BS EN 13377:2002 standard provides guidelines for the classification, requirements, and assessment procedures of prefabricated timber formwork beams. The standard also includes information on production control requirements.

These prefabricated timber formwork beams are designed for use in falsework and formwork systems, with the load applied in the direction of the beam depth. The beams are constructed using glued I-shaped components, consisting of two identical flange members made of solid timber, connected by a single web of wood-based material. The standard specifies three different beam depths: 160 mm, 200 mm, and 240 mm.

The beams can also be connected by a lattice of solid timber members, but in this case, the beam depth is fixed at 240 mm. The standard outlines the necessary criteria for the beams to meet in terms of their classification, performance requirements, and assessment procedures. Additionally, it provides guidance on the quality control and production processes to ensure the consistent and reliable performance of these prefabricated timber formwork beams.
