Spread of fire ( Flame Retardant) test –BS 61386-1:2008

EMPRO electrical conduits are tested according to the BS EN 61386-1:2008 (13.1.3.2.1) to evaluate

their flame retardant property and confirmed by Sri Lanka Industrial Technology Institute

(Test report No. SS1504413 - copy annexed) that samples tested are resistant to flame propagation

and self extinguishing.
