This Malaysian Standard specifies the requirements for assessing and operating machine strength grading systems, to strength grade structural timber and laminates for glulam.
NOTE. Whilst it is permitted to use this standard to determine machine settings and to grade to any possible strength profile for a given species, this standard refers to the strength classes/groups of MS 544 to provide suitable strength profiles and dictate the visual override requirements necessary to make a machine grading to this standard possible. In addition, guidance is given for the degree of quality control necessary to ensure the reliability of timber graded by strength grading machines. These requirements are given for ‘machine-controlled’ system for grading timber.
