ISO DIS 12122-4

Description / Abstract: This International Standard gives methods of determination of characteristic values for a defined population of engineered wood products, calculated from test values.

It presents methods for the determination of:

a) characteristic value of material properties, where the determined property is multiplied by a geometric parameter to give a component capacity or component stiffness, or

b) characteristic value of component properties directly, where the determined property is a component capacity or component stiffness.

It presents methods for determination of:

a) characteristic value of mean-based properties, and

b) characteristic value of 5th percentile-based properties.
