This document specifies requirements for oropharyngeal airways.

This document is not applicable to metal oropharyngeal airways, nor to requirements concerning flammability of oropharyngeal airways.

This document is not applicable to supralaryngeal airways, which are covered by ISO 11712[1].

The requirements that are also applicable to other airway devices have been removed from this document as they now appear in the general airway device standard (ISO 18190).

The requirements in this device-specific standard take precedence over any conflicting requirements in the general standard for airway devices (ISO 18190).
