On the basis of test results from wood-based panel products for structural purposes, this document specifies a method for the determination of:
— characteristic 5-percentile values of mechanical properties under the assumption of a log-normal distribution of the test data according to EN 14358; and
— characteristic mean values (50-percentile values) of physical properties under the assumption of a normal distribution of the test data according to EN 14358.
Test data can be determined from tests using the test methods outlined in test the standard EN 789 or other relevant test standard, performance standard or product standard normatively referring to prEN 1058.
NOTE See e.g. EN 1195 and EN 12871.
The statistical evaluation follows the principles of Annex D of EN 1990:2002, of EN 1995-1-1:2004, Eurocode 5: Design of timber structures — Part 1-1: General — Common rules and rules for buildings, and of EN 14358:2016, Timber structures. Calculation and verification of characteristic values.

This document specifies the requirements for softboards as defined in EN 316, with a density from 230 kg/ m3 to 400 kg/ m3.
The values listed in this document relate to product properties but they are not characteristic values to be used in design calculations.
NOTE Panels which are intended for use exclusively as thermal insulating products are covered by EN 13171.
