1、Designation:D220200(Reapproved 2019)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
2、 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 valu

10、 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
11、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
