African Padauk (Pterocarpus soyauxii) and Niove (Staudia kamerunensis) were tested in laboratory against Basidiomycetes. The results were calculated according to the requirements of EN 350-1 (1994) and XP CEN/TS 15083-1 (2006). Padauk samples showed a high durability and very small variations between trees and within tree. Niove presented a high durability, but with notable differences according to the calculation of the results. This paper is underlining the importance of the sampling, the test method, and the calculation of the results for the qualification of timber. This is of importance considering that the EN 350-2 standard is under revision and that different timbers (secondary species, plantation timbers,...) are available on the market.
