scope:

This Standard describes procedures for the initial evaluation and daily quality control requirements necessary to verify that timber has the structural properties claimed for it. The procedures apply to timber that is both visually and machine stress graded.

A suitably qualified organization shall carry out the initial evaluation to establish the particular grades of timber a mill is capable of producing. The same, or another, suitably qualified organization shall undertake audits of the mill's daily quality controls to ensure timber continues to be produced to the claimed grades.

The adequacy of the suitably qualified organizations needs to be ascertained but is outside the scope of this Standard. 

This Standard does not apply to naturally round timber, glue-laminated timber, plywood, or to laminated veneer lumber (LVL). It provides a basis for verification that timber has the characteristic properties of the grade. 

This Standard is intended for use by producers of verified stress graded sawn timber products. Assessment of compliance is to apply at the plant gate.
