To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may a
16、lso be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased. Detailed information about joint Australian/New Zealand Standards can be found by visiting the Stand
17、ards Web Shop at .au or Standards New Zealand web site at www.standards.co.nz and looking up the relevant Standard in the on-line catalogue. Alternatively, both organizations publish an annual printed Catalogue with full details of all current Standards. For more frequent listings or notification of
18、 revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options. For information about these services, users should contact their respective national Standards organization. We also welcome suggestions for improvement in our Standards, and espec

23、A on 03 Jun 2008 AS/NZS 1668.1:1998 2 PREFACE This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee M-062, Ventilation and Airconditioning, to supersede AS 1668.11991, The use of mechanical ventilation and air-conditioning in buildings, Part 1: Fire and smoke co
24、ntrol. This Standard incorporates Amendment No. 1 (November 2002). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected. There is a considerable body of fire research which indicates th
25、at when a fire occurs in a multi-compartment building, the smoke from the fire is a far greater hazard to occupant safety than the fire itself, i.e., (a) Smoke obscures vision, preventing occupants from finding safe escape routes. (b)Smoke hinders the fire brigade in its search and rescue operations
26、. (c) Smoke can kill by asphyxiation or by poisoning people well before the temperature of the fire or smoke causes injury. The fundamental purpose of this document is, therefore, life safety. Its objective is to provide standardized minimum requirements for mechanical air-handling and mechanical sm
27、oke control systems for use by designers, installers, inspectors and regulators of these systems. The Standard does not identify those buildings in which smoke control systems or pressurization systems are required. This is covered in the Building Code of Australia (BCA) or the New Zealand Building
28、Code Handbook and approved documents, as applicable. The first edition of AS 1668.1, published in 1974, prescribed a smoke control system intended to restrict the movement of smoke by way of airconditioning and ventilation ducting within a multistorey office building. This philosophy did not address
29、 smoke movement in a building by way of paths other than the air-handling system. Since the original publication, the Standard has changed, the zone pressurization system was added and the Standard has been applied (correctly and incorrectly) to buildings other than multistorey offices. The objectiv
30、e of the Standard has also been expanded to limit smoke spread in a building by way of paths other than simply the ductwork. This revision looks deeper into the application of the Standard within buildings with varied uses, offers designers more options to find solutions for particular building type
31、s and further clarifies the intended application of the Standard. The main technical changes made in this edition can be summarized as follows: (i) Five particular methods of active smoke control have been included, with a table indicating which one The Standard has been linked to AS 1670.1. (ii) Mo
32、re comprehensive testing clauses have been included. (iii) Requirements for power and indication wiring and smoke detection for system control have been revised. (iv) Requirements for non-electrical control systems have been added. (v) Recommendations on reliability have been included because of con
33、cerns over the long-term operational capabilities of highly complex systems. (vi) Protection of small exhaust duct penetrations in fire compartmentalization walls may now be by subduct rather than by fire dampers due to damper maintenance problems.

A normative appendix is an integral part of a Standard, whereas an informative appendix is only for information and guidance. Statements expre
35、ssed in mandatory terms in notes to tables are deemed to be requirements of this Standard. Figures provided in this Standard are informative. This Standard incorporates a Commentary on some of the clauses. The Commentary directly follows the relevant Clause, is designated by C preceding the clause n
36、umber and is printed in italics in a panel. The Commentary is for information only and does not need to be followed for compliance with the Standard.
