This Standard provides a computational method for determining the fire-resistance of solid and glued-laminated structural timber members as an alternative to testing in accordance with AS 1530.4.This Standard also provides guidance on methods for protecting metal connectors from the effects of fire.NOTES:1. This Standard is not relevant to the determination of the early fire hazard properties of materials for which a method of assessment is given in AS 1530.3.2. This Standard is not relevant to structural accreditation through furnace testing for which the appropriate Standard is AS 1530.4.
