Designation:E151915bStandard Terminology Relating toAgricultural Tank Mix Adjuvants1This standard is issued under the fixed designation E1519;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 terminology is used or is likely to be used in testmethods,specifications,guides,and practices related to agri-cultural tank mix adjuvants.1.2 These definitions are written to ensure that standardsrelated to agricultural tank mix adjuvants are properly under-stood and interpreted.2.Referenced Documents2.1 ASTM Standards:2D459 Terminology

Compositionof Insulating Oils of Petroleum Origin3.Terminology3.1 Terms and Definitions:absorption,na process in which one material(the absorbent)takes in and retains another(the absorbate).acidifier,na material that can be added to spray mixtures tolower the pH.activator,na material that increases the biological efficacy ofagrichemicals.active ingredient,na component of the formulation thatproduces a specific effect for which the formulation isdesigned.adjuvant,na material added to a tank mix to aid or modifythe action of an agrichemical,or the physical characteristicsof the mixture.alkalinity agent,na material that can be added to the spraymixture to raise the pH.amphoteric surfactant,na surface-active agent capable offorming,in aqueous solution,either surface-active anions orsurface-active cations depending on the pH.anionic surfactant,nsurface-active agent in which thehydrophilic portion of the molecule forms exclusively anegative ion(anion)when placed in aqueous solution.antifoaming agent,na material used to inhibit or prevent theformation of foam.attractant,na material that attracts specific pests.basic blend,na combination of wetting agent and bufferingagent that maintains a pH of the spray mixture greater than7.buffer or buffering agent,na compound or mixture that,when contained in solution,causes the solution to resistchange in pH.Each buffer has a characteristic limited rangeof pH over which it is effective.canopy penetrating agent,nan adjuvant that increases thepenetration of the spray material into the crop canopy.Seedeposition aid.cationic surfactant,na surface-active agent in which thehydrophilic portion of the molecule forms exclusively apositive ion(cation)when placed in aqueous solution.colorant,na material used to alter the color of the tank patibility agent,na surface-active agent that allowssimultaneousapplicationofliquidfertilizerandagrichemical,or two or more agrichemical formulations,asa uniform tank mix,or improves the homogeneity of themixture and the uniformity of the application.crop oil concentrate,nan emulsifiable petroleum oil-basedproduct containing 15 to 20%w w surfactant and a mini-mum of 80%w/w phytobland oil.crop oil(emulsifiable),nan emulsifiable petroleum oil-based product containing up to 5%w w surfactant and theremainder of a phytobland oil.crop oil(non-emulsifiable),nSee phytobland oil.1This terminology is under the jurisdiction of ASTM Committee E35 onPesticides,Antimicrobials,and Alternative Control Agents and is the directresponsibility of Subcommittee E35.22 on
