This Schedule sets out the procedures for determining the fire hazard properties of assemblies tested to AS/NZS 1530.3.

2. Assemblies

2.1 General requirement

The fire hazard properties of assemblies and their ability to screen their core materials as required under Specfication C1.10 must be determined by testing in accordance with this Clause.

2.2 Form of test

Tests must be carried out in accordance with—

(a)

for the determination of the Spread-of-Flame Index and Smoke-Developed IndexAS/NZS 1530.3; and

2.5 Smaller specimen permitted

A testing laboratory may carry out the test specified in Clause 2.2(b) at pilot scale if a specimen (which must be not less than 900 mm x 900 mm) will adequately represent the proposed construction in the building, but the results of that test do not apply to construction larger than limits defined by the laboratory conducting the pilot examination.
