ISO 12122-5:2018 (R2024)

This document gives methods of determination of characteristic values for a defined population of mechanical connections between timber components, calculated from full scale test values. It presents methods for the determination of: a) slip modulus of mechanical connections; b) characteristic strength of connections subjected to either monotonic or cyclic loads. Glued connections are excluded from the scope of this document. NOTE 1 It is assumed that the failure mode is the same for all specimens in the sample. NOTE 2 When a small number of test results is available, ISO 12122-6 is used for the determination of the mean and the 5th percentile values. NOTE 3 Informative commentary to the clauses of this document can be found in Annex A.
