An Available Superseded Standard is one, which has been made available for a period of time although it has been formally superseded by another Standard. Its availability is maintained where it is referenced in legislation/regulations or in other Standards and its use should be restricted to where so referenced. No responsibility is taken by Intertek Inform as to the ongoing technical validity of such a Standard, the responsibility resting with the referencing authority.

Provides a computational method for determining the fire-resistance of solid and glued-laminated structural timber members as an alternative to furnace testing. Information is also provided on methods of protecting timber and metal connectors from the effects of fire.

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.
