Published By Publication Date Number of Pages
JIS 2009-09-24 24
]]> This Standard specifies the measurement methods for performance characteristics of turbomolecular pumps.

It is applicable to all types of turbomolecular pumps irrespective of sizes or types.

For example, all turbomolecular pumps are covered regardless of the divisions shown below.

a) mechanical bearing (plain bearing/rolling bearing) and magnetic bearing

b) with or without drag pump stage

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 5302: 2003 Vacuum technology-Turbomolecular pumps-Measurement of performance characteristics (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ lEC Guide 21.

Published By Publication Date Number of Pages
ISO 2009-02 20
]]> ISO/TS 27893:2009 gives guidelines for the determination and reporting of measurement uncertainties arising during vacuum gauge calibration by direct comparison with a reference gauge in accordance with ISO/TS 3567. It describes methods for uniform reporting of uncertainties in vacuum gauge certificates. Uncertainties reported in accordance with ISO/TS 27893:2009 are transferable in the sense that the uncertainty evaluated for one result can be used as a component in the uncertainty evaluation of another measurement or calibration in which the first result is used.

This specification defines two measurement models that are sufficient to cover most practical cases. However, it is possible that the models given cannot be applied to newly developed vacuum gauges.

The final uncertainty to be reported in a certificate is evaluated from the uncertainties of the input quantities and influence quantities. The principal quantities that may affect the result of a vacuum calibration are described; however, a complete list of the possible quantities that may have an influence on the final result lies outside the scope of ISO/TS 27893:2009.
