ISO TS 20175 - Vacuum technology - Vacuum gauges - Characterization of quadrupole mass spectrometers for partial pressure measurement
April 1, 2018 - ISO

This document describes procedures to characterize quadrupole mass spectrometers (QMSs) with an ion source of electron impact ionization and which are designed for the measurement of atomic massto- charge ratios m/z < 300. This document is not applicable to QMSs with other ion sources, such as...

TAPPI TIP 0402-21 - Ultrasonic technician performance test for boiler tube thickness measurement
January 1, 2018 - TAPPI

This procedure has been developed by a TAPPI Task Group to offer a basis for evaluating the skills of technicians who measure the thickness of boiler tubes from the external surface using manual instruments. Use of this procedure is prudent when surveying the thickness of recovery boiler tubes,...

BS 5914 - Methods of Calibrating Leak-Detectors of the Mass-Spectrometer Type Used in the Field of Vacuum Technology
March 31, 1980 - BSI

Specifies procedures for determining a sensitivity figure for mass-spectrometer type leak detectors. Two procedures are outlined, one for determining minimum detectable leak rate; the other for determining minimum detectable concentration ratio. Specifically excepted are sensing...
