Sylvatest

Sylavtest is an ultrasonic measuring device that provides an overall diagnosis of a wooden component to test its mechanical strength. This is a specific non-destructive testing tool for wooden beams.

Timber Beam Strength Test

Description

Sylvatest is an acousto-ultrasonic measuring device that provides an overall diagnosis of the wood element, based on the speed and energy absorption of the transmitted ultrasonic wave.[1][2][3] The result given reflects the residual health of the wood in the trunk of the tree tested or the beam measured. These are non-destructive tests.[4][5]

The technology was developed by Professor Jean-Luc Sandoz as part of his thesis at EPFL in 1984 and was further developed by researcher Yann Benoit in 1998.[4][6]

Grading by ultrasound

Applications

The sylvatest is used in many countries (Brazil, Europe and Asia).[4][7][8][9][10]

It has been used on historic buildings such as the Entrepôts des magasins généraux in Paris, the Forbidden City in Beijing, and the beams of Notre-Dame de Paris[11][12] or even the Château de Valère.[13]

It is also used to certify the quality of wood for registered designations of origin such as Bois des Alpes[14][15] or Bois de Chatreuse.[16][17]
