Designation:D220200(Reapproved 2014)Standard Test Method forSlump of Sealants1This standard is issued under the fixed designation D2202;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 test method covers a laboratory procedure for thedetermination of the degree of slump of a sealant when used ina vertical joint in a structure.1.2 The values stated in either inch-pound or SI(metric)units are to be separately regarded as the standard.Within thetext,the inch-pound units are shown in parentheses.1.3 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.NOTE1Arelated ISO standard is ISO 7390.The user should compareto determine how it differs from this test method.2.Referenced Documents2.1 ASTM Standards:2C717 Terminology of Building Seals and Sealants2.2 ISO Standards:3ISO 7390 Building ConstructionSealantsDetermination ofResistance to Flow3.Terminology3.1 DefinitionsRefer to Terminology C717 for definitionsof the following terms found in this test method:bead,joint,sealant.4.Significance and Use4.1 Excessive sealant slump or sag in a vertical joint maycause improper bead shape or inadequate sealant thickness inthe completed joint.Slump measurements,as described in thistest method,serve to evaluate only this application character-istic;they do not predict the performance capability of thesealant after installation.5.Apparatus5.1 Flow Test Jig,constructed in accordance with Fig.1(SIunits)or Fig.2(inch-pound units).NOTE2Most existing flow test jigs have been constructed in inch-pound units.Preferred construction of new jigs is as described in Fig.1 inSI units.5.2 Gravity Convection Oven,having a temperature con-trolled at 50 6 2C(122 6 3.6F).5.3 Steel Spatula:5.4 Plastic Scraper,such as an ordinary 114 by 114-mm(412by 412-in.)plastic tile.6.Reagent6.1 Solvent,such as methyl ethyl ketone.7.Sampling7.1 Take test specimens from a previously unopened con-tainer and mix thoroughly before using,if required for homo-geneity.8.Conditioning8.1 Condition both the test jig and the sealant to be testedfor at least 5 h at 23 6 2C(73.4 6 3.6F).9.Procedure9.1 Thoroughly clean the test jig with the solvent;then placeit on a level table with the front face upward and the plungerdepressed to the limit of its travel.9.2 Place the mixed,conditioned sealant in the jig cavity.Level the sealant flush with the surface of the block,using onegentle upward stroke of the plastic scraper held at a 45 angle.Avoid forming air pockets in the sealant,especially near thesurface of the plunger.9.3 Carefully clean the area around the cavity with theplastic scraper and a cloth;then place the jig immediately on itsend and advance the plunger gently to one half its maximumtravel,or 4.75 mm(316in.).This leaves a solid cylinder ofcaulking or sealant 38.1 mm(112in.)in diameter and 4.75 mm(316in.)thick,ready to flow down the face of the instrument.1This test method is under the jurisdiction ofASTM Committee C24 on BuildingSeals and Sealants and is the direct responsibility of Subcommittee C24.20 onGeneral Test Methods.Current edition approved Dec.1,2014.Published December 2014.Originallyapproved in 1963 as D2202 63 T.Last previous edition approved in 2010 asD2202 00(2010).DOI:10.1520/D2202-00R14.2For 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.3Available from American National Standards Institute,11 W.42nd St.,13thFloor,New York,NY 10036.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 9.4 Place the jig immediately in a vertical position on a levelshelf in the oven and condition it for 30 min at 50 6 2C(1226 3.6F),taking care to avoid any movement or vibration ofthe oven during this period.9.5 At the conclusion of the 30-min period,take a reading,to the nearest 0.2 mm(0.01 in.)of the maximum point of flowof the compound.9.6 Clean the jig and recondition it as specified in 8.1.9.7 Repeat 9.1 9.5 with another specimen of sealant.10.Report10.1 Report the slump readings obtained in each of two testsfor each specimen as well as the average value.11.Precision and Bias411.1 PrecisionThe precision statements for this testmethod were obtained from two separate inter-laboratory tests.4Supporting data are available from ASTM Headquarters.Request RR:C24-1026 and RR:C24-1039.NOTE1For the Flow Test Jig,each scale division equals 2 mm.NOTE2 Material,alumi
