EN113, EN113-3, NF B51-295, ST-056 from the SNCF, XP ENV 12038

These various standardised tests aim to assess the resistance of panels (treated or untreated) to basidiomycete wood-decay fungi (wood-rotting fungi). These tests enable manufacturers to obtain an accredited standardised test report, with an assessment of their panel's resistance to rot fungi, for use in service class 3 (XP ENV12038 test) or for use in railway carriage flooring (NF B51-295 test) as required in technical specifications ST056.

Standard NF B51-295:
This laboratory test standard is applicable to wood-based panels, particularly for use in railway carriage flooring.
Panel test pieces are first artificially aged, then exposed to various pure cultures of basidiomycete fungi for several weeks. Resistance coefficients are calculated following bending tests on the panels. The resistance of the panels to rot fungi is based on a comparison of the bending results before and after exposure to the fungi.

XP ENV 12038 method :
This test standard allows the resistance of wood-based panels to wood-decaying basidiomycete fungi to be assessed. Panel test specimens are first artificially aged and then exposed for 16 weeks to pure cultures of fungi such as Coniophora puteana and Pleurotus ostreatus for all types of panels.
More specific fungi are also tested depending on the type of wood used in the panels. The percentage of mass loss caused by the fungi is used to assess the resistance of the panels.

Method EN113-3:
This method will replace method XP ENV12038.
