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.
