1.1 This specification covers the requirements for electrical liquid level indicating equipment for shipboard low pressure and high pressure tanks containing freshwater, feed water, potable water, seawater, wastewater, diesel fuel, lubricating oil, contaminated oil, refrigerants, JP fuels, and various other fluids. Application includes compensating tanks in which the equipment must locate the interface. 1.2 Each liquid level indicating equipment typically consists of the following components: (a) One or more sensing devices; (b) Flexible interconnections, if needed; (c) Primary indicator panel assembly; (d) Auxiliary indicator panel assembly, when required; and (e) Portable indicator panel assembly, when required. 1.3 Special requirements for naval shipboard applications are included in the Supplementary Requirements section to this specification. 1.4 The values stated in SI units are to be regarded as standard. Inch-pound units are provided for information only and are not considered standard. Where information is to be specified, it shall be stated in SI units. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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.
