This document specifies requirements for anaesthetic reservoir bags for use with anaesthetic and ventilator breathing systems. It includes requirements for the design of the neck, size designation and elasticity.

This document is not applicable to special-purpose bags, for example bellows, self-inflating bags and bags for use with anaesthetic gas scavenging systems.

The requirements in this device-specific standard take precedence over any conflicting requirements in the general standard for airway devices (ISO 18190). All the common requirements that appear in the general standard for airway devices have been removed from this document.
