This Standard defines terms commonly used in the calibration of mass flow controllers (MFC) and mass flow meters (MFM). It is intended to provide for worldwide terminology to be used by manufacturers and users.

This Standard defines terminology related to MFC/MFM calibration. At present, there are often several words used by the semiconductor industry to describe the same concept or device. This Standard is intended to eliminate confusion and provide for a common language which users and manufacturers can employ to discuss MFC/MFM calibration.
