This results in reduced flame spread
and smoke generation.
Additionally, small-scale test data can be used to estimate material pyrolysis and combustion properties for use as input in models with flame spread
He says that the higher desired density of 20 pcf translated into more fuel in the E84 burn test, creating technical hurdles as far as retarding smoke generation and flame spread
. "But through our extensive technical expertise, we were able to overcome this challenge, resulting in a novel product that has utility beyond its original application." www.bayone.com.
The flame spread
behavior of nylon 6 and nanocomposites as very thin films (~0.5-mm thickness) was investigated using horizontal flame spread
These cables meet stringent NFPA tests for flame spread
and smoke for improved fire safety performance.
Instead of adding chemicals, the fabric is incorporated as an extra layer of protection during the manufacturing process, acting as a shield against flame spread
Best results in pentane-blown foams were obtained with Saytex RB-7001, which gave a flame spread
of 29.4 and smoke density of 415.
Prior to the code approval of the use of low smoke and low flame spread
cable in the return-air-plenum spaces, all cables had to be placed in metal conduit.
The system is composed of Polyvinylidene Fluoride (PVDF) resin, the only plastic piping material that meets the ASTM E-84 25/50 flame spread
and smoke generation building and fire code requirements.
