AS 1530.3 Methods for fire tests on builing materials,components and structures  Part3: Simutaneous determination of ignitability, flame propagation,heat release and smoke release

1.1  SCOPE

This Standard sets out a test method for the assessment of building materials nd components avvording to-

(a)their tendency to ignite;

(b)their tendency to propagate;

(c)the heat they release once ignition has occurred;and

(d)the tendency to release smoke.

NOTE:A guide to the interpretation of the tesults of this test,together with a full list of references,is given in Appendix A.

1.2 OBJECTIVES

The objective this standard is to establish a test method for assessing the potential fire hazard of wall linings during the early growth of fire in a compartment.the test method also provides a discriminating or ranking assessment of potential fire hazard between a range of matarials used in buildings.

1.3 APPLICATION

This Standard will be referenced in the building code of Australia (BCA) by way of BCA Amendment No.6 to be published on 1 January 2000,thereby superseding the previous edition, AS 1530.3-1989,Whick will be withdrawn 12 months from the date of publication of this edition.

1.4 PRINCIPLE

The specimen is held in a vertical configuration in a plane parallel to a radiant heater and the specimen moved towards the heater,in steps,over a period of min or until ignition, induced by a pilot flame,occurs.
