Inert gas must discharge 95% within how many seconds for class B fires?

Discharge time is critical for inert gas extinguishing because the fire-suppressing effect depends on rapidly building up a sufficient gas concentration in an enclosed space. Releasing 95% of the content within 90 seconds ensures the space reaches the necessary concentration quickly enough to knock down a Class B fire and prevent reignition, while still being feasible for the hardware and space sizes typically used. A shorter time would be impractical for larger deployments, and a longer time would risk the fire growing before enough agent is in place. This 95% in 90 seconds standard provides a reliable balance for effective suppression.
