ASTM E108
Roof covering materials used for residential and commercial purposes undergo a standard fire resistance testing process to ensure their safety in the event of an emergency. We conduct ASTM 108 tests for these materials and assign a classification depending on their response to a simulated combustion scenario.
What Is ASTM E108?
These standardized testing methods for roof coverings determine the safety and reliability of the materials used in the event of a fire. Materials labeled non-combustible undergo this test procedure that simulates a fire controlled by certain wind conditions.
We then classify the roofing materials into three categories that inform builders of the materials’ response to the severity of the testing conditions. Materials are either:
- Class A: Roof coverings that can withstand extreme fire and wind conditions without failing or collapsing.
- Class B: Roof coverings that can withstand moderate fire and wind conditions.
- Class C: Roof coverings can withstand light fire and wind conditions.
While the testing procedure is straightforward, it requires certain apparatus and testing conditions to maintain a standard reproducible environment where materials have a chance to test thoroughly. Each classification has differing test conditions and parameters to determine success or failure based on its own unique criteria.
Fire Test Methods for Roof Coverings
The procedures involved in the ASTM E108 testing method are conducted in a controlled environment in accordance with building regulations and codes. The procedure is carried out as follows:
- First, we set up the apparatus required to begin testing. Each roof is tested on a slope that can be adjusted to respond to a particular situation. The standard dimensions of this slope are five inches by 12 inches.
- Next, the roofing material is placed on this slope and, depending on the classification being tested, is exposed to a particular flame. The fire is produced by a gas burner and an inline blower while a simulated 12-mph wind blows on the flame to spread it over the material.
- We let the fire burn for a particular amount of time, based on the classification severity. We'll qualify a pass if the material successfully withstands the blaze after the time has elapsed or consider it failed if it collapses.
- We also test different kinds of burning including intermittent, flame spread and flying brand flames.
