BS ISO 20146:2019

This standard BS ISO 20146:2019 Vacuum technology. Vacuum gauges. Specifications, calibration and measurement uncertainties for capacitance diaphragm gauges is classified in these ICS categories:

• 23.160 Vacuum technology

This document defines terms related to capacitance diaphragm gauges (CDGs), specifies which parameters have to be given for CDGs, details their calibration procedure and describes which measurement uncertainties have to be considered when operating these gauges.

This document complements ISO 3567 and ISO 27893 when calibrating CDGs and using them as reference standards.
