YY/T 1743-2021 Anaesthetic and respiratory equipment—Nebulizing systems and components
Basic Information
Scope
This standard specifies the requirements for safety and performance testing of general atomization systems that are intended to deliver liquids to the human body continuously or upon respiratory triggering in the form of a spray through the respiratory system.
This standard applies to pneumatic atomization devices, which can be powered by compressors, piping systems, cylinders, etc., as well as electric atomization devices [such as rotating discs, ultrasound, vibrating screens (active and passive), and capillary devices] or manual atomization devices.
This standard does not specify the minimum performance of atomization systems.
This standard does not apply to nasal irrigation devices.
This standard does not apply to devices intended solely for providing humidity or hydration by supplying water in the form of aerosol particles.
Note: Such devices are referred to in ISO 8185 [3].
This standard does not apply to specific drug delivery atomization devices or their components (such as metered dose inhalers, metered liquid inhalers, and dry powder inhalers).
