Designation:D523219Standard Practice forDetermining the Stability and Miscibility of a Solid,Semi-Solid,or Liquid Waste Material1This standard is issued under the fixed designation D5232;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 practice is designed to determine whether a wastematerial reacts when it is mixed with air,water,strong acid,strong base,an oil/solvent mixture,other waste mixtures,orsolid media such as a geological formation or solidificationagents.1.2 The miscibility of the waste material with the abovemedia can also be defined.NOTE1The following ASTM standards provide supplemental infor-mation:Test Methods D4978,D4980,D4982,D5049,and D5057 andPractices D4979,D4981,and D5058.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 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.For specific hazard statements,see Section 8.1.5 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:2D1193 Specification for Reagent WaterD4978 Test Methods for Screening of Reactive Sulfides inWasteD4979 Practice for Physical Description Screening Analysisin WasteD4980 Test Methods for Screening of pH in Waste(With-drawn 2009)3D4981 Practice for Screening of Oxidizers in WasteD4982 Test Methods for Flammability Potential ScreeningAnalysis of WasteD5049 Test Method for Screening Cyanides In Waste(With-drawn 1999)3D5057 Test Method for ScreeningApparent Specific Gravityand Bulk Density of WasteD5058 Practices for Compatibility of Screening Analysis ofWasteD5681 Terminology for Waste and Waste Management3.Terminology3.1 Definitions of terms in this practice appear in Terminol-ogy D5681.4.Summary of Practice4.1 The stability and miscibility of a waste material areobserved when the waste is mixed with various media.5.Significance and Use5.1 This practice will identify waste materials that arepotentially unstable when they come in contact with othermaterials at a waste treatment or disposal site.5.2 This practice will serve to determine the miscibility ofwaste materials with various media,including other wastes.5.3 This practice may not be applicable to all wastes.Theappropriateness of these tests depends upon the proposedmanagement of the waste.5.4 Since the initiation of some chemical reactions are slowto take place,the user may wish to establish reagent-to-wastecontact times prior to observing the mixes for any reactions.6.Apparatus and Materials6.1 Disposable Cups,minimum 40-mL total volume.Selectplastics or other materials compatible with the reagents in-volved.1This practice is under the jurisdiction of ASTM Committee D34 on WasteManagement and is the direct responsibility of Subcommittee D34.01.06 onAnalytical Methods.Current edition approved Sept.1,2019.Published September 2019.Originallyapproved in 1992.Last previous edition approved in 2013 as D5232 13.DOI:10.1520/D5232-19.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.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 6.2 Stirring Rods,Spatulas,Disposal Droppers,WatchGlasses,and so forth.6.3 Other waste materials to be evaluated with the testsample.6.4 Solid Media,to be evaluated with the test sample.7.Reagents7.1 Purity of WaterThe deionized water used to preparethe aqueous test solutions should conform to the conductivityspecifications ofASTM Type II water as found in SpecificationD1193.7.2 Hydrochloric Acid(HCl)Test SolutionCarefully mix100 g of reagent-grade hydrochloric acid(;36%)with 900 gof deionized water.7.3 Sodium Hydroxide(NaOH)Test SolutionCarefullymix 2
