The term “fire rating” is very broad and can be misinterpreted and misused. Under the Building Code of Australia, the correct terminology is fire resistance level or FRL. While fire rating plays a part in the various parts of a FRL, the two are not the same or interchangeable. When it comes to a FRL, it is important to … See more The technical expression of an FRL is: Structural adequacy/integrity/insulation or SA/INT/INS 1. Structural adequacyis defined as the measure of a tested assembly to be load … See more The fire testing is conducted by taking a test specimen, representative of what will be used out in the field, and subject it to standard time versus temperature heating conditions and a standard pressure differential. The test … See more AS 1540Part 4 outlines the passing deviations for the three categories and describes how to test each element.
