Specifies requirements for the design, construction and installation of fire-resistant doorsets including transom panels but excluding lift-landing doors and access panels, used to protect openings in walls and partitions required to resist the passage of fire. Shows the variation between Australia and New Zealand in regard to the certification, marking and identification of doorsets as determined by the building codes and practice in both countries. A series of tests by which the physical capacity of the doorsets may be measured is also included.
Scope
This Standard specifies requirements for the construction and installation of fire-resistant doorsets used to protect openings in walls and partitions which are required to resist the passage of fire.
This Standard also applies to transom panels over doors, where the panels are contained within the doorframe and form part of the doorset.
This Standard does not apply to lift-landing doors.
NOTES:
1 Where it is intended to install the fire-resistant doorset in high traffic areas, it is recommended that it be tested in accordance with Appendix A prior to fire testing and that it complies with the requirements set out therein.
2 Durability designations for locksets and methods for their cycle testing, for minimal, moderate and high frequency usage, are given in AS 4145.2.
3 Manufacturers of fire-resistant doorsets are strongly encouraged to implement quality control systems in accordance with AS/NZS ISO 9002.
Guidance on the introduction and maintenance of suitable quality systems is given in AS/NZS ISO 9000 and AS/NZS ISO 9004.
4 Guidance on information that should be supplied with an enquiry or order is given in Appendix B.
5 Requirements governing lift-landing doors are given in AS 1735.11 or NZS 4332P, as applicable.
6 A panel above a doorset, which is not contained within the door frame, is considered as being part of the wall and is therefore subject to the structural adequacy, integrity and insulation requirements set out in the Building Code.
7 A transom or mullion within a door frame may be permanently fixed to the side members of the frame or may be removable by means of mechanical fixing.
8 A smoke control system (or other external environmental conditions) can impose forces greater than 5 N on the strike. In such circumstances a substantially greater resistance force may be required of the strike to ensure the door remains in the latched position during a fire emergency.
