ICH stability zones (IVb hot-humid)

TL;DR

ICH stability zones translate global climate into testing conditions: Zone I 21°C/45% RH, Zone II 25°C/60% RH (US/EU baseline), Zone III 30°C/35% RH (hot-dry), Zone IVa 30°C/65% RH and Zone IVb 30°C/75% RH (hot-very-humid: ASEAN, Brazil, Caribbean). A supplement programme inte...

ICH stability zones translate global climate into testing conditions: Zone I 21°C/45% RH, Zone II 25°C/60% RH (US/EU baseline), Zone III 30°C/35% RH (hot-dry), Zone IVa 30°C/65% RH and Zone IVb 30°C/75% RH (hot-very-humid: ASEAN, Brazil, Caribbean). A supplement programme intended for ASEAN or LATAM distribution runs Zone IVb long-term in addition to Zone II — and bracketing/matrixing per ICH Q1D cuts the cost.

How V5 handles it
QMS — quality engineered into every action, not bolted on.
Because V5 owns the operator action, the QMS sees the data the second it’s captured — not at the end of the shift.
Document control with hard kiosk-level training enforcement.
Versioned SOPs are only useful if operators are actually trained on the current version. V5 enforces it at the kiosk.
