Abstract

Specifies requirements for gauges within the pressure range -100 kPa to +100 000 kPa, and the nominal size range 50 mm to 300 mm. Compound gauges (pressure and vacuum) are also included. Two accuracy grades are specified, namely test gauges and industrial gauges. The gauges are normally graduated directly in kilopascals, but scale factors of powers to ten may be used where required for scale clarity or specified by the purchaser. Other units of pressure may be specified by the purchaser for special applications. The gauges are generally suitable for use with common fluids such as air, oil, water, or steam, but special provision is made for high pressure gauges, and gauges which are intended for use with oxygen and acetylene, or other reactive gases. Appendices provide notes of correction of deadweight testers and manometers, recommendations for the installation and use of gauges, and purchasing guidelines.
RECONFIRMATION NOTICE
Major stakeholders of this publication have reviewed the content of this publication and in accordance with Standards Australia procedures for reconfirmation, it has been determined that the publication is still valid and does not require change.
Certain documents referenced in the publication may have been amended since the original date of publication. Users are advised to ensure that they are using the latest versions of such documents as appropriate, unless advised otherwise in this Reconfirmation Notice.
Approved for reconfirmation in accordance with Standards Australia procedures for reconfirmation on 29 August 2018.

Scope

This standard specifies requirements for Bourdon tube pressure and vacuum gauges with circular concentric scales within the pressure range - 100 kPa to + 100 000 kPa, and the nominal size range (approximate dial diameter) 50 mm to 300 mm. Compound gauges (pressure and vacuum) are also included.

The gauges are graded according to accuracy, two grades being specified, viz test gauges and industrial gauges. The gauges are generally suitable for use with fluids such as air, oil, water or steam, but special provision is made for gauges which are intended for high pressure applications, or for use with oxygen or acetylene, or with other reactive gases.

NOTES:
1. Recommendations regarding the installation and use of pressure gauges are given in Appendix B.
2. Guidelines for purchasers on specifying requirements when ordering gauges are given in Appendix C.
