ISO 12122-4:2017 gives methods of determination of characteristic values for a defined population of engineered wood products calculated from test values.This document presents methods for the determination ofa) characteristic value of material properties, where the determined property is multiplied by a geometric parameter to give a component capacity or component stiffness, orb) characteristic value of component properties directly, where the determined property is a component capacity or component stiffness.ISO 12122-4:2017 presents methods for determination ofa) characteristic value of mean-based properties, andb) characteristic value of 5th percentile-based properties.
