*This document specifies requirements for the safety and performance testing of general-purposenebulizing systems intended for continuous or breath-actuated delivery of liquids, in aerosol form, tohumans through the respiratory system.This document includes gas-powered nebulizers which can be powered by, e.g., compressors, pipelinesystems, cylinders, etc., and electrically powered nebulizers [e.g., spinning disc, ultrasonic, vibratingmesh (active and passive), and capillary devices] or manually powered nebulizers.This document does not specify the minimum performance of nebulizing systems.*This document does not apply to:a) devices intended for nasal deposition;b) devices intended solely to provide humidification or hydration by providing water in aerosol form.NOTE ISO 80601-2-74 [3] and ISO 20789[[4]] cover these devices.*This document does not apply to drug-specific nebulizers or their components (e.g., metered doseinhalers, metered liquid inhalers, dry powder inhalers).
