ISO 19685:2017 Vacuum technology - Vacuum gauges - Specifications, calibration and measurement uncertainties for Pirani gauges
standard by International Organization for Standardization, 09/01/2017
More info
Full Description
ISO 19685:2017 identifies parameters of Pirani gauges, their calibration procedure, and describes measurement uncertainties to be considered when operating these gauges.
ISO 19685:2017 applies to Pirani vacuum gauges operating over a pressure range of 0,01 Pa to 150 kPa.
ISO 19685:2017 complements ISO 3567 and ISO 27893 when calibrating Pirani gauges and using them as reference standards.
In addition, ISO 19685:2017 defines procedures to characterize Pirani gauges for response time and hysteresis.
