Non Combustible/ Limited Combustible

So would you accept Flame Stop to meet either of those terms??
No. All it does is improve the flame spread characteristics of the material. It doesn't make the material fire-resistant or noncombustible.
Anyone approve or use Flame stop to meet NFPA 13 for noncombustible or limited combustible?
It would be considered a "limited-combustible material" by NFPA definition since the flame spread would be 25 or less and probably doesn't evidence progressive combustion after the coating is applied.

if field applied, would you just do a field test ???


Or would you let it be field applied??

Plus this statement from the manufacture::::




. It does contain polymers that maintain the fire retardation for up to five years for exterior applications and reapplication is recommended every five years
 
Assuming they have a testing laboratory report that indicates the product meets a Class A finish (flame spread of 25 or less) and the sample was based on the product applied per manufacturer's instructions, then, if installed in accordance with the manufacturer's instructions in the field, it should be acceptable there. However, if the product has limited performance over time for exterior applications, I would not suggest that it be used where a limited-combustible material is required in an exterior application since there is no continued protection after five years and there is no guarantee that reapplication will occur as recommended.

Thanks trying to get arguments lined up, when hit with, ¿ why not?

Been in this to long and down to just a few to bounce code questions off of.
