Designation:D128014Standard Guide forTotal Immersion Corrosion Test for Soak Tank MetalCleaners1This standard is issued under the fixed designation D1280;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 guide covers determination of the corrosive effectsof soak tank metal cleaners on all metals other than aluminumand its alloys,under conditions of total immersion,by quanti-tative measurement of weight change or by qualitative visualdetermination of change.The test determines the effects of thecleaner on metals being cleaned,and does not determine thelife of the cleaner or of the containing equipment.1.2 When the test is used to assist in the choice of materialfor a specific use,the test conditions should simulate theconditions of use as closely as practicable.1.3 Where no further processing subsequent to cleaning isindicated,a test for the effect of residual cleaner on thecorrosion behavior of the material may be required.1.4 The values stated in SI units are to be regarded asstandard.The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and 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.Material SafetyData Sheets are available for reagents and materials.Reviewthem for hazards prior to usage.2.Referenced Documents2.1 ASTM Standards:2D930 Test Method of Total Immersion Corrosion Test ofWater-Soluble Aluminum Cleaners(Withdrawn 2001)33.Significance and Use3.1 This guide is used to distinguish soak tank metalcleaners that are excessively corrosive to metals(other thanaluminum and its alloys which are covered by Method D930).The users will define the degree of corrosion consideredexcessive,in terms of weight loss per unit of surface area or interms of changes in appearance,or both.4.Apparatus4.1 Test Tubes,of a suitable material 38 mm in diameter by300 mm in length,having a capacity of about 300 mL.Thetubes shall be chosen so that the specimens will remain fullyimmersed during the test,and the ratio of area of immersedmetal to the volume of solution will be prescribed in 7.1,withsufficient space provided for foam formation.4.2 Condensers,Allihn-type,having jackets 200 to 250 mmin length,except that condensers will not be required for testsrun at room temperature.4.3 Stoppers or JointsThe connection between test tubeand condenser optionally may be either standard-taper joints orrubber stoppers preboiled in aqueous caustic soda to removefree sulfur,and boiled in a sufficient number of changes ofdistilled water until neutral.4.4 Constant-Temperature DeviceAny suitable meansmay be employed for maintaining the solutions actively at theboiling point for tests conducted at that temperature.For testsmade at other temperatures,a suitable constant-temperaturebath shall be provided to maintain the required temperaturewithin 1C(62F).For control testing at room temperature,itis suggested that the solution be maintained at 35 6 1C(95 62F),which,being slightly above most room temperatures,iseasy to maintain by heat input.4.5 Coating Apparatus,shall be provided suitable for pro-ducing a uniform film of cleaner on the surface of the testspecimen,for testing the effects of residual cleaner on thesurfaces of cleaned metals(Section 10).4.6 Humidity Chamber,for exposing the contaminatedspecimens at 90%relative humidity as specified in 10.1.3.1This guide is under the jurisdiction of ASTM Committee D12 on Soaps andOther Detergents and is the direct responsibility of Subcommittee D12.16 on HardSurface Cleaning.Current edition approved Aug.1,2014.Published September 2014.Originallyapproved in 1953.Last previous edition approved in 2007 as D1280 00(2007).DOI:10.1520/D1280-14.2For 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 States1 5.Test Specimens5.1 The test specimens shall be identical in composition,metallurgy,and surface finishing,with the conditions of themetal at the stage where cleaning will be applied in practice.The specimens shall have an area between 0.300 and 0.375dm2,and a length not to exceed 200 mm.(A specimen 18 by85 by 1 mm in thickness would have an area of 0.327 dm2.)Atleast t
