- 101.1 This Standard applies to mechanically stress graded timber intended for use in structures requiring timber of predictable strength and stiffness performance. The specification covers the branding of the stress graded timber, the recommended stress grades to be adopted, the additional visual grading requirements, and dimensional tolerances for material intended to be mechanically stress graded. 101.2 Where any other Standard named in this Standard has been declared or endorsed in terms of the Standards Act 1965, then - (a) Reference to the named Standard shall be taken to include any current amendments declared or endorsed in terms of the Standards Act 1965; or (b) Reference to the named Standard shall be read as reference to any Standard currently declared or endorsed in terms of the Standards Act 1965 as superseding the named Standard, including any current amendments to the superseding Standard declared or endorsed in terms of the Standards Act 1965. NOTE — The date at which an amendment or superseding Standard is regarded as 'current' is a matter of law depending upon the particular method by which this Standard becomes legally enforceable in the case concerned. In general, if this is by contract the relevant date is the date on which the contract is created, but if it is by Act, regulation, or bylaw then the relevant date is that on which the Act, regulation, or bylaw is promulgated. 101.3 The word 'shall' is used to indicate practices which are mandatory for compliance with this Standard. The word 'should' indicates practices which are advised or recommended.
