Pvc Roof Flame Test

Pvc roofing membranes have passed fm and ul fire testing and have an unlimited slope approval.

Pvc roof flame test.

While it is true that tpo and pvc are both single ply membranes for low slope and flat. Pvc roof membranes are inherently flame resistant but as discussed above that s only one part of the equation. If no flame is produced quickly hold the sample in the flame for about 10 seconds. In recent years tpo roofing has been steadily gaining its share in the flat roofing market.

Vertical strip fire test another test method to show how different roof membranes perform when exposed to fire is a vertical strip fire test. The pvc roof cover has almost 60 percent better spread of flame resistance than the other membranes. Ib pvc roofing membranes have passed stringent fire testing standards at both ul and fm and are approved for use in low steep and unlimited slope assemblies. The test compares the behavior of three common commercial single ply roofing materials vinyl or pvc tpo and epdm after they are ignited by a bunsen burner flame.

Both commercial and residential customers are increasingly choosing tpo roofs because they are advertised as being similar to pvc in terms of the benefits and installation but offering a more competitive price. In this electrical circuit the membrane acts as an isolator between the positively charged electrical plate on the membrane surface and the conductive deck which is considered the ground. In the test the vinyl roofing sample self extinguishes in seconds 13 in one 12 in the other after the flame source is removed while the other two samples continue to burn for between 3 and 6 minutes apiece before they are completely consumed. Pvc roofing membranes have a solid fire resistance rating.

Next hold the sample to the edge of a flame until it ignites. These roofs are difficult to ignite burn slowly do not support combustion and self extinguish when the source of flame is removed. Pvc roofs are also extremely durable long lasting and have high reflectivity which can save money on your energy costs. The entire roof area is then wetted with water which creates an electrical plate at the entire top side of the membrane when charged by the test unit.

If the material burns note the color of the flame the nature of the smoke the presence of soot in the air and whether while burning the sample drips. For plastic pellets or small flakes you can bring along a small metal clip to hold the plastic sample. Step one of the plastic burn test is to find a suitable piece of plastic. You want something that is relatively large at least the size of a quarter so your fingers can hold on to it while it burns.
