== Abstract ==

This paper presents a study of the flexural test, simply supported and two spans, necessary to establish the acceptance criteria of a sandwich panel of faces derived from wood, subjected to uniform load.
Tests have been carried out on sandwich panels with CE marking and all of them have passed the European Technical Approval (ETA) evaluation process for the use for which they are specified.
The results obtained in the experimental tests have been compared with analytical models and with finite element models. It has been observed that the finite element models coincide with the experimental results as long as the properties of the constituent materials of the sandwich panel are accurately known and the boundary conditions are suitably modeled.
The analytical model also matches the finite element model when ideal supports are modelled.
