The timber grades, species and sources listed meet the requirements of the strength classes to which they are assigned in Table 1 and Table 2. Table 3 and Table 4 identify the botanical species for the commercial names listed in Table 1 and Table 2. NOTE 1 Timber graded by machine to EN 14081 may be graded directly to the strength classes and marked accordingly, and is therefore not referenced in this document. NOTE 2 For combinations of species and visual grades which meet the requirements of EN 14081 but are not listed in this standard, the assignment to strength classes can be made according to EN 338 using characteristic values determined in accordance with EN 384. The accepted assignments to strength classes given in this European Standard are based on initial type testing (ITT) and initial type calculation (ITC). The ITT and ITC documentation from the manufacturers has been evaluated by CEN/TC124/WG2/TG1 and the accepted values given in an ITT report. This report is the basis for the attestation of conformity by the Notified Body conducting the certification of the producer’s factory production control (FPC). Further ITT reports may be used as documentation before the information they contain becomes available in an amendment or revision of this European Standard, EN 1912. SIST EN 1912:2012
