Summarise this standard

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.

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.

Originated as AS 1720.4-1990.
Previous edition 2006.
Jointly revised and redesignated as AS/NZS 1720.4:2019.
