Measurement of fluid flow by means of pressure differential devices inserted in circular cross-secti...
This document specifies the geometry and method of use (installation and operating conditions) of Venturi tubes[1] when they are inserted in a conduit running full to determine the flow rate of the fluid flowing in the conduit.
This document also provides background information for calculating the flow rate and is applicable in conjunction with the requirements given in ISO 5167-1.

Anaesthetic and respiratory equipment — Tracheobronchial tubes
This document specifies requirements for safety, materials, design and information supplied with tracheobronchial tubes. These devices are used when isolation of the airways of one or both lungs is required.
Tracheal tubes that include bronchus blockers are excluded from the scope of this document
Measurement of gas flow by means of critical flow nozzles
This document specifies the geometry and method of use (installation in a system and operating conditions) of critical flow nozzles (CFNs) used to determine the mass flow rate of a gas flowing through a system basically without the need to calibrate the CFN. It also gives the information necessary for calculating the flow rate and its associated uncertainty.
This document is applicable to nozzles…
