    Abstract - (Show below) - (Hide below)

    Specifies structural property, marking and physical requirements for mechanically stress-graded timber. Physical requirements are given for strength considerations as well as for utility considerations.

    Scope - (Show below) - (Hide below)

    This Standard specifies mechanical property requirements, marking requirements and physical requirements for mechanically stress-graded timber.NOTES:1 The stress-grading machine sorts the timber on the basis of its modulus of elasticity.2 Appendix A provides commentary. Appendix B provides information on the means for demonstrating compliance with this Standard.
