Designation:F150799(Reapproved 2017)An American National StandardStandard Specification forSurge Suppressors for Shipboard Use1This standard is issued under the fixed designation F1507;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification establishes performance requirementsof surge suppressors for use on shipboard ac power circuits.1.2 Surge suppressor shall be a protective device for limit-ing voltage transients on equipment by discharging,dissipatinginternally,bypassing surge current,or a combination thereofand which prevents continued flow of follow current to groundand is capable of repeating these functions.1.3 Surge suppressors covered by this specification mayconsist of a single circuit element or may be a hybrid deviceusing several suppression devices.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 The following documents of the issue in effect on thedate of material purchase form a part of this specification to theextent referenced herein.2.2 American National Standards:2ANSI/IEEE Std 4 IEEE Standard Techniques for HighVoltage TestingANSI/IEEE C62.41 Recommended Practice on Surge Volt-age in Low-Voltage AC Power CircuitsANSI/IEEE C62.45 Guide on Surge Testing for EquipmentConnected to Low-Voltage AC Power CircuitsANSI/IEEEC84.1 ElectricalPowerSystemsandEquipmentVoltage Ratings2.3 Military Standard:3MIL-STD-1399 Section 300;Military Standard InterfaceStandard for Shipboard Systems,Section 300,ElectricPower,Alternating Current2.4 Underwriters Laboratories Standard:4UL 1449 Transient Voltage Surge Suppressors,2nd Edition3.Terminology3.1 Definitions:NOTE1These definitions other than specific to the standard are takenfrom UL 1449,ANSI/IEEE C62.41,and MIL-STD 1399 to provide forharmonization of terms.3.1.1 combination wave,na surge delivered by an instru-ment that has the inherent capability of applying a 1.2/50-svoltage wave across an open circuit and delivering an 8/20-scurrent wave into a short circuit.The exact wave that isdelivered is determined by the instantaneous impedance towhich the combination wave is applied.(Also called combi-nation voltage/current surge or combination V/I surge.)3.1.2 crest(peak)value(of a wave,surge or impulse),nthe maximum value that a wave,surge,or impulse attains.3.1.3 electric power source,nthe electric power that issupplied for testing.3.1.4 electric power system ground,nground is a plane orsurface used by the electric power system as a commonreference to establish zero potential.Usually,this surface is themetallic hull of the ship.On a nonmetallic hull ship,a specialground system is installed for this purpose.3.1.5 follow(power)current,nthe current from the con-nected power source that flows through a surge protectivedevice following the passage of discharge current.3.1.6 frequency tolerance,nfrequency tolerance is themaximum permitted departure from nominal frequency duringnormal operation,excluding transient and cyclic frequencyvariations.This includes variations such as those caused byload changes,switchboard frequency meter error,and drift.Unless specified otherwise,frequency tolerance shall be con-sidered to be 610%of nominal frequency.1This specification is under the jurisdiction of ASTM Committee F25 on Shipsand Marine Technology and is the direct responsibility of Subcommittee F25.10 onElectrical.Current edition approved Aug.1,2017.Published August 2017.Originallyapproved in 1994.Last previous edition approved in 2011 as F1507 99(2011).DOI:10.1520/F1507-99R17.2Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.3Available from DLA Document Services,Building 4/D,700 Robbins Ave.,Philadelphia,PA 19111-5094,http:/quicksearch.dla.mil.4Available from Underwriters Laboratories(UL),2600 N.W.Lake Rd.,Camas,WA 98607-8542,http:/.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.1.7 inrush current,nthe inrush current is a suddenchange in line current that occurs during startup or as a resultof a change to the operating mode.Inrush current is dependenton the type of load connect
