2009. Simplified strenght properties assessment for tropical hardwoods in view to CE marking.
In : 2nd International Scientific Conference on Hardwood Processing, 2009 September 28th-29th, Paris
Résumé : Visual method (mostly used) using rules specified in national standards (NF B 52-001, BS 5756, and NPR 5493) is available for 36 tropical hardwood species in order to be use in construction. Anyway, experiments can not be done for all tropical hardwood species in due time of CE marking which will be effective in the EEC market. For a certain amount of other tropical hardwood species of moderate use, simplified rules given in EN 384 have been used to derive strength properties. They are based on bending tests on small clear specimens and on full size specimens. The relationship has been applied for a lot of species to reach CE marking as well (more than 100 species). In addition, a simplified grading visual rule is proposed. Results are presented to CEN TC 124/TG1 in order to get the strength class assignment approval.
