Class A Standard (Solid fires, e.g.
paper, wood, plastics)
6.3% Design concentration includes 30%
safety factor
587Bb/01
Class A Cables (Solid fire risks
including cables)
6.1% Confirmation that minimum safety
factor is adequate
Class B (Liquid fires e.g. heptane) 6.4% Design concentration includes 30%
safety factor
Design concentration Class A Standard and Class B = Extinguishing concentration x safety factor (minimum 1.3).
Design concentration Class A Cables System test concentration. Where this value is lower than the Class A Standard value, the
Class A Standard value should be used for design purposes.
Design concentrations are as tested to LPS 1230 in BRE Test Report Number 208832 v2.
Extinguishing concentrations are as tested in BRE Test Report Number 208831 (ISO 14520-1 tests)
This system uses:
