Designation:F1460/F1460M18Standard Practice forCalibrating Oil Spill Dispersant Application EquipmentBoom and Nozzle Systems1This standard is issued under the fixed designation F1460/F1460M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers uniform procedures for determiningand reporting the dosage rate of oil spill dispersant applicationequipment.1.2 This practice is applicable to spray systems employingbooms and nozzles and is not fully applicable to other systemssuch as fire monitors,sonic distributors,or fan-spray guns.1.3 This practice is applicable to systems for use on ships,boats,helicopters,or airplanes.1.4 This practice is one of four related to dispersant appli-cation systems using booms and nozzles.One is on design,oneon calibration,one on deposition,and one on the use of thesystems.Familiarity with all four standards is recommended.1.5 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.7 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 ASTM Standards:2F1413 Guide for Oil Spill Dispersant Application Equip-ment:Boom and Nozzle Systems3.Significance and Use3.1 This practice will enable calibration of oil spill disper-sant application equipment and ensure a desired dosage anduniformity across the swath width.3.2 The data provided by the methods described herein willpermit the preparation of a chart relating delivery rate withapplication vehicle speed,flow meter reading or pump settingso that in actual application,the desired dosage will beachieved.3.3 This practice will ensure that a dispersant applicationsystem is functional,capable of delivering a specified dosage,and that major components are operational.This will alsoensure that the unit is functioning according to design specifi-cations as detailed in Guide F1413.4.Apparatus and Materials4.1 Pailsof capacity 7 to 20 L2 to 5 U.S.gal to catch thespray from the nozzles.4.2 Graduated Cylinderof capacity 7 to 20 L 2 to 5 U.S.gal or a scale having capacity of at least 20 kg 45 lbs todetermine the amount of fluid in each pail.Commercialequipment with an accuracy of at least 1%is adequate.4.3 Stopwatch.4.4 Test FluidWater can be used as a test fluid if theviscosity of the dispersant to be used is not dissimilar to theviscosity of water.A test fluid should be used if the viscositydifference is greater than approximately 100 times that of1This practice is under the jurisdiction of ASTM Committee F20 on HazardousSubstances and Oil Spill Response and is the direct responsibility of SubcommitteeF20.13 on Treatment.Current edition approved Oct.1,2018.Published December 2018.Originallyapproved in 1993.Last previous edition approved in 2013 as F1460 07(2013).DOI:10.1520/F1460-18.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.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 water.This can occur with more viscous dispersants or at lowtemperatures.The test fluid could be water with the appropriateamount of thickener.4.5 Acontinuing supply of water or test fluid,enough to runthe system during the test period,must be available.Tank truckquantities may be required.4.6 Auxiliary Power Units,where required.4.7 Thermometer,to measure the temperature of test fluid.4.8 FlowmeterA flowmeter should be incorporated intothe delivery system to measure the total flow out to the boomsand nozzles.5.Calibration Procedure5.1 Syno
