    Abstract - (Show below) - (Hide below)

    The objective of this Standard is to provide a method for determining the fire resistance for structural adequacy and insulation of sawn timber, timber in pole form, plywood, laminated veneer lumber (LVL), and glued-laminated structural timber elements as an alternative to the test method specified in AS 1530.4.

    Scope - (Show below) - (Hide below)

    This Standard provides a method for determining the fire resistance for structural adequacy and insulation of solid sawn timber, timber in pole form, plywood, laminated veneer lumber (LVL), and glued-laminated structural timber elements as an alternative to a standard fire test specified in AS 1530.4 for Australia and New Zealand; and the NZS/BS 476 series and EN 1365 series for New Zealand only.
    This Standard also provides methods for protecting metal connectors from the effects of fire.
    NOTE 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/NZS 1530.3.
    NOTE 2 The advanced calculation method in Appendix B provides guidance for an additional method of determining fire resistance.
