AS 1530: Part 4 | Australia | Fire tests for building parts |
These tests prove panels work well in fires. They also help you follow local and global fire safety laws.
Fire Ratings for Roof Sandwich Panels
Overview of fire ratings (e.g., EW30, EW60, EI15, EI30)
Fire ratings show how well materials handle fire and protect buildings. Ratings like EW30, EW60, EI15, and EI30 tell how long a material lasts in fire. For example, EW30 means it stays strong and blocks heat for 30 minutes. EI ratings add insulation, keeping heat and flames away longer.
Some products, like PYRANOVA®, meet fire classes from EI15 to EI120 and EW30 to EW60. These materials offer great fire safety for buildings and people. They also follow global standards like ISO and EN 13501-2, proving they work well in real fires.
How fire ratings are determined and their implications
Fire ratings come from strict testing. Tests copy fire conditions to check how materials react to heat. Panels are tested to see if they stop fire spread and stay strong.
The table below shows how materials affect fire growth:
Material Type | Fire Behavior Observed | Contribution to Fire Growth |
|---|---|---|
PIR | Makes flammable gases, increasing fire spread | Yes |
Stone Wool | Does not help fire grow | No |
These results prove stone wool works better in fire-rated panels. Picking the right material improves fire safety and meets rules.
