The artificial plant panels we sell are according to the European standard (EN13501-1:2007+A1:2009) classified as fire behaviour class C, which means that they have a limited contribution to a fire.
The test results are as follows:
SGS test report No SHAEC1614728101
Date 22 July 2016
Fire behaviour C
Smoke production s2
Flaming droplets d2
If your risk assessment requires the artificial plant panels to meet a specific fire safety requirement higher than class C you would have to spray them with a fire-retardant treatment spray such as Envirograf 321 Fire Retardant Spray (EV321S Special: Plastic artificial plants / flowers and decorations).
