Designation:D 3263 03An American National StandardStandard Test Methods forCorrosivity of Solvent Systems for Removing Water-FormedDeposits1This standard is issued under the fixed designation D 3263;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(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods cover the determination of corrosiv-ity of solvent systems used to remove water-formed depositsfrom the metal and alloy surfaces of water handling equipment.Four test methods are given as follows:SectionsTest Method ACorrosivity in the Absence of Deposits10 to 15Test Method BCorrosivity in the Presence of Selected Ions16 to 21Test Method CCorrosivity with Magnetite-Coated SteelSpecimens22 to 28Test Method DCorrosivity with Deposit-Coated Specimens29 to 351.2 Test Methods A and B provide for corrosivity testingunder either static immersion or dynamic conditions.1.3 Test Methods C and D are procedures applicable forcorrosivity testing under static immersion conditions only.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:D 1129 Terminology Relating to Water2D 1193 Specification for Reagent Water2D 2790 Test Methods of Analysis of Solvent Systems Usedfor Removal of Water-Formed Deposits33.Terminology3.1 Definitions:3.1.1 For definitions of terms used in these test methods,refer to Definitions D 1129.3.2 Definitions of Terms Specific to This Standard:3.2.1 solvent systemspecified chemicals or combinationsof chemicals,which may include corrosion inhibitors designedto react with and remove deposits.4.Summary of Test Methods4.1 These test methods consist of procedures wherein thecorrosivity of solvent systems is determined by the weight lossexperienced by metal specimens during exposure to the solventsystems.4.2 Test Method A is a procedure to determine corrosivityfrom the weight loss of metal specimens during exposure tosolvent systems in the absence of deposits.This corrosivity canbe determined by either static immersion or dynamic tech-niques.4.3 Test Method B provides the determination in solventsystems that have had selected ions added.It describes tech-niques for manufacturing the solvent with the desired ions andrefers to Test Method A for the acutal corrosivity testing.4.4 Test Method C describes the techniques used to producemagnetited specimens that are subsequently used for thedetermination of the corrosivity of the solvent system.4.5 Test Method D describes the techniques used to producespecimens coated with a synthetic deposit that are subsequentlyused for the determination of the corrosivity of the solventsystem.5.Significance and Use5.1 Test Method A is necessary because the corrosivity of asolvent system can be detrimental to the equipment beingcleaned.It is used to compare the corrosivity of various solventsystems and to determine the corrosivity of selected solventsystems under different conditions.5.2 Test Method B is necessary because the corrosivity of asolvent system can be changed by the presence of ions in thesolvent system.It is used to determine if the ions that might bepresent during a cleaning operation would significantly changethe corrosivity of a solvent system.5.3 Test Method C is necessary because the corrosivity of asolvent system under magnetite removal conditions can bedifferent from the corrosivity in the absence of deposit.It isused to determine the corrosivity of the solvent system undermagnetite removal conditions.5.4 Test Method D is necessary because the presence orabsence of deposits may affect the corrosivity of the solventsystem.It is used to determine the corrosivity of solvent1These test methods are under the jurisdiction of ASTM Committee D19 onWater and are the direct responsibility of Subcommittee D19.03 on Sampling ofWater and Water-Formed Deposits,Analysis of Water for Power Generation andProcess Use,On-Line Water Analysis,and Surveillance of Water.Current edition approved Aug.10,2003.Published September 2003.Originallyapproved in 1973.Last previous edition approved in 1999 as D 3263 82(1999)e1.2Annual Book of ASTM Standards,Vol 11.01.3Discontinued.See 1992 Annual Book of ASTM Standards,Vol 11.02.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.systems on deposit-coated specimens.These results are com-pared with results obtained from Test Method A to determinethe effect of the deposit.6.Specimen Composition and Size6.1 Test specimens for Test MethodsA,B,and C may be flatcoupons,either rectangular or circular in shape,or r
