Fire tests should be conducted with the ignition centred
under one, between two and below four nozzles. Each fire should be
ignited using two igniters as described in 5.5. The igniters should
be placed on the floor, each against the base of one of the two central
stacks and ignited simultaneously. The fire tests should be conducted
for 10 min after the activation of the first nozzle, and any remaining
fire should be extinguished manually.
When positioned between two nozzles, the gap between the
two centric stacks of commodities should be positioned at 90°
to the line between the nozzles.
