scope:

This International Standard specifies general requirements for laryngoscopes used for intubation and
critical dimensions for the handle and lamp of hook-on type laryngoscopes. It also addresses the
interchangeability of blades and handles.
It is applicable only to instruments with an internal battery-operated power source for illuminating the
larynx, since electrical safety requirements may be more stringent for instruments connected to mains
or external power packs.
This International Standard is not applicable to surgical instruments known by the same generic name.
This International Standard does not apply to:
- flexible laryngoscopes, or laryngoscopes designed for surgery;
- laryngoscopes powered from mains electricity supply;
- laryngoscopes connected by light-transmitting cables to external light sources.
NOTE Instruments connected by light guides to an external light source may be subject to other International Standards for endoscopes.
