Wood-based panels. Determination of characteristic 5-percentile values and characteristic mean values. | Status: Current

1 Scope 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 the test standard EN 789 or other relevant test standard, performance standard or product standard normatively referring to EN 1058.

NOTE See e.g. EN 1195 and EN 12871.

The statistical evaluation follows the principles of EN 1990:20231, Annex D of EN 1995‑1‑1:20042 and of EN 14358:2016.
