Describes 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.

On the basis of test results from wood-based panel products for structural purposes, this European Standard 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.

Test data should be determined from tests using the test methods outlined in EN 789.
