Standard Specification for Modular Gauge Boards
|Publication Date:||1 August 2019|
|ICS Code (Navigation and control equipment):||47.020.70|
1.1 This specification covers modular gauge boards for mounting 89-mm [31/2-in.], 114-mm [41/2-in.], 152-mm [6-in.], and 216-mm [81/2-in.] dial size pressure gauges and dial thermometers for miscellaneous shipboard applications.
1.2 Gauge boards ordered under this specification are suitable for pressure gauges and dial thermometers with either turret or back flanged type cases and with either back or bottom connections (see Appendix X1).
1.3 Gauge mounting dimensions shall be in accordance with ASME B40.1.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
Note 1: Gauge boards covered by this specification are those normally supplied by the shipyard as opposed to the shipyard's equipment subcontractor.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers modular gage boards for mounting dial pressure gages and dial thermometers for miscellaneous shipboard applications. Gage boards under this specification are suitable for pressure gages and dial thermometers with either turret or back flanged type cases and with either back or bottom connections. Gage boards may be furnished in two types and grades, namely: Type I, Type II, Grade a, and Grade b. Unless otherwise specified the gage boards shall be manufactured from the specified carbon steel for Grade a and form the specified aluminum alloy for Grade b. Materials shall be capable of being bent at room temperature through the prescribed angle and direction without cracking on the outside of the bent portion. Unless otherwise specified, gage boards shall be drilled for mounting the specified dial sizes. When specified, drilling shall be limited to one size gage for either Type I or Type II gage boards. The dimensional requirements for the gage boards are detailed and illustrated.View Less
