Designation:G21013Standard Practice forOperating the Severe Wastewater Analysis TestingApparatus1This standard is issued under the fixed designation G210;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 covers the basic apparatus,procedures,and conditions required to create and maintain the severewastewater analysis testing apparatus used for testing a pro-tective coating or lining.1.2 This apparatus may simulate the pertinent attributes of atypical domestic severe wastewater headspace(sewer)envi-ronment.The testing chamber comprises two phases:(1)aliquid phase containing a prescribed acid and saline solution,and(2)a vapor phase consisting of air,humidity,and concen-trated sewer gas(Note 1).The temperature of the test chamberis elevated to create accelerated conditions and reaction rates.NOTE1For the purposes of this practice,sewer gas is composed ofhydrogen sulfide,carbon dioxide,and methane gas.1.3 CautionThis practice can be extremely hazardous.All necessary precautions need to be taken when working withsewer gas,sulfuric acid,and a glass tank.It is highlyrecommended that a professional testing laboratory experi-enced in testing with hydrogen sulfide,carbon dioxide,andmethane gases perform this practice.1.4 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 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 and health practices and determine the applica-bility of regulatory limitations prior to use.Some specifichazards statements are given in Section 8 on Hazards.2.Referenced Documents2.1 ASTM Standards:2A36 Specification for Carbon Structural SteelC307 Test Method for Tensile Strength of Chemical-Resistant Mortar,Grouts,and Monolithic SurfacingsC387 Specification for Packaged,Dry,Combined Materialsfor Mortar and ConcreteC580 Test Method for Flexural Strength and Modulus ofElasticity of Chemical-Resistant Mortars,Grouts,Mono-lithic Surfacings,and Polymer ConcretesD610 Practice for Evaluating Degree of Rusting on PaintedSteel SurfacesD638 Test Method for Tensile Properties of PlasticsD660 Test Method for Evaluating Degree of Checking ofExterior PaintsD661 Test Method for Evaluating Degree of Cracking ofExterior PaintsD714 Test Method for Evaluating Degree of Blistering ofPaintsD790 Test Methods for Flexural Properties of Unreinforcedand Reinforced Plastics and Electrical Insulating Materi-alsD2370 Test Method for Tensile Properties of Organic Coat-ingsD4541 Test Method for Pull-Off Strength of Coatings UsingPortable Adhesion TestersD6677 Test Method for Evaluating Adhesion by KnifeD7091 Practice for Nondestructive Measurement of DryFilm Thickness of Nonmagnetic Coatings Applied toFerrous Metals and Nonmagnetic,Nonconductive Coat-ings Applied to Non-Ferrous MetalsG193 Terminology and Acronyms Relating to Corrosion1This practice is under the jurisdiction of ASTM Committee G01 on Corrosionof Metals and is the direct responsibility of Subcommittee G01.05 on LaboratoryCorrosion Tests.Current edition approved Oct.1,2013.Published October 2013.DOI:10.1520/G0210-13.2For 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 2.2 ISO Standards:3ISO 16773 Paints-and Varnishes-Electrochemical Imped-ance Spectroscopy(EIS)on High Impedance CoatedSamples.Part 1:Terms and DefinitionsISO 16773 Paints-and Varnishes-Electrochemical Imped-ance Spectroscopy(EIS)on High Impedance CoatedSamples.Part 2:Collection of DataISO 16773 Paints-and Varnishes-Electrochemical Imped-ance Spectroscopy(EIS)on High Impedance CoatedSamples.Part 3:Processing and Analysis of Data fromDummy Cells3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 domestic wastewater,nwastewater discharged fromresidences and from commercial,institutional,and similarfacilities.3.1.2 sewer headspace,nthe air space between the watersurface and the top of the pipe(crown)or other enclosedstructure.3.2 For definitions of terms used in this practice,seeTerminology G193.4.Summary of Practice4.1 The corrosion protection of steel,ductile iron,andconcrete by a protective coating or lining may be altered byexposure to sewer gases and by the composition of thecorrosive reagents found in headspace environments of domes-tic was
