8、This Standard was prepared by the Standards Australia/Standards New Zealand CommitteeEL/37 on Special Wiring Systems to supersede AS 3013 1990, Electricalinstallations Wiring systems for specific applications. This Standard provides a systemof classification and testing of the degree of protection i

9、nherent in a wiring system withregard to fire and mechanical damage.This revision was undertaken in order to include requirements for busways. It is intendedthat at the next revision the Committee will consider the results of further testing ofwiring systems and will cover all aspects of the Standar

10、d including:(a) The methods used to perform the fire test and the fire with water test; and(b) The means of classifying and identifying complete wiring systems.The need to maintain circuit integrity in buildings, oil rigs, ships, and other structuresunder fire conditions is most important for wiring

11、 systems associated with firefighting,evacuation, and other safety functions.While there are some Standards available for fire testing of cables (e.g. IEC 331, Fire-resisting characteristics of electric cables; IEC 332, Tests on electric cables under fireconditions;andBS 6387, Specification for perf

12、ormance requirements for cables requiredto maintain circuit integrity under fire conditions), it was considered that these did notform an adequate basis for a system of classification. For this reason, AS 1530.4,Fire-resistance test of elements of building construction has been used as the basis of

13、firerating of wiring systems in this Standard. Testing in a horizontal furnace has beenprescribed since it was considered that this represents the most onerous condition.This Standard provides a system of classification of the degree of protection inherent inwiring systems against accidental mechani

14、cal damage. It does not consider protectionagainst deliberate tampering. The levels of mechanical protection are specified in terms ofimpact energies and cutting forces.Statements expressed in mandatory terms in notes to tables and figures are requirementsof this Standard.Appendices designated as no

15、rmative are essential to the understanding orimplementation of this Standard. Appendices designated as informative give additionalinformation, recommendations, guidelines or other non-mandatory statements.

25、ECTION 1 SCOPE AND APPLICATION1.1 SCOPE This Standard sets out a classification system for wiring systems accordingto their ability to(a) maintain circuit integrity under fire conditions for a specified period; and(b) maintain circuit integrity against mechanical damage of specified severity.It spec

26、ifies type tests to determine the performance of the various types of wiring system.NOTE: Elements of a wiring system may need replacement after exposure to a hazard.1.2 APPLICATION This Standard applies only to wiring systems that are in all otherrespects safe and suitable for their intended use an

27、d comply with other relevant Standards.The use of wiring systems tested in accordance with this Standard may not be necessarywhere elements of building construction provide satisfactory protection against the effectsof fire and mechanical damage.NOTES:1 The degree of protection against fire and mech

28、anical damage required of a wiring system isdependent on the application. To determine specific requirements, reference should be madeto Standards dealing with a particular application. (See Appendix G, Paragraph G2.)2 Appendix G describes methods of protection of wiring systems against the hazards

29、of fire ormechanical shock for which testing may not be considered necessary.1.3 REFERENCED AND RELATED DOCUMENTS1.3.1 Referenced documents The following documents are referred to in this Standard:AS1074 Steel tubes and tubulars for ordinary service1530 Methods for fire tests on building materials,
