Designation:E110291(Reapproved 2015)Standard Terminology Relating toAgricultural Chemical Application1This standard is issued under the fixed designation E1102;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 The purpose of this terminology standard is to establishuniformity in terms used in the field of agricultural chemicalapplication.Terms are adopted from related fields and whereapplicable from Terminology E609.1.2 The terms are appropriate to any agricultural chemicalapplication.Units in parenthesis following a definition aremeant as typical and are not exhaustive of all units available forthe term.2.Referenced Documents2.1 ASTM Standards:2E609 Terminology Relating to Pesticides3.TerminologyGENERAL CHEMICAL TERMS ANDCHARACTERISTIC MEASUREMENTSair flow ratethe flow rate of air,expressed in volume perrelevant unit(ft3/min,m3/s,m3/tree).application ratethe amount of any material applied per unittreated:active chemical ratethe amount of active ingredient(a.i.)applied per unit treated,expressed in terms of mass perrelevant unit treated.(For area treatment,kg a.i./ha,lb a.i./A,or oz a.i./1000 ft.of row;for space application,mg a.i./m3,or oz a.i./1000 ft3;for individual units,kg a.i./plant oranimal).formulation ratethe amount of chemical formulation appliedper unit treated,expressed in terms of mass or volume perrelevant unit treated.(For area treatment,kg/ha,lb/A,oroz/1000 ft of row;for space application,mg/m3,or oz/1000ft3;for individual units,kg/plant or animal).spray ratethe amount of spray liquid emitted by an applica-tion unit during treatment,expressed in volume per unittreated.(For area treatment,L/ha,or gal/A;for spacetreatment,mL/m3,or oz/1000 ft3;for individual units,L/plant,mL/animal,or gal/tree).concentrationamount of the active ingredient contained inthe chemical formulation expressed as a percent or mass perrelevant unit basis.cumulative droplet diameter(Dv.1andDv.9)diameter ofdrop such that 10%and 90%,respectively,of the liquidvolume is in drops of smaller diameter.deposit ratethe amount of any material deposited per unitarea.active chemical deposit ratethe amount of active ingredientdeposited per unit area.formulation deposit ratethe amount of formulation depositedper unit area.spray deposit ratethe amount of spray liquid deposited perunit area.Mean deposit rate is the average amount of depositover the entire spray swath.Effective spray deposit rate isthe mean deposit from center to center of adjoining swaths.diluenta gas,liquid,or solid used to reduce the concentra-tion of an active ingredient in the formulation or applicationof a pesticide(see Terminology E609).driftthe movement of chemicals outside the intended targetby air mass transport or diffusion.airborne driftthe dispersion of chemical particles to theatmosphere outside the intended target.particle drift depositsthe deposition of chemical particlesoutside the intended target.vapor driftthe dispersion of vaporized chemical to theatmosphere and areas surrounding the target area during andfollowing application.formulationthe form in which a chemical is offered to theuser.1These terminologies are under the jurisdiction of ASTM Committee E35 onPesticides,Antimicrobials,and Alternative Control Agents and is the directresponsibility of Subcommittee E35.22 on Pesticide Formulations and DeliverySystems.Current edition approved Oct.1,2015.Published November 2015.Originallyapproved in 1986.Last previous edition approved in 2009 as E1102 91(2009).DOI:10.1520/E1102-91R15.2For 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 States1 mean droplet diameter(Dpq)is represented by the follow-ing:Dpqp2q!5(Dip(Diq(1)where:Di=the diameter of the ithparticle,Dio=the total number of drops in the sample.Thus:D10=length mean diameter,D20=area mean diameter,D30=volume mean diameter,D31=volume/length mean diameter(mean evaporativediameter),D32=SAUTER mean diameter,andD43=DeBROUKERE or HERDAN mean diameter.median droplet diameter(Dxf)For cumulative distributions,Dxf,where x is V,A,L,or N,are diameters such that thefraction(f)of the total of volume,surface area,length ofdiameter,or number of drops respectively,is in drops ofsmaller diameter.Thus:DV.5=volume median diameter,DA.5=area median diameter,DL.5=length median diameter,andDN.5=number median diameter.Also,DV.1and DV.9=diameter of drop such that 10%and90%respectively,of the liquid volume is in drops of smallerdiameter.percent nozzle pattern overlapcalculated by subtractingthe nozzl
