of mind to engineers and construction professionals while ensuring safety and durability in various projects.
