Richard is absolutely correct. It's like trying to compare a match stick to a bon fire.
Regards, Peter L. Tarver, PE [email protected] -----Original Message----- From: [email protected] I just went through this myself. There is no real correlation between UL94 flame ratings and flame spread ratings. The test methods are completely different and one cannot predict the flame spread rating from the flame rating. Richard Woods ---------- From: james Yoo Dear every one I have question about UL 723 Tests for surface burning characteristics of building material. What is the satisfaction flammable grade according to UL94 or UL746 If the FSI(flame spread index) is below 200. If anyone knows about that please let me know.
